S2-B3/S3-05: PortfolioRiskManager, connection loss recovery, long-only lock

Current state: Strategy builds and loads correctly, passes 240+ tests,
backtest (Strategy Analyzer) works but zero trades execute on live/SIM.

Root cause identified: NT8OrderAdapter.ExecuteInNT8() is a stub - it logs
to an internal list but never calls EnterLong/EnterShort/SetStopLoss/
SetProfitTarget. Fix is ready in TASK_01_WIRE_NT8_EXECUTION.md.

Task files added (ready for Kilocode):
- TASK_01_WIRE_NT8_EXECUTION.md (CRITICAL - INT8ExecutionBridge + wiring)
- TASK_02_EMERGENCY_KILL_SWITCH.md (CRITICAL - kill switch + verbose logging)
- TASK_03_WIRE_CIRCUIT_BREAKER.md (HIGH - wire ExecutionCircuitBreaker)

Build Status: All 240+ tests passing, zero errors
Next: Run Kilocode against TASK_01, TASK_02, TASK_03 in order

-# Mandatory Coding Patterns
+# Coding Patterns — NT8 SDK Required Patterns
 
-These patterns MUST be followed in all code you write for the NT8 SDK.
+All code in the NT8 SDK MUST follow these patterns without exception.
 
-## Thread Safety - Dictionary Access
+---
 
-ALL access to shared dictionaries MUST use locks.
+## 1. Thread Safety — Lock Everything Shared
 
-### ❌ WRONG - No Lock
-```csharp
-_activeOrders[orderId] = orderStatus;  // DANGEROUS!
-```
-
-### ✅ CORRECT - With Lock
-```csharp
-lock (_lock)
-{
-    _activeOrders[orderId] = orderStatus;
-}
-```
-
-### Rule
-Every class with shared state MUST have:
+Every class with shared state must have a lock object:
 ```csharp
 private readonly object _lock = new object();
 ```
 
-Every access to shared collections MUST be inside:
+Every access to shared `Dictionary`, `List`, `Queue`, or any field touched by multiple threads:
 ```csharp
+// ❌ NEVER
+_activeOrders[orderId] = status;
+
+// ✅ ALWAYS
 lock (_lock)
 {
-    // Dictionary/List operations here
+    _activeOrders[orderId] = status;
 }
 ```
 
-## Error Handling - Try-Catch Required
-
-ALL public methods MUST have try-catch blocks.
-
-### ❌ WRONG - No Error Handling
+### Read-then-write must be atomic
 ```csharp
-public async Task<string> SubmitOrder(OrderRequest request)
+// ❌ WRONG — race condition between check and write
+if (!_orders.ContainsKey(id))
+    _orders[id] = newOrder;
+
+// ✅ CORRECT
+lock (_lock)
 {
-    var orderId = GenerateOrderId();
-    await _nt8Adapter.SubmitToNT8(orderStatus);
-    return orderId;
+    if (!_orders.ContainsKey(id))
+        _orders[id] = newOrder;
 }
 ```
 
-### ✅ CORRECT - With Error Handling
-```csharp
-public async Task<string> SubmitOrder(OrderRequest request)
-{
-    if (request == null)
-        throw new ArgumentNullException("request");
-    
-    try
-    {
-        request.Validate();
-    }
-    catch (ArgumentException ex)
-    {
-        _logger.LogError("Order validation failed: {0}", ex.Message);
-        throw;
-    }
-    
-    try
-    {
-        var orderId = GenerateOrderId();
-        await _nt8Adapter.SubmitToNT8(orderStatus);
-        return orderId;
-    }
-    catch (Exception ex)
-    {
-        _logger.LogError("Order submission failed: {0}", ex.Message);
-        throw;
-    }
-}
-```
+---
+
+## 2. Error Handling — Try-Catch on All Public Methods
 
-### Pattern Template
 ```csharp
 public ReturnType MethodName(Type parameter)
 {
-    // 1. Validate parameters (throw ArgumentNullException/ArgumentException)
+    // 1. Validate parameters first
     if (parameter == null)
         throw new ArgumentNullException("parameter");
-    
-    // 2. Try-catch for operation-specific errors
+
+    // 2. Wrap the main logic
     try
     {
-        // Main logic
+        // Implementation
+        return result;
     }
     catch (SpecificException ex)
     {
-        _logger.LogError("Specific error: {0}", ex.Message);
-        // Handle or re-throw
+        _logger.LogError("Specific failure in MethodName: {0}", ex.Message);
         throw;
     }
     catch (Exception ex)
     {
-        _logger.LogError("Unexpected error: {0}", ex.Message);
+        _logger.LogError("Unexpected failure in MethodName: {0}", ex.Message);
         throw;
     }
 }
 ```
 
-## Logging - Structured and Consistent
+---
 
-Use structured logging with string.Format (NOT string interpolation).
+## 3. Logging — Always string.Format, Never $""
 
-### Log Levels
-
-#### LogTrace - Detailed Flow
 ```csharp
-_logger.LogTrace("Entering method {0} with parameter {1}", methodName, param);
+// ❌ NEVER — C# 6 syntax, breaks NT8 compile
+_logger.LogInformation($"Order {orderId} filled");
+
+// ✅ ALWAYS
+_logger.LogInformation("Order {0} filled", orderId);
+_logger.LogWarning("Risk check failed for {0}: {1}", symbol, reason);
+_logger.LogError("Exception in {0}: {1}", "MethodName", ex.Message);
+_logger.LogCritical("Emergency flatten triggered: {0}", reason);
 ```
 
-#### LogDebug - Normal Operations
+### Log level guide
+| Level | When to use |
+|---|---|
+| `LogTrace` | Entering/exiting methods, fine-grained flow |
+| `LogDebug` | State reads, normal data flow |
+| `LogInformation` | Important events: order submitted, filled, cancelled |
+| `LogWarning` | Recoverable issues: validation failed, limit approaching |
+| `LogError` | Failures: exceptions, unexpected states |
+| `LogCritical` | System integrity issues: emergency flatten, data corruption |
+
+---
+
+## 4. Events — Never Raise Inside Locks
+
+Raising events inside a lock causes deadlocks when event handlers acquire other locks.
+
 ```csharp
-_logger.LogDebug("Order {0} state is {1}", orderId, state);
-```
-
-#### LogInformation - Important Events
-```csharp
-_logger.LogInformation("Order {0} submitted successfully at {1}", orderId, timestamp);
-_logger.LogInformation("Order {0} filled: {1} contracts @ {2:F2}", orderId, qty, price);
-```
-
-#### LogWarning - Recoverable Issues
-```csharp
-_logger.LogWarning("Order validation failed: {0}", validationError);
-_logger.LogWarning("Maximum active orders reached: {0}", maxOrders);
-```
-
-#### LogError - Failures
-```csharp
-_logger.LogError("Failed to submit order {0} to NT8: {1}", orderId, ex.Message);
-_logger.LogError("Invalid state transition: {0} -> {1}", fromState, toState);
-```
-
-#### LogCritical - System Integrity Issues
-```csharp
-_logger.LogCritical("Emergency flatten failed for {0}: {1}", symbol, ex.Message);
-```
-
-### ❌ WRONG - String Interpolation
-```csharp
-_logger.LogInformation($"Order {orderId} submitted");  // C# 6+ feature!
-```
-
-### ✅ CORRECT - string.Format
-```csharp
-_logger.LogInformation("Order {0} submitted", orderId);
-```
-
-## XML Documentation - Required
-
-ALL public and protected members MUST have XML documentation.
-
-### ❌ WRONG - No Documentation
-```csharp
-public interface IOrderManager
+// ❌ DEADLOCK RISK
+lock (_lock)
 {
-    Task<string> SubmitOrder(OrderRequest request);
+    _state = newState;
+    OrderStateChanged?.Invoke(this, args);  // handler may try to acquire _lock
 }
-```
 
-### ✅ CORRECT - With Documentation
-```csharp
-/// <summary>
-/// Order management interface - manages complete order lifecycle
-/// </summary>
-public interface IOrderManager
+// ✅ CORRECT
+OrderState newState;
+lock (_lock)
 {
-    /// <summary>
-    /// Submit new order for execution
-    /// </summary>
-    /// <param name="request">Order request with all parameters</param>
-    /// <returns>Unique order ID for tracking</returns>
-    /// <exception cref="ArgumentNullException">Request is null</exception>
-    /// <exception cref="ArgumentException">Request validation fails</exception>
-    Task<string> SubmitOrder(OrderRequest request);
+    newState = CalculateNewState();
+    _state = newState;
 }
+// Raise AFTER releasing lock
+RaiseOrderStateChanged(orderId, previousState, newState);
 ```
 
-### Template
-```csharp
-/// <summary>
-/// Brief description of what this does (one line)
-/// </summary>
-/// <param name="paramName">What this parameter represents</param>
-/// <returns>What this method returns</returns>
-/// <exception cref="ExceptionType">When this exception is thrown</exception>
-public ReturnType MethodName(Type paramName)
-{
-    // Implementation
-}
-```
+---
 
-## Constructor Pattern
+## 5. Constructor — Validate All Dependencies
 
-### ❌ WRONG - No Validation
 ```csharp
-public BasicOrderManager(ILogger logger, INT8OrderAdapter adapter)
-{
-    _logger = logger;
-    _adapter = adapter;
-}
-```
-
-### ✅ CORRECT - Validate Dependencies
-```csharp
-public BasicOrderManager(ILogger<BasicOrderManager> logger, INT8OrderAdapter adapter)
+public MyClass(ILogger<MyClass> logger, ISomeDependency dep)
 {
     if (logger == null)
         throw new ArgumentNullException("logger");
-    if (adapter == null)
-        throw new ArgumentNullException("adapter");
-    
+    if (dep == null)
+        throw new ArgumentNullException("dep");
+
     _logger = logger;
-    _adapter = adapter;
-    
+    _dep = dep;
+
+    // Initialize collections
     _activeOrders = new Dictionary<string, OrderStatus>();
-    _completedOrders = new Dictionary<string, OrderStatus>();
-    
-    // Register callbacks
-    _adapter.RegisterOrderCallback(OnNT8OrderUpdate);
-    
-    _logger.LogInformation("BasicOrderManager initialized");
+
+    _logger.LogInformation("MyClass initialized");
 }
 ```
 
-## Event Raising Pattern
+---
 
-NEVER raise events inside locks (prevents deadlocks).
+## 6. XML Documentation — Required on All Public Members
 
-### ❌ WRONG - Event Inside Lock
 ```csharp
-lock (_lock)
+/// <summary>
+/// Brief one-line description of what this does.
+/// </summary>
+/// <param name="intent">The trading intent to validate.</param>
+/// <param name="context">Current strategy context with account state.</param>
+/// <returns>Risk decision indicating allow or reject.</returns>
+/// <exception cref="ArgumentNullException">Thrown when intent or context is null.</exception>
+public RiskDecision ValidateOrder(StrategyIntent intent, StrategyContext context)
 {
-    order.State = newState;
-    OrderStateChanged?.Invoke(this, eventArgs);  // DEADLOCK RISK!
+    ...
 }
 ```
 
-### ✅ CORRECT - Event Outside Lock
+---
+
+## 7. NT8-Specific Patterns (NinjaScript)
+
+When writing code that runs inside NinjaTrader (in `NT8.Adapters/`):
+
 ```csharp
-OrderState previousState;
-OrderState newState;
-
-lock (_lock)
+// Always guard OnBarUpdate
+protected override void OnBarUpdate()
 {
-    previousState = order.State;
-    order.State = newState;
-    // Update state inside lock
+    if (BarsInProgress != 0) return;
+    if (CurrentBar < BarsRequiredToTrade) return;
+    // ...
 }
 
-// Raise event OUTSIDE lock
-RaiseOrderStateChanged(orderId, previousState, newState, reason);
+// Managed order pattern — set stops BEFORE entry
+SetStopLoss("SignalName", CalculationMode.Ticks, stopTicks, false);
+SetProfitTarget("SignalName", CalculationMode.Ticks, targetTicks);
+EnterLong(contracts, "SignalName");
+
+// Use string.Format for Print() too
+Print(string.Format("Order submitted: {0} contracts at {1}", qty, price));
 ```

-# C# 5.0 Syntax Requirements
+# C# 5.0 Syntax — Required for NT8 SDK
 
-You are working on a .NET Framework 4.8 project that MUST use C# 5.0 syntax only.
+This project targets **.NET Framework 4.8** and must use **C# 5.0 syntax only**.  
+NinjaTrader 8's NinjaScript compiler does not support C# 6+ features.
 
-## Forbidden C# 6+ Features
+---
+
+## Forbidden Patterns (with fixes)
 
 ### String Interpolation (C# 6)
-❌ NEVER use: `$"Order {orderId} at {price}"`
-✅ ALWAYS use: `string.Format("Order {0} at {1}", orderId, price)`
-
-### Null-Conditional Operators (C# 6)
-❌ NEVER use: `var name = order?.Name`
-❌ NEVER use: `var value = dict?[key]`
-✅ ALWAYS use explicit null checks:
 ```csharp
-var name = order != null ? order.Name : null;
-if (dict != null && dict.ContainsKey(key)) { }
+// ❌ NEVER
+_logger.LogInformation($"Order {orderId} filled at {price}");
+
+// ✅ ALWAYS
+_logger.LogInformation("Order {0} filled at {1}", orderId, price);
+```
+
+### Null-Conditional Operator (C# 6)
+```csharp
+// ❌ NEVER
+var name = order?.Symbol;
+
+// ✅ ALWAYS
+var name = order != null ? order.Symbol : null;
 ```
 
 ### Null-Coalescing Assignment (C# 8)
-❌ NEVER use: `value ??= defaultValue;`
-✅ ALWAYS use: `if (value == null) value = defaultValue;`
+```csharp
+// ❌ NEVER
+value ??= defaultValue;
+
+// ✅ ALWAYS
+if (value == null) value = defaultValue;
+```
 
 ### Expression-Bodied Members (C# 6)
-❌ NEVER use: `public int Property => value;`
-❌ NEVER use: `public void Method() => DoSomething();`
-✅ ALWAYS use full syntax:
 ```csharp
-public int Property 
-{ 
-    get { return value; } 
-}
+// ❌ NEVER
+public int Contracts => _contracts;
+public void Reset() => _contracts = 0;
 
-public void Method()
-{
-    DoSomething();
-}
+// ✅ ALWAYS
+public int Contracts { get { return _contracts; } }
+public void Reset() { _contracts = 0; }
 ```
 
 ### nameof Operator (C# 6)
-❌ NEVER use: `throw new ArgumentNullException(nameof(param));`
-✅ ALWAYS use: `throw new ArgumentNullException("param");`
+```csharp
+// ❌ NEVER
+throw new ArgumentNullException(nameof(intent));
+
+// ✅ ALWAYS
+throw new ArgumentNullException("intent");
+```
 
 ### Auto-Property Initializers (C# 6)
-❌ NEVER use: `public int Property { get; set; } = 10;`
-✅ ALWAYS use constructor initialization:
 ```csharp
-public int Property { get; set; }
+// ❌ NEVER
+public bool IsEnabled { get; set; } = true;
 
-public ClassName()
-{
-    Property = 10;
-}
+// ✅ ALWAYS — initialize in constructor
+public bool IsEnabled { get; set; }
+public MyClass() { IsEnabled = true; }
 ```
 
-### Using Static (C# 6)
-❌ NEVER use: `using static System.Math;`
-✅ ALWAYS use: `System.Math.Floor(...)`
+### Inline Out Variable Declaration (C# 7)
+```csharp
+// ❌ NEVER
+if (_orders.TryGetValue(id, out var status)) { ... }
 
-### Tuple Syntax (C# 7)
-❌ NEVER use: `var tuple = (name: "test", value: 1);`
-✅ ALWAYS use: `Tuple<string, int>` or custom classes
+// ✅ ALWAYS
+OrderStatus status;
+if (_orders.TryGetValue(id, out status)) { ... }
+```
 
-### Pattern Matching (C# 7+)
-❌ NEVER use: `if (obj is string str)`
-✅ ALWAYS use: `if (obj is string) { var str = (string)obj; }`
+### Pattern Matching (C# 7)
+```csharp
+// ❌ NEVER
+if (obj is string s) { ... }
+
+// ✅ ALWAYS
+if (obj is string) { var s = (string)obj; ... }
+```
 
 ### Local Functions (C# 7)
-❌ NEVER use functions inside methods
-✅ ALWAYS use private methods
-
-### Out Variables (C# 7)
-❌ NEVER use: `if (dict.TryGetValue(key, out var value))`
-✅ ALWAYS use:
 ```csharp
-OrderStatus value;
-if (dict.TryGetValue(key, out value))
-{
-    // Use value
+// ❌ NEVER — function inside a method
+public void Execute() {
+    void Helper() { ... }
+    Helper();
 }
+
+// ✅ ALWAYS — use private methods
+private void Helper() { ... }
+public void Execute() { Helper(); }
 ```
 
-## Verification
-After writing ANY code, verify C# 5.0 compliance:
-- No `$` signs except in string literals
-- No `?.` or `?[` operators
-- No `=>` except in lambda expressions
-- No inline variable declarations in out parameters
+### Tuple Literals (C# 7)
+```csharp
+// ❌ NEVER
+var result = (price: 100.0, qty: 5);
+
+// ✅ ALWAYS — use Tuple<T1,T2> or a named class
+var result = Tuple.Create(100.0, 5);
+```
+
+### using static (C# 6)
+```csharp
+// ❌ NEVER
+using static System.Math;
+
+// ✅ ALWAYS
+System.Math.Floor(x);
+Math.Floor(x); // (via standard using System;)
+```

+
+## Quick Self-Check Before Saving
+
+- Search your code for `$"` — if found, replace every occurrence
+- Search for `?.` — if found, replace with null check
+- Search for `=>` — if on a property or method, rewrite as full block
+- Search for `nameof` — replace with string literal
+- Search for `out var` — split into declaration + assignment

-## New File Creation Rules
-
-### When creating new files:
-1. Use proper namespace: 
-   - `NT8.Core.Risk` for risk files
-   - `NT8.Core.Sizing` for sizing files
-   - `NT8.Core.OMS` for OMS files
-   - `NT8.Core.Tests.Risk` for risk tests
-   - `NT8.Core.Tests.Sizing` for sizing tests
-
-2. Include XML documentation on all public members
-3. Follow existing file naming patterns (PascalCase)
-4. Add to appropriate project file if needed
-
-### File naming examples:
-✅ `AdvancedRiskManager.cs` - Implementation class
-✅ `AdvancedRiskModels.cs` - Model classes
-✅ `OptimalFCalculator.cs` - Calculator utility
-✅ `EnhancedPositionSizer.cs` - Sizer implementation
-✅ `AdvancedRiskManagerTests.cs` - Test class
-
-## Modification Patterns
-
-### ✅ CORRECT: Adding to existing file
-```csharp
-// In RiskConfig.cs - ADD new properties
-public record RiskConfig(
-    // Phase 1 properties - DON'T TOUCH
-    double DailyLossLimit,
-    double MaxTradeRisk,
-    int MaxOpenPositions,
-    bool EmergencyFlattenEnabled,
-    
-    // Phase 2 properties - ADD THESE
-    double? WeeklyLossLimit = null,
-    double? TrailingDrawdownLimit = null,
-    int? MaxCrossStrategyExposure = null
-);
-```
-
-### ❌ WRONG: Modifying existing
-```csharp
-// DON'T change existing property types or remove them
-public record RiskConfig(
-    int DailyLossLimit,  // ❌ Changed type from double
-    // ❌ Removed MaxTradeRisk property
-);
-```
-
-### ✅ CORRECT: Adding methods to BasicOrderManager
-```csharp
-public class BasicOrderManager : IOrderManager
-{
-    // Existing methods - DON'T TOUCH
-    public async Task<string> SubmitOrderAsync(...) { }
-    
-    // NEW Phase 2 methods - ADD THESE
-    public async Task<bool> HandlePartialFillAsync(...) { }
-    public async Task<bool> RetryOrderAsync(...) { }
-}
-```
-
-## Verification
-
-Before any file operation, ask yourself:
-1. Is this file in an allowed directory?
-2. Am I modifying an existing interface signature? (FORBIDDEN)
-3. Am I changing existing Phase 1 behavior? (FORBIDDEN)
-4. Am I only ADDING to existing files? (ALLOWED)
-
-If unsure, DO NOT proceed - ask for clarification first.
-
-## Phase 2 Specific Rules
-
-### Risk Files

-# Project Context - Phase 2
+# Project Context — NT8 SDK (Production Hardening Phase)
 
-You are working on the **NT8 SDK** - an institutional-grade trading SDK for NinjaTrader 8.
+You are working on the **NT8 SDK** — an institutional-grade algorithmic trading framework for NinjaTrader 8.
+This is production trading software. Bugs cause real financial losses.
 
-## Project Purpose
+---
 
-This is production trading software used for automated futures trading (ES, NQ, MES, MNQ, CL, GC). Code quality is critical because:
-- Bugs can cause real financial losses
-- System runs 24/5 during market hours
-- Performance requirements are strict (<200ms latency)
-- This is institutional-grade, not hobbyist code
+## What Is Already Built (Do Not Touch)
 
-## Current Phase: Phase 2 - Enhanced Risk & Sizing
+All core trading logic is complete and has 240+ passing tests:
 
-You are implementing **advanced risk management and intelligent position sizing**.
+| Layer | Status | Key Files |
+|---|---|---|
+| Risk (Tier 1-3) | ✅ Complete | `src/NT8.Core/Risk/` |
+| Position Sizing | ✅ Complete | `src/NT8.Core/Sizing/` |
+| OMS / Order Lifecycle | ✅ Complete | `src/NT8.Core/OMS/` |
+| Intelligence | ✅ Complete | `src/NT8.Core/Intelligence/` |
+| Analytics | ✅ Complete | `src/NT8.Core/Analytics/` |
+| Execution Utilities | ✅ Complete | `src/NT8.Core/Execution/` |
+| Market Data | ✅ Complete | `src/NT8.Core/MarketData/` |
 
-### Phase 2 Responsibilities
-- Advanced risk rules (Tiers 2-3)
-- Optimal-f position sizing (Ralph Vince method)
-- Volatility-adjusted sizing
-- Enhanced OMS features (partial fills, retry, reconciliation)
+**NT8 Order Execution is ALREADY WIRED.**
+`NT8StrategyBase.SubmitOrderToNT8()` calls `EnterLong`, `EnterShort`, `SetStopLoss`, and
+`SetProfitTarget` directly. The execution path works end-to-end. Do not re-implement it.
 
-### What Phase 2 Does NOT Do (Other Components Handle)
-- Basic risk validation (BasicRiskManager handles this - Phase 1)
-- Strategy logic (IStrategy handles this - Phase 1)
-- Order lifecycle management (BasicOrderManager handles this - Phase 1)
-- Direct NT8 calls (NT8Adapter handles this - Future)
+---
 
-## Architecture Overview
+## What You Are Fixing (The Active Task List)
+
+### CRITICAL — `NT8StrategyBase.cs`
+
+**Gap 1 — No kill switch**
+`NT8StrategyBase` has no `EnableKillSwitch` NinjaScript parameter and no early-exit in `OnBarUpdate()`.
+A runaway strategy cannot be stopped without killing NinjaTrader.
+**Fix:** Add `EnableKillSwitch` (bool NinjaScript property) and `EnableVerboseLogging` property.
+Add kill switch check as the FIRST thing in `OnBarUpdate()`.
+→ See `TASK-01-kill-switch.md`
+
+**Gap 2 — `ExecutionCircuitBreaker` not wired**
+`src/NT8.Core/Execution/ExecutionCircuitBreaker.cs` is complete and tested.
+It is never instantiated. Orders submit regardless of latency or rejection conditions.
+**Fix:** Instantiate in `InitializeSdkComponents()`, gate orders in `SubmitOrderToNT8()`, wire rejections in `OnOrderUpdate()`.
+→ See `TASK-02-circuit-breaker.md`
+
+### HIGH — `TrailingStopManager.cs`
+
+**Gap 3 — Placeholder stop math returns zero**
+`CalculateNewStopPrice()` FixedTrailing branch: `marketPrice - (x - x)` = always zero movement.
+ATRTrailing and Chandelier also have meaningless placeholder formulas.
+**Fix:** Replace with real calculations using `TrailingStopConfig.TrailingAmountTicks` and `AtrMultiplier`.
+→ See `TASK-03-trailing-stop.md`
+
+### HIGH — `BasicLogger.cs`
+
+**Gap 4 — No log-level filter**
+Every log statement writes to console unconditionally. Cannot suppress debug noise in production.
+**Fix:** Add `MinimumLevel` property (defaults to `Information`). Suppress messages below threshold.
+→ See `TASK-04-log-level.md`
+
+### MEDIUM — `SessionManager.cs`
+
+**Gap 5 — No holiday awareness**
+`IsRegularTradingHours()` checks session times only. Will attempt to trade on Christmas, Thanksgiving, etc.
+**Fix:** Add static CME holiday set for 2025/2026. Return `false` on those dates.
+→ See `TASK-05-session-holidays.md`

-## Your Current Task
-
-Implement **Enhanced Risk & Sizing** with these deliverables:
-
-### Phase 2 Deliverables
-**Risk Management:**
-1. ✅ `AdvancedRiskModels.cs` - Weekly tracking, drawdown, exposure
-2. ✅ `AdvancedRiskManager.cs` - All Tier 2-3 risk rules
-3. ✅ Update `RiskConfig.cs` - Add new configuration properties
-
-**Position Sizing:**
-4. ✅ `SizingModels.cs` - Optimal-f, volatility models
-5. ✅ `OptimalFCalculator.cs` - Ralph Vince algorithm
-6. ✅ `VolatilityAdjustedSizer.cs` - ATR/StdDev sizing
-7. ✅ `EnhancedPositionSizer.cs` - All advanced sizing methods
-
-**Enhanced OMS:**
-8. ✅ `OrderStateMachine.cs` - Formal state machine
-9. ✅ Update `OrderModels.cs` - Add partial fill models
-10. ✅ Update `BasicOrderManager.cs` - Add enhanced methods
-
-**Testing:**
-11. ✅ Comprehensive unit tests (90+ tests total)
-12. ✅ Integration tests (risk + sizing flow)
-13. ✅ Performance benchmarks (<5ms risk, <3ms sizing)
-
-### Out of Scope (Future Phases)
-- ❌ Market microstructure (Phase 3)
-- ❌ Advanced order types (Phase 3)
-- ❌ Confluence scoring (Phase 4)
-- ❌ ML-based features (Phase 6)
-
-## Key Design Principles
-
-### 1. Risk-First Architecture
-ALL trading operations flow through risk management before execution.
-The pattern is: Strategy → Risk → Sizing → OMS → NT8
-**NEVER bypass risk checks.**
-
-### 2. Backward Compatibility
-Phase 2 MUST NOT break Phase 1:
-- BasicRiskManager still works
-- BasicPositionSizer still works
-- BasicOrderManager still works
-- No interface signature changes
-
-### 3. Thread Safety
-This system will run with:
-- Multiple strategies executing simultaneously
-- Multiple NT8 callbacks firing
-- UI queries happening during trading
-- State changes from external events
-
-ALL shared state MUST be protected with locks.
-
-### 4. Performance Targets
-- Risk validation: <5ms (was <10ms in Phase 1)
-- Sizing calculation: <3ms (was <5ms in Phase 1)
-- Overall tick-to-trade: <200ms (unchanged)
-- No degradation to Phase 1 performance
-
-### 5. Determinism
-All calculations must be deterministic for:
-- Backtesting accuracy
-- Replay debugging
-- Audit trails
+---
 
 ## Technology Constraints
 
-### Language & Framework
-- C# 5.0 syntax ONLY (no C# 6+)
-- .NET Framework 4.8 (not .NET Core/5+/6+)
-- Target: Windows desktop environment
-
-### Libraries
-- ✅ Newtonsoft.Json (for serialization)
-- ✅ Microsoft.Extensions.Logging (for logging)
-- ✅ Microsoft.Extensions.DependencyInjection (for DI)
-- ❌ System.Text.Json (not available)
-- ❌ Any .NET Core/5+/6+ libraries
-
-### Testing
-- xUnit for test framework
-- FluentAssertions for assertions
-- Bogus for test data generation (if needed)
-- Mock adapters for isolation
-
-## Reference Documents

-
-## Communication
-
-When you need clarification:
-1. Check `Phase2_Implementation_Guide.md` first
-2. Check existing Phase 1 code patterns
-3. If still uncertain, ask before implementing
-
-**Remember:** This is production trading code. When in doubt, ask rather than guess.

 # Verification Requirements
 
-You MUST verify your work at each checkpoint to ensure code quality and prevent errors.
+Run `.\verify-build.bat` from `C:\dev\nt8-sdk\` after **every single file change**.  
+Do not proceed to the next task until this passes.
 
-## After EVERY File Creation or Modification
+---
 
-### Step 1: Run Build Verification
-```bash
+## After Every File Change
+
+### Step 1 — Build verification
+```bat
+cd C:\dev\nt8-sdk
 .\verify-build.bat
 ```
 
-**Expected Output:**
-```
-✅ All checks passed!
-```
+Expected: `✅ All checks passed!`
 
-**If build fails:**
-1. Read the error message carefully
-2. Fix the error immediately
-3. Re-run verify-build.bat
-4. DO NOT proceed to next file until build passes
+If it fails:
+1. Read the compiler error carefully
+2. Fix it immediately
+3. Re-run before continuing
+4. NEVER move to the next file with a broken build
 
-### Step 2: Verify File Location
-Check that the file is in an allowed directory:
-- ✅ `src/NT8.Core/OMS/` - Implementation files
-- ✅ `tests/NT8.Core.Tests/OMS/` - Test files
-- ✅ `tests/NT8.Core.Tests/Mocks/` - Mock files
-- ❌ Anywhere else - STOP and ask
-
-### Step 3: Check Syntax Compliance
+### Step 2 — Syntax check (self-audit before running)
 Scan your code for forbidden patterns:
-- ❌ No `$"..."` - Use `string.Format()`
-- ❌ No `?.` or `?[` - Use explicit null checks
-- ❌ No `=>` in properties/methods - Use full syntax
-- ❌ No `nameof()` - Use string literals
+- No `$"..."` (string interpolation) → use `string.Format("...", a, b)`
+- No `?.` or `?[` → use explicit null checks
+- No `=>` on properties or methods → use full `{ get { return x; } }` syntax
+- No `nameof(x)` → use `"x"` string literal
+- No `var x; ...TryGetValue(key, out var x)` inline → declare var separately
 
-## After Completing Each Class
+### Step 3 — After completing a whole class
+```bat
+dotnet test tests\NT8.Core.Tests --verbosity minimal
+```
+All existing tests must still pass. Zero regressions allowed.
 
-### Step 4: Run Unit Tests (if applicable)
-```bash
-dotnet test tests\NT8.Core.Tests --filter "FullyQualifiedName~OMS"
+---
+
+## Specific Test Commands by Area
+
+```bat
+# Test execution layer (TrailingStopManager etc.)
+dotnet test tests\NT8.Core.Tests --filter "FullyQualifiedName~Execution"
+
+# Test adapters
+dotnet test tests\NT8.Core.Tests --filter "FullyQualifiedName~Adapters"
+
+# Test all integration tests
+dotnet test tests\NT8.Integration.Tests --verbosity minimal
+
+# Full suite
+dotnet test NT8-SDK.sln --verbosity minimal
 ```
 
-**Expected Output:**
-```
-Passed! - Failed: 0, Passed: X
-```
-
-### Step 5: Review Against Checklist
-- [ ] All public members have XML documentation
-- [ ] All dictionary access uses `lock (_lock)`
-- [ ] All public methods have try-catch
-- [ ] All logging uses `string.Format()`
-- [ ] No C# 6+ syntax anywhere
-- [ ] File compiles without warnings
-
-## After Completing Full Task
-
-### Step 6: Comprehensive Build
-```bash
-dotnet build NT8-SDK.sln --configuration Release
-```
-
-### Step 7: Full Test Suite
-```bash
-dotnet test tests\NT8.Core.Tests --verbosity normal
-```
-
-### Step 8: Code Coverage (Optional but Recommended)
-```bash
-dotnet test tests\NT8.Core.Tests --collect:"XPlat Code Coverage"
-```
-
-**Target:** >80% coverage for new code
-
-## Common Verification Failures
-
-### "Feature 'string interpolation' is not available"
-**Cause:** Used `$"text {var}"`
-**Fix:** Replace with `string.Format("text {0}", var)`
-
-### "Feature 'null-conditional operator' is not available"
-**Cause:** Used `obj?.Property`
-**Fix:** Replace with explicit null check
-
-### "Cannot access member before initialization"
-**Cause:** Used auto-property initializer
-**Fix:** Move initialization to constructor
-
-### Lock-related warnings
-**Cause:** Dictionary access outside lock
-**Fix:** Wrap in `lock (_lock) { ... }`
+---
 
 ## Emergency Stop Conditions
 
-STOP immediately and ask for help if:
-1. ❌ Build fails with errors you don't understand
-2. ❌ Tests fail unexpectedly after your changes
-3. ❌ You need to modify files outside allowed directories
-4. ❌ You're unsure about a design decision
-5. ❌ Performance is severely degraded
+STOP and report back if:
+- Build fails with errors you do not understand
+- Existing tests fail after your changes
+- You need to touch a file outside allowed boundaries
+- You are unsure about a design decision
+- You are about to modify a NinjaTrader API call signature

+## Quality Gates (ALL must pass before task is complete)
 
-## Quality Gates
-
-Your code MUST pass these gates before being considered complete:
-
-### Gate 1: Compilation
-- ✅ `verify-build.bat` outputs "All checks passed!"
-- ✅ No compiler warnings
-- ✅ All references resolve
-
-### Gate 2: Syntax Compliance
-- ✅ No C# 6+ features detected
-- ✅ Only .NET Framework 4.8 APIs used
-- ✅ Proper using statements
-
-### Gate 3: Pattern Compliance
-- ✅ Thread-safe operations
-- ✅ Error handling present
-- ✅ Logging at correct levels
-- ✅ XML documentation complete
-
-### Gate 4: Testing

-- ✅ Coverage >80% (target)
-- ✅ Edge cases tested
-
-## Self-Check Questions
-
-Before marking a file complete, ask:
-1. Does `verify-build.bat` pass?
-2. Did I use any C# 6+ syntax?
-3. Is all dictionary access inside locks?
-4. Do all public methods have try-catch?
-5. Does all logging use string.Format?
-6. Do all public members have XML docs?
-7. Are there unit tests for this code?
-8. Do the tests pass?
-
-**If any answer is "No" or "I'm not sure" → DO NOT PROCEED**
+| Gate | Check |
+|---|---|
+| ✅ Compilation | `verify-build.bat` outputs "All checks passed!" |
+| ✅ Syntax | No C# 6+ features |
+| ✅ Thread safety | All shared `Dictionary`/`List` access inside `lock (_lock)` |
+| ✅ Error handling | All public methods have `try-catch` |
+| ✅ Logging | All log calls use `string.Format()` not `$""` |
+| ✅ XML docs | All public members have `/// <summary>` |

+
+---
+
+## 🔧 Fix 1: NT8StrategyBase.cs - Ambiguous `Position` reference (Errors 2 & 3)
+
+### Problem
+NT8's `NinjaTrader.Cbi.Position` and our `NT8.Core.Common.Models.Position` both exist
+in scope. C# cannot resolve which one to use on lines 49 and 300.
+
+### Solution
+Add a using alias at the top of the file to disambiguate, then use the alias
+wherever SDK Position is intended.
+
+### Change 1a: Add alias to using block (top of file, after existing using aliases)
+
+**Find this block** (lines 19-25):
+```csharp
+using SdkOrderSide = NT8.Core.Common.Models.OrderSide;
+using SdkOrderType = NT8.Core.Common.Models.OrderType;
+using OmsOrderRequest = NT8.Core.OMS.OrderRequest;
+using OmsOrderSide = NT8.Core.OMS.OrderSide;
+using OmsOrderType = NT8.Core.OMS.OrderType;
+using OmsOrderState = NT8.Core.OMS.OrderState;
+using OmsOrderStatus = NT8.Core.OMS.OrderStatus;
+```
+
+**Replace with** (add one line at top):
+```csharp
+using SdkPosition = NT8.Core.Common.Models.Position;
+using SdkOrderSide = NT8.Core.Common.Models.OrderSide;
+using SdkOrderType = NT8.Core.Common.Models.OrderType;
+using OmsOrderRequest = NT8.Core.OMS.OrderRequest;
+using OmsOrderSide = NT8.Core.OMS.OrderSide;
+using OmsOrderType = NT8.Core.OMS.OrderType;
+using OmsOrderState = NT8.Core.OMS.OrderState;
+using OmsOrderStatus = NT8.Core.OMS.OrderStatus;
+```
+
+### Change 1b: Fix field declaration (line 49)
+
+**Find:**
+```csharp
+        private Position _lastPosition;
+```
+
+**Replace with:**
+```csharp
+        private SdkPosition _lastPosition;
+```
+
+### Change 1c: Fix return type in BuildPositionInfo() (line 300 area)
+
+**Find:**
+```csharp
+        private Position BuildPositionInfo()
+        {
+            var p = NT8DataConverter.ConvertPosition(
+                Instrument.MasterInstrument.Name,
+                Position.Quantity,
+                Position.AveragePrice,
+                0.0,
+                0.0,
+                DateTime.UtcNow);
+
+            _lastPosition = p;
+            return p;
+        }
+```
+
+**Replace with:**
+```csharp
+        private SdkPosition BuildPositionInfo()
+        {
+            var p = NT8DataConverter.ConvertPosition(
+                Instrument.MasterInstrument.Name,
+                Position.Quantity,
+                Position.AveragePrice,
+                0.0,
+                0.0,
+                DateTime.UtcNow);
+
+            _lastPosition = p;
+            return p;
+        }
+```
+
+**NOTE:** `Position.Quantity` and `Position.AveragePrice` (without qualifier) correctly
+refer to `NinjaTrader.Cbi.Position` (NT8's built-in position property on the Strategy
+class). Only the return type and field type need the alias. Do NOT change the
+`Position.Quantity` / `Position.AveragePrice` references.
+
+---
+
+## 🔧 Fix 2: NT8StrategyBase.cs - Volume double to long (Error 5)
+
+### Problem
+`NT8DataConverter.ConvertBar()` expects `volume` as `long`, but NT8's `Volume[0]`
+returns `double`.
+
+### Location
+Inside `ConvertCurrentBar()` method (line 273 area).
+
+### Change: Cast Volume[0] to long
+
+**Find:**
+```csharp
+        private BarData ConvertCurrentBar()
+        {
+            return NT8DataConverter.ConvertBar(
+                Instrument.MasterInstrument.Name,
+                Time[0],
+                Open[0],
+                High[0],
+                Low[0],
+                Close[0],
+                Volume[0],
+                (int)BarsPeriod.Value);
+        }
+```
+
+**Replace with:**
+```csharp
+        private BarData ConvertCurrentBar()
+        {
+            return NT8DataConverter.ConvertBar(
+                Instrument.MasterInstrument.Name,
+                Time[0],
+                Open[0],

+
+## 🔧 Fix 3: NT8StrategyBase.cs - StopTicks/TargetTicks double to int (Errors 6-9)
+
+### Problem
+`SetStopLoss()` and `SetProfitTarget()` NT8 methods expect `int` for tick counts,
+but `intent.StopTicks` and `intent.TargetTicks` are `double`.
+
+### Location
+Inside `SubmitOrderToNT8()` method (lines 364-375 area).
+
+### Change: Cast tick values to int
+
+**Find:**
+```csharp
+            if (intent.StopTicks > 0)
+                SetStopLoss(orderName, CalculationMode.Ticks, intent.StopTicks, false);
+
+            if (intent.TargetTicks.HasValue && intent.TargetTicks.Value > 0)
+                SetProfitTarget(orderName, CalculationMode.Ticks, intent.TargetTicks.Value);
+```
+
+**Replace with:**
+```csharp
+            if (intent.StopTicks > 0)
+                SetStopLoss(orderName, CalculationMode.Ticks, (int)intent.StopTicks, false);
+
+            if (intent.TargetTicks.HasValue && intent.TargetTicks.Value > 0)
+                SetProfitTarget(orderName, CalculationMode.Ticks, (int)intent.TargetTicks.Value);
+```
+

+
+## 🔧 Fix 4: SimpleORBNT8.cs - Missing NT8.Strategies reference (Errors 1 & 4)
+
+### Problem
+`SimpleORBStrategy` lives in the `NT8.Strategies.Examples` namespace. The using
+directive references `NT8.Strategies.Examples` but NT8.Strategies.dll must also be
+deployed to NT8 Custom folder AND added as a reference in the NinjaScript Editor.
+
+### Change: Add using alias at top of SimpleORBNT8.cs
+
+**Find** (line 15):
+```csharp
+using NT8.Strategies.Examples;
+```
+
+**Replace with:**
+```csharp
+using NT8.Strategies.Examples;
+using SdkSimpleORB = NT8.Strategies.Examples.SimpleORBStrategy;
+```
+
+**AND** update the usage inside `CreateSdkStrategy()`:
+
+**Find:**
+```csharp
+        protected override IStrategy CreateSdkStrategy()
+        {
+            return new SimpleORBStrategy(OpeningRangeMinutes, StdDevMultiplier);
+        }
+```
+
+**Replace with:**
+```csharp
+        protected override IStrategy CreateSdkStrategy()
+        {
+            return new SdkSimpleORB(OpeningRangeMinutes, StdDevMultiplier);
+        }
+```
+
+---
+
+## 📦 Deployment Step (Manual - Not Kilocode)
+
+**After code fixes are committed**, Mo needs to:
+
+```powershell
+# Build NT8.Strategies project
+cd C:\dev\nt8-sdk
+dotnet build src\NT8.Strategies\NT8.Strategies.csproj --configuration Release
+
+# Copy DLL to NT8 Custom folder (NT8 must be closed)
+Copy-Item "src\NT8.Strategies\bin\Release\net48\NT8.Strategies.dll" `
+    "$env:USERPROFILE\Documents\NinjaTrader 8\bin\Custom\" -Force
+```
+
+Then in NT8 NinjaScript Editor:
+- Right-click → References → Add → NT8.Strategies.dll
+
+---
+
+## ✅ Verification Steps
+
+### After Code Changes:
+```bash
+# Build must succeed with zero errors
+dotnet build src\NT8.Adapters\NT8.Adapters.csproj --configuration Release
+
+# All tests must still pass
+dotnet test NT8-SDK.sln --configuration Release --no-build
+```
+
+### After NT8 Recompile:
+- [ ] Zero compilation errors in NinjaScript Editor
+- [ ] MinimalTestStrategy visible in strategy list
+- [ ] SimpleORBNT8 visible in strategy list
+- [ ] NT8StrategyBase not directly visible (abstract)
+
+---
+
+## 🚨 Constraints
+
+- C# 5.0 syntax only - no modern features
+- Surgical edits ONLY - do not refactor or redesign
+- Do NOT change any logic, only fix the type issues
+- Preserve all XML documentation comments
+- All 319 existing tests must still pass after changes
+
+---
+
+## 📋 Git Commit
+
+```bash
+git add src/NT8.Adapters/Strategies/NT8StrategyBase.cs
+git add src/NT8.Adapters/Strategies/SimpleORBNT8.cs
+git commit -m "fix: Resolve NT8 NinjaScript compilation errors
+
+- Add SdkPosition alias to disambiguate from NinjaTrader.Cbi.Position
+- Cast Volume[0] from double to long for ConvertBar()
+- Cast StopTicks/TargetTicks from double to int for SetStopLoss/SetProfitTarget
+- Add SdkSimpleORB alias for SimpleORBStrategy in SimpleORBNT8.cs
+
+All 9 NT8 compile errors resolved. Zero logic changes."
+```
+
+---
+
+## 🎯 Success Criteria
+
+- [ ] Zero compilation errors in NT8 NinjaScript Editor
+- [ ] All 319 existing tests still passing
+- [ ] Zero new build warnings
+- [ ] Code committed to Git

+# Configuration Export/Import - Implementation Specification
+
+**For:** Kilocode AI Agent  
+**Priority:** HIGH  
+**Mode:** Code Mode  
+**Estimated Time:** 1.5-2 hours  
+**Files to Edit:** 1 file (NT8StrategyBase.cs)  
+**Files to Create:** 1 file (StrategyConfigExporter.cs)  
+
+---
+
+## 🎯 Objective
+
+Add ability to export NT8 strategy configuration as JSON for:
+- Easy sharing with support/debugging
+- Version control of strategy settings
+- Configuration backup/restore
+- Reproducible backtests
+
+---
+
+## 📋 What We're Adding
+
+### 1. Export Configuration Button/Method
+User can click a button (or call a method) to export all strategy settings as JSON file.
+
+### 2. Import Configuration Method
+User can load settings from a previously exported JSON file.
+
+### 3. Automatic Export on Strategy Start
+Optionally auto-export config to a timestamped file when strategy starts.

+
+## ✅ Verification
+
+### Manual Test
+
+1. **Build:**
+```bash
+dotnet build src\NT8.Adapters\NT8.Adapters.csproj --configuration Release
+```
+
+2. **Deploy:**
+```powershell
+.\deployment\Deploy-To-NT8.ps1
+```
+
+3. **Test in NT8:**
+   - Add SimpleORBNT8 to Strategy Analyzer
+   - Enable strategy
+   - Check Output window - should see:
+   ```
+   [SDK] Simple ORB NT8 initialized successfully
+   === Strategy Configuration ===
+   {
+     "StrategyName": "Simple ORB NT8",
+     "ExportedAt": "2026-02-17 14:30:00",
+     "Instrument": "ES 03-26",
+     "BarsPeriod": "5 Minute",
+     "EnableSDK": true,
+     "DailyLossLimit": 1000,
+     ...
+   }
+   === End Configuration ===
+   ```
+
+4. **Copy JSON from Output window** - ready to share!
+
+5. **Test Auto-Export:**
+   - Set `AutoExportConfig = true`
+   - Re-enable strategy
+   - Check `Documents\NinjaTrader 8\logs\` folder
+   - Should see `SimpleORBNT8_[timestamp]_config.json`

+# Designed vs. Implemented Features - Gap Analysis
+
+**Date:** February 17, 2026  
+**Status:** Post Phase A-B-C NT8 Integration  
+**Purpose:** Identify what was designed but never implemented  
+
+---
+
+## 🎯 Critical Finding
+
+You're absolutely right - several **designed features were never implemented**. This happened during the rush to get the NT8 integration working.
+
+---
+
+## ❌ **MISSING: Debug Logging Configuration**
+
+### What Was Designed
+- **`EnableDebugLogging` property** on NT8StrategyBase
+- **`LogLevel` configuration** (Trace/Debug/Info/Warning/Error)
+- **Runtime toggle** to turn verbose logging on/off
+- **Conditional logging** based on log level
+
+### What Was Actually Implemented
+- ❌ No debug toggle property
+- ❌ No log level configuration
+- ❌ No conditional logging
+- ✅ Only basic `Print()` statements hardcoded
+
+### Impact
+- **CRITICAL** - Cannot debug strategies without recompiling
+- Cannot see what's happening inside strategy logic
+- No way to reduce log spam in production
+
+### Status
+🔴 **NOT IMPLEMENTED**
+
+---
+
+## ❌ **MISSING: Configuration Export/Import**
+
+### What Was Designed
+- **Export settings as JSON** for review/backup
+- **Import settings from JSON** for consistency
+- **Configuration templates** for different scenarios
+- **Validation on import** to catch errors
+
+### What Was Actually Implemented
+- ❌ No export functionality
+- ❌ No import functionality
+- ❌ No JSON configuration support
+- ✅ Only NT8 UI parameters (not exportable)
+
+### Impact
+- **HIGH** - Cannot share configurations between strategies
+- Cannot version control settings
+- Cannot review settings without running strategy
+- Difficult to troubleshoot user configurations
+
+### Status
+🔴 **NOT IMPLEMENTED**
+
+---
+
+## ❌ **MISSING: Enhanced Logging Framework**
+
+### What Was Designed
+- **BasicLogger with log levels** (Trace/Debug/Info/Warn/Error/Critical)
+- **Structured logging** with correlation IDs
+- **Log file rotation** (daily files, keep 30 days)
+- **Configurable log verbosity** per component
+- **Performance logging** (latency tracking)
+
+### What Was Actually Implemented
+- ⚠️  PARTIAL - BasicLogger exists but minimal
+- ❌ No log levels (everything logs at same level)
+- ❌ No file rotation
+- ❌ No structured logging
+- ❌ No correlation IDs
+
+### Impact
+- **MEDIUM** - Logs are messy and hard to filter
+- Cannot trace request flows through system
+- Log files grow unbounded
+- Difficult to diagnose production issues
+
+### Status
+🟡 **PARTIALLY IMPLEMENTED** (needs enhancement)
+
+---
+
+## ❌ **MISSING: Health Check System**
+
+### What Was Designed
+- **Health check endpoint** to query system status
+- **Component status monitoring** (strategy, risk, OMS all healthy?)
+- **Performance metrics** (average latency, error rates)
+- **Alert on degradation** (performance drops, high error rates)
+
+### What Was Actually Implemented
+- ❌ No health check system
+- ❌ No component monitoring
+- ❌ No performance tracking
+- ❌ No alerting
+
+### Impact
+- **HIGH** - Cannot monitor production system health
+- No visibility into performance degradation
+- Cannot detect issues until trades fail
+
+### Status
+🔴 **NOT IMPLEMENTED**
+
+---
+
+## ❌ **MISSING: Configuration Validation**
+
+### What Was Designed
+- **Schema validation** for configuration
+- **Range validation** (e.g., DailyLossLimit > 0)
+- **Dependency validation** (e.g., MaxTradeRisk < DailyLossLimit)
+- **Helpful error messages** on invalid config
+
+### What Was Actually Implemented
+- ⚠️  PARTIAL - NT8 has `[Range]` attributes on some properties
+- ❌ No cross-parameter validation
+- ❌ No dependency checks
+- ❌ No startup validation
+
+### Impact
+- **MEDIUM** - Users can configure invalid settings
+- Runtime errors instead of startup errors
+- Difficult to diagnose misconfiguration
+
+### Status
+🟡 **PARTIALLY IMPLEMENTED**
+
+---
+
+## ❌ **MISSING: Session Management**
+
+### What Was Designed
+- **CME calendar integration** for accurate session times
+- **Session state tracking** (pre-market, RTH, ETH, closed)
+- **Session-aware risk limits** (different limits for RTH vs ETH)
+- **Holiday detection** (don't trade on holidays)
+
+### What Was Actually Implemented
+- ⚠️  PARTIAL - Hardcoded session times (9:30-16:00)
+- ❌ No CME calendar
+- ❌ No dynamic session detection
+- ❌ No holiday awareness
+
+### Impact
+- **MEDIUM** - Strategies use wrong session times
+- May trade when market is closed
+- Risk limits not session-aware
+
+### Status
+🟡 **PARTIALLY IMPLEMENTED** (hardcoded times only)
+
+---
+
+## ❌ **MISSING: Emergency Controls**
+
+### What Was Designed
+- **Emergency flatten** button/command
+- **Kill switch** to stop all trading immediately
+- **Position reconciliation** on restart
+- **Safe shutdown** sequence
+
+### What Was Actually Implemented
+- ❌ No emergency flatten
+- ❌ No kill switch
+- ❌ No reconciliation
+- ❌ No safe shutdown
+
+### Impact
+- **CRITICAL** - Cannot stop runaway strategies
+- No way to flatten positions in emergency
+- Dangerous for live trading
+
+### Status
+🔴 **NOT IMPLEMENTED**
+
+---
+
+## ⚠️  **PARTIAL: Performance Monitoring**
+
+### What Was Designed
+- **Latency tracking** (OnBarUpdate, risk validation, order submission)
+- **Performance counters** (bars/second, orders/second)
+- **Performance alerting** (when latency exceeds thresholds)
+- **Performance reporting** (daily performance summary)
+
+### What Was Actually Implemented
+- ✅ Performance benchmarks exist in test suite
+- ❌ No runtime latency tracking
+- ❌ No performance counters
+- ❌ No alerting
+- ❌ No reporting
+
+### Impact
+- **MEDIUM** - Cannot monitor production performance
+- Cannot detect performance degradation
+- No visibility into system throughput
+
+### Status
+🟡 **PARTIALLY IMPLEMENTED** (tests only, not production)
+
+---
+
+## ⚠️  **PARTIAL: Error Recovery**
+
+### What Was Designed
+- **Connection loss recovery** (reconnect with exponential backoff)
+- **Order state synchronization** after disconnect
+- **Graceful degradation** (continue with reduced functionality)
+- **Circuit breakers** (halt trading on repeated errors)
+
+### What Was Actually Implemented
+- ❌ No connection recovery
+- ❌ No state synchronization
+- ❌ No graceful degradation
+- ❌ No circuit breakers
+
+### Impact
+- **CRITICAL** - System fails permanently on connection loss
+- No automatic recovery
+- Dangerous for production
+
+### Status
+🔴 **NOT IMPLEMENTED**
+
+---
+
+## ✅ **IMPLEMENTED: Core Trading Features**
+
+### What Works Well
+- ✅ Order state machine (complete)
+- ✅ Multi-tier risk management (complete)
+- ✅ Position sizing (complete)
+- ✅ Confluence scoring (complete)
+- ✅ Regime detection (complete)
+- ✅ Analytics & reporting (complete)
+- ✅ NT8 integration (basic - compiles and runs)

+
+---
+
+## 🎯 Recommended Implementation Order
+
+### **Phase 1: Critical Safety Features (P0) - 6-8 hours**
+
+**Must have before ANY live trading:**
+
+1. **Debug Logging Toggle** (1 hour)
+   - Add `EnableDebugLogging` property
+   - Add conditional logging throughout
+   - Add log level configuration
+
+2. **Emergency Flatten** (2 hours)
+   - Add emergency flatten method
+   - Add kill switch property
+   - Add to UI as parameter
+
+3. **Error Recovery** (3-4 hours)
+   - Connection loss detection
+   - Reconnect logic
+   - State synchronization
+   - Circuit breakers
+
+---
+
+### **Phase 2: Operations & Debugging (P1) - 4-6 hours**
+
+**Makes debugging and operations possible:**
+
+1. **Configuration Export/Import** (2 hours)
+   - Export to JSON
+   - Import from JSON
+   - Validation on load
+
+2. **Health Check System** (2-3 hours)
+   - Component status checks
+   - Performance metrics
+   - Alert thresholds
+
+3. **Enhanced Logging** (1 hour)
+   - Log levels
+   - Structured logging
+   - Correlation IDs
+
+---
+
+### **Phase 3: Production Polish (P2-P3) - 4-6 hours**
+
+**Nice to have for production:**
+
+1. **Session Management** (2 hours)
+   - CME calendar
+   - Dynamic session detection
+
+2. **Performance Monitoring** (2 hours)
+   - Runtime latency tracking
+   - Performance counters
+   - Daily reports
+
+3. **Config Validation** (1-2 hours)
+   - Cross-parameter validation
+   - Dependency checks
+   - Startup validation
+
+---
+
+## 💡 Why This Happened
+
+Looking at the timeline:
+1. **Phases 0-5** focused on core trading logic (correctly)
+2. **NT8 Integration (Phases A-C)** rushed to get it working
+3. **Production readiness features** were designed but deferred
+4. **Zero trades issue** exposed the gap (no debugging capability)
+
+**This is actually NORMAL and GOOD:**
+- ✅ Got the hard part (trading logic) right first
+- ✅ Integration is working (compiles, loads, initializes)
+- ⚠️  Now need production hardening before live trading
+
+---
+
+## ✅ Action Plan
+
+### **Immediate (Right Now)**
+
+Hand Kilocode **TWO CRITICAL SPECS:**
+
+1. **`DEBUG_LOGGING_SPEC.md`** - Add debug toggle and enhanced logging
+2. **`DIAGNOSTIC_LOGGING_SPEC.md`** (already created) - Add verbose output
+
+**Time:** 2-3 hours for Kilocode to implement both
+
+**Result:** You'll be able to see what's happening and debug the zero trades issue
+
+---
+
+### **This Week**
+
+After debugging zero trades:
+
+3. **`EMERGENCY_CONTROLS_SPEC.md`** - Emergency flatten, kill switch
+4. **`ERROR_RECOVERY_SPEC.md`** - Connection recovery, circuit breakers
+
+**Time:** 6-8 hours
+
+**Result:** Safe for extended simulation testing
+
+---
+
+### **Next Week**
+
+5. **`CONFIG_EXPORT_SPEC.md`** - JSON export/import
+6. **`HEALTH_CHECK_SPEC.md`** - System monitoring
+
+**Time:** 4-6 hours
+
+**Result:** Ready for production deployment planning
+
+---
+
+## 🎉 Silver Lining
+
+**The GOOD news:**
+- ✅ Core trading engine is rock-solid (240+ tests, all passing)
+- ✅ NT8 integration fundamentals work (compiles, loads, initializes)
+- ✅ Architecture is sound (adding these features won't require redesign)
+
+**The WORK:**
+- 🔴 ~15-20 hours of production hardening features remain
+- 🔴 Most are straightforward to implement
+- 🔴 All are well-designed (specs exist or are easy to create)
+
+---
+
+## 📋 **What to Do Next**
+
+**Option A: Debug First (Recommended)**
+1. Give Kilocode the diagnostic logging spec
+2. Get zero trades issue fixed
+3. Then implement safety features
+
+**Option B: Safety First**
+1. Implement emergency controls and error recovery
+2. Then debug zero trades with safety net in place
+
+**My Recommendation:** **Option A** - fix zero trades first so you can validate the core logic works, THEN add safety features before extended testing.
+
+---
+
+**You were 100% right to call this out. These gaps need to be filled before production trading.**
+
+Want me to create the specs for the critical missing features?

+# NT8 Strategy Diagnostic Logging Enhancement
+
+**For:** Kilocode AI Agent  
+**Priority:** HIGH  
+**Mode:** Code Mode  
+**Estimated Time:** 30-40 minutes  
+**Files to Edit:** 1 file (NT8StrategyBase.cs)  
+
+---
+
+## 🎯 Objective
+
+Add comprehensive diagnostic logging to NT8StrategyBase so we can see exactly
+what's happening during backtesting when zero trades occur. This will help
+diagnose if the issue is:
+- Strategy not generating intents
+- Risk manager rejecting trades
+- Position sizer issues
+- Data feed issues
+
+---
+
+## 🔧 Changes to NT8StrategyBase.cs
+
+### Change 1: Enhanced OnBarUpdate logging
+
+**Find:**
+```csharp
+        protected override void OnBarUpdate()

+# NT8 Strategy Dropdown Fix Specification
+
+**For:** Kilocode AI Agent  
+**Priority:** URGENT  
+**Mode:** Code Mode  
+**Estimated Time:** 20-30 minutes  
+**Files to Edit:** 1 file (SimpleORBNT8.cs)  
+
+---
+
+## 🎯 Objective
+
+Fix SimpleORBNT8 not appearing in NT8 strategy dropdown. The strategy compiles
+but causes a runtime error when NT8 tries to load it for the dropdown list.
+
+---
+
+## 🔍 Root Cause
+
+`ConfigureStrategyParameters()` is called during `State.DataLoaded` and accesses
+`Instrument.MasterInstrument.PointValue` and `Instrument.MasterInstrument.TickSize`.
+
+These properties are only safely available when the strategy is applied to a chart
+with a known instrument. When NT8 loads the strategy list for the dropdown,
+`Instrument` is null, causing a NullReferenceException that removes the strategy
+from the available list silently.
+
+Per NT8 forum: "If there is an error in OnStateChange() when you go to
+New > Strategy, the OnStateChange() is called and a run-time type error
+can occur which removes the strategy from the available list as a preventative measure."
+
+---
+
+## 🔧 Fix: SimpleORBNT8.cs - Guard Instrument access
+
+### File
+`src/NT8.Adapters/Strategies/SimpleORBNT8.cs`
+
+### Change: Add null guard in ConfigureStrategyParameters()
+
+**Find:**

+# Fix Git Authentication Issues
+
+## Problem
+Git credentials expire after a few hours, causing `Authentication failed` errors.
+
+---
+
+## Quick Fix Options
+
+### Option 1: Re-authenticate (Immediate)
+
+```powershell
+# Push and enter credentials when prompted
+git push
+
+# Enter your Gitea username and password/token when prompted
+```
+
+---
+
+### Option 2: Update Credential Helper (Permanent Fix)
+
+```powershell
+# Set credential helper to store credentials permanently
+git config --global credential.helper store
+
+# Or use Windows Credential Manager (recommended for Windows)
+git config --global credential.helper wincred
+
+# Or use manager-core (modern credential manager)
+git config --global credential.helper manager-core
+
+# Then push - it will ask for credentials ONE TIME and remember
+git push
+```
+
+After running one of these, the next `git push` will prompt for credentials **once** and then remember them.
+
+---
+
+### Option 3: Use SSH Instead of HTTPS (Best Long-term)
+
+This eliminates password prompts entirely.
+
+**Step 1: Generate SSH Key**
+```powershell
+# Generate new SSH key
+ssh-keygen -t ed25519 -C "your-email@example.com"
+
+# Press Enter to accept default location: C:\Users\YourName\.ssh\id_ed25519
+# Enter a passphrase (or press Enter for no passphrase)
+```
+
+**Step 2: Copy Public Key**
+```powershell
+# Display your public key
+cat ~/.ssh/id_ed25519.pub
+
+# Or copy to clipboard
+clip < ~/.ssh/id_ed25519.pub
+```
+
+**Step 3: Add to Gitea**
+1. Go to https://git.thehussains.org
+2. User Settings → SSH/GPG Keys → Add Key
+3. Paste your public key
+4. Save
+
+**Step 4: Update Remote URL**
+```powershell
+cd C:\dev\nt8-sdk
+
+# Check current remote
+git remote -v
+
+# Change from HTTPS to SSH
+git remote set-url origin git@git.thehussains.org:mo/nt8-sdk.git
+
+# Verify change
+git remote -v
+
+# Now push with SSH (no password needed)
+git push
+```
+
+---
+
+### Option 4: Use Personal Access Token
+
+**Step 1: Create Token in Gitea**
+1. Go to https://git.thehussains.org
+2. User Settings → Applications → Generate New Token
+3. Name it "NT8-SDK-Development"
+4. Select scopes: `repo` (full control)
+5. Generate and **COPY THE TOKEN** (you won't see it again)
+
+**Step 2: Use Token as Password**
+```powershell
+# When prompted for password, paste the token instead
+git push
+
+# Username: mo
+# Password: [paste your token here]
+```
+
+**Step 3: Store Token Permanently**
+```powershell
+# Configure credential helper
+git config --global credential.helper store
+
+# Push once with token
+git push
+
+# Enter username and token when prompted
+# Future pushes won't require credentials
+```
+
+---
+
+## Recommended Solution
+
+**For now (immediate):** Use Option 2
+```powershell
+git config --global credential.helper manager-core
+git push
+# Enter credentials once, will be remembered
+```
+
+**For best security:** Use Option 3 (SSH keys)
+- No passwords to remember
+- More secure
+- Works across all Git operations
+- One-time setup
+
+---
+
+## Current Status - What to Do Now
+
+**Immediate action:**
+```powershell
+# Quick fix - store credentials
+git config --global credential.helper store
+
+# Push with credentials
+git push
+
+# Enter your Gitea username and password
+# Credentials will be stored for future use
+```
+
+---
+
+## Verify Credential Helper
+
+```powershell
+# Check what credential helper is configured
+git config --global credential.helper
+
+# Should show one of:
+# - store
+# - wincred
+# - manager-core
+```
+
+---
+
+## Troubleshooting
+
+**If credentials still don't work:**
+
+```powershell
+# Clear existing credentials
+git credential reject <<EOF
+protocol=https
+host=git.thehussains.org
+EOF
+
+# Try push again with fresh credentials
+git push
+```
+
+**If using 2FA on Gitea:**
+- You MUST use a Personal Access Token, not your password
+- See Option 4 above
+
+---
+
+## After Fixing Auth
+
+Once authentication is working, continue with the Phase 5 commit:
+
+```powershell
+# Verify you can access remote
+git fetch
+
+# Push your commits
+git push
+
+# Should succeed without authentication errors
+```
+
+---
+
+**Recommended: Run Option 2 now, then switch to SSH (Option 3) when you have time.**

+
+## Verification After Commit
+
+```bash
+# Verify commit was created

+
+## Pre-Commit Checklist
+
+Before committing, verify:
+
+- [ ] All 240+ tests passing: `dotnet test`
+- [ ] Build succeeds: `dotnet build --configuration Release`
+- [ ] No new warnings: `.\verify-build.bat`
+- [ ] Analytics directory contains 15 .cs files
+- [ ] Tests directory contains 5 analytics test files
+- [ ] Phase5IntegrationTests.cs exists
+- [ ] Documentation files updated
+
+---
+
+## Rollback If Needed
+
+If something goes wrong:
+
+```bash
+# Undo last commit (keep changes)
+git reset --soft HEAD~1
+
+# Undo last commit (discard changes) - USE WITH CAUTION
+git reset --hard HEAD~1
+
+# Unstage specific file
+git restore --staged <filename>
+```
+
+---
+
+## Recommended Approach
+
+**I recommend Option 2 (Stage Directories)** because:
+- ✅ Captures all Phase 5 files automatically
+- ✅ Safer than `git add -A` (won't stage unrelated files)
+- ✅ Simpler than listing 26 individual files
+- ✅ Easy to review with `git status` before committing
+
+---
+
+**Ready to commit!** Run Option 2 commands and Phase 5 will be properly committed with all source code, tests, and documentation.

+
+## TASK-01 — Kill Switch + Verbose Logging
+
+**File being modified:** `src/NT8.Adapters/Strategies/NT8StrategyBase.cs`
+**Spec file:** `TASK-01-kill-switch.md`
+
+### Kilocode Prompt
+
+Paste this into Kilocode chat verbatim:
+
+```
+Please implement TASK-01 from TASK-01-kill-switch.md
+
+Summary of what you need to do:
+1. Add two NinjaScript properties to NT8StrategyBase: EnableKillSwitch (bool) and EnableVerboseLogging (bool)
+2. Add private field: _killSwitchTriggered
+3. Set defaults in OnStateChange → State.SetDefaults
+4. Add kill switch check as the VERY FIRST thing in OnBarUpdate() — before all other guards
+5. Wrap Print calls inside ProcessStrategyIntent() with `if (EnableVerboseLogging)`
+
+Important constraints:
+- C# 5.0 only — use string.Format(), not $""
+- Do NOT use ?. null conditional operator  
+- Do NOT change constructor, InitializeSdkComponents(), or SubmitOrderToNT8()
+- After every file change, run verify-build.bat mentally (I will run it to verify)
+
+When done, tell me exactly what lines you added/changed and confirm the acceptance criteria from the task file are met.
+```
+
+### After Kilocode Responds
+
+1. **Review the diff** — confirm:
+   - `EnableKillSwitch` and `EnableVerboseLogging` are `[NinjaScriptProperty]` decorated
+   - Kill switch check is the FIRST thing in `OnBarUpdate()` before `_sdkInitialized` check
+   - No `$""` string interpolation introduced
+   - No other files were modified
+
+2. **Run verify-build:**
+   ```
+   Ctrl+Shift+B
+   ```
+   ✅ Must pass before proceeding
+
+3. **If verify-build fails:** Paste the error output back to Kilocode:
+   ```
+   verify-build.bat failed with these errors:
+   [paste errors]
+   Please fix them. Remember C# 5.0 only — no string interpolation, no ?. operator.
+   ```
+
+4. **Run tests:**
+   ```
+   Ctrl+Shift+P → Run Task → test-all
+   ```
+   ✅ All 240+ tests must still pass

+
+## TASK-02 — Wire ExecutionCircuitBreaker
+
+**File being modified:** `src/NT8.Adapters/Strategies/NT8StrategyBase.cs`
+**Spec file:** `TASK-02-circuit-breaker.md`
+**Depends on:** TASK-01 must be complete
+
+### Kilocode Prompt
+
+```
+TASK-01 is complete. Now please implement TASK-02 from TASK-02-circuit-breaker.md
+
+Summary:
+1. Add using statements: NT8.Core.Execution and Microsoft.Extensions.Logging.Abstractions
+2. Add private field: _circuitBreaker (type ExecutionCircuitBreaker)
+3. Instantiate in InitializeSdkComponents() after _positionSizer is created:
+   _circuitBreaker = new ExecutionCircuitBreaker(NullLogger<ExecutionCircuitBreaker>.Instance, failureThreshold: 3, timeout: TimeSpan.FromSeconds(30));
+4. Add circuit breaker gate at the TOP of SubmitOrderToNT8() — if ShouldAllowOrder() returns false, Print a message and return
+5. After successful submission, call _circuitBreaker.OnSuccess()
+6. In the catch block, call _circuitBreaker.OnFailure()
+7. In OnOrderUpdate(), when orderState == OrderState.Rejected, call _circuitBreaker.RecordOrderRejection(reason)
+
+Constraints:
+- C# 5.0 only
+- Do NOT modify ExecutionCircuitBreaker.cs — it is already correct
+- Do NOT modify any Core layer files
+- Do NOT modify any test files
+
+When done, confirm all acceptance criteria from TASK-02-circuit-breaker.md are met.
+```
+
+### Verification
+
+1. **Check the diff:**
+   - `_circuitBreaker` field exists
+   - `SubmitOrderToNT8()` has the `ShouldAllowOrder()` gate at the top
+   - `OnOrderUpdate()` calls `RecordOrderRejection()` on rejected state
+   - `ExecutionCircuitBreaker.cs` was NOT touched

+
+```
+Please implement TASK-03 from TASK-03-trailing-stop.md
+
+Summary:
+1. Open src/NT8.Core/Execution/TrailingStopManager.cs
+2. Find CalculateNewStopPrice() — it currently has broken/placeholder math
+3. Update the signature to add a TrailingStopConfig config parameter
+4. Replace the switch body with real calculations:
+   - FixedTrailing: marketPrice ± (config.TrailingAmountTicks * 0.25m)
+   - ATRTrailing: marketPrice ± (config.AtrMultiplier * estimatedAtr) where estimatedAtr = position.AverageFillPrice * 0.005m
+   - Chandelier: same formula as ATRTrailing but default multiplier 3.0
+   - Use position.Side to determine + vs - (Buy = subtract from price, Sell = add to price)
+5. Fix the ONE call site inside UpdateTrailingStop() to pass trailingStop.Config
+6. Create tests/NT8.Core.Tests/Execution/TrailingStopManagerFixedTests.cs with unit tests verifying:
+   - Long FixedTrailing 8 ticks at price 5100 → stop = 5098.0
+   - Short FixedTrailing 8 ticks at price 5100 → stop = 5102.0
+
+Constraints:
+- C# 5.0 only
+- Check the actual field names in TrailingStopConfig before using them — do not assume
+- Do NOT change the class structure, just the CalculateNewStopPrice() method and its call site
+
+When done, confirm acceptance criteria from TASK-03-trailing-stop.md are met.
+```
+
+### Verification
+
+1. **Check the diff:**
+   - `CalculateNewStopPrice` has new `config` parameter

+
+### Kilocode Prompt
+
+```
+Please implement TASK-04 from TASK-04-log-level.md
+
+Summary:
+1. First, check if a LogLevel enum already exists in the project (search for "enum LogLevel")
+2. If not, add LogLevel enum: Debug=0, Information=1, Warning=2, Error=3, Critical=4
+3. Add MinimumLevel property (type LogLevel, default Information) to BasicLogger
+4. Update the private WriteLog() helper to accept a LogLevel and return early if below MinimumLevel
+5. Update each public log method (LogDebug, LogInformation, etc.) to pass its level to WriteLog()
+
+Constraints:
+- C# 5.0 only
+- Default must be Information (backward compatible — existing behavior unchanged at default)
+- Do NOT change the ILogger interface signature
+- Do NOT break any existing tests that depend on specific log output
+
+When done, confirm acceptance criteria from TASK-04-log-level.md are met.
+```

+2. Add private static bool IsCmeHoliday(DateTime utcTime) helper that converts to Eastern time and checks the set
+3. Update IsRegularTradingHours() to call IsCmeHoliday(time) first — return false if it is a holiday
+
+Constraints:
+- C# 5.0 — use new HashSet<DateTime> { ... } initializer syntax (this works in C# 5)
+- Wrap the TimeZoneInfo.ConvertTimeFromUtc() call in try/catch — return false on exception

+
+## Troubleshooting Kilocode
+
+### If Kilocode introduces C# 6+ syntax
+
+Paste this correction:
+```
+Build failed with C# syntax errors. You used C# 6+ features which are not allowed.
+This project targets C# 5.0 / .NET Framework 4.8.
+
+Please fix:
+- Replace any $"..." with string.Format("...", ...)
+- Replace ?. with explicit null checks: if (x != null) x.Method()
+- Replace => on properties/methods with standard { get { return ...; } } syntax
+- Replace nameof() with string literals
+- Replace out var with two-step: declare variable, then call with out
+
+Then re-run verify-build.bat to confirm.
+```
+
+### If Kilocode modifies the wrong file
+
+```
+You modified [filename] which is in the "Do NOT Change" list.
+Please revert those changes and only modify the files listed in the task spec.
+The Core layer is complete and tested — changes there break 240+ tests.
+```
+
+### If tests fail after a task
+
+```
+Tests failed after your changes. Please:
+1. Run: dotnet test NT8-SDK.sln --verbosity normal 2>&1 | head -50
+2. Show me the first failing test and its error message
+3. Fix only the failing tests without introducing new changes to passing test files
+```
+
+### If Kilocode is unsure about a field name or method signature
+
+```
+Before assuming a field name, please read the actual file first:
+[specify file path]
+Confirm the exact field/method names before writing code.
+```
+

+### Why This Architecture?
+
+1. **NT8StrategyBase deployed as .cs file** - NT8 must compile it to access platform APIs
+2. **NT8ExecutionAdapter in DLL** - Reusable adapter logic, testable
+3. **Core SDK in DLL** - All business logic stays in tested, versioned SDK

+**Goal:** Optimize parameters to improve profitability and reduce drawdown  
+
+---
+
+## 📊 Current Baseline Performance
+
+### Trade Statistics (5 trades, Feb 10-16, 2026)
+- **Net Profit:** $320
+- **Profit Factor:** 3.00
+- **Win Rate:** 60% (3W/2L)
+- **Avg Win:** $160
+- **Avg Loss:** $80
+- **Win/Loss Ratio:** 2:1
+- **Sharpe Ratio:** 1.31
+- **Max Drawdown:** $160
+
+### Performance by Direction
+**Longs (2 trades):**
+- Win Rate: 100%
+- Profit: $320
+- Profit Factor: 99.0
+- Sharpe: 2.30
+
+**Shorts (3 trades):**
+- Win Rate: 33%
+- Profit: $0
+- Profit Factor: 1.00
+- Sharpe: 1.53
+
+**KEY INSIGHT:** Longs are exceptional, shorts are break-even/losing.
+
+---
+
+## 🎯 Optimization Priority List
+
+### Priority 1: Direction Filter (CRITICAL)
+**Current:** Trading both long and short
+**Issue:** Shorts have 33% win rate vs 100% for longs
+**Action:** Test long-only mode
+
+**Expected Impact:**
+- Net profit: Increase (eliminate losing shorts)
+- Win rate: Increase to 100%
+- Drawdown: Decrease significantly
+
+---
+
+### Priority 2: Opening Range Period
+**Current:** 30 minutes
+**Range to Test:** 15, 20, 30, 45, 60 minutes
+
+**Hypothesis:** 
+- Shorter OR (15-20 min): More trades, potentially more false breakouts
+- Longer OR (45-60 min): Fewer trades, higher quality setups
+
+**Metric to Watch:** Profit factor, win rate
+
+---
+
+### Priority 3: Stop Loss / Profit Target
+**Current:** Stop 8 ticks, Target 16 ticks (2:1 R:R)
+
+**Test Matrix:**
+| Stop | Target | R:R | Rationale |
+|------|--------|-----|-----------|
+| 6 | 12 | 2:1 | Tighter, less heat |
+| 8 | 16 | 2:1 | Current baseline |
+| 10 | 20 | 2:1 | Wider, more room |
+| 8 | 24 | 3:1 | Asymmetric, bigger winners |
+| 10 | 30 | 3:1 | Wide asymmetric |
+
+**Metric to Watch:** Win rate vs avg win/loss ratio tradeoff
+
+---
+
+### Priority 4: Entry Threshold (Std Dev Multiplier)
+**Current:** 1.0 (breakout = 1x standard deviation)
+
+**Range to Test:** 0.5, 1.0, 1.5, 2.0
+
+**Hypothesis:**
+- Lower (0.5): More entries, lower quality
+- Higher (1.5-2.0): Fewer entries, higher conviction
+
+**Metric to Watch:** Trade frequency vs win rate
+
+---
+
+### Priority 5: Time-of-Day Filter
+**Current:** Trading all day (9:30-16:00)
+
+**Test Scenarios:**
+- First hour only (9:30-10:30)
+- Morning session (9:30-12:00)
+- Afternoon only (12:00-16:00)
+- First 2 hours (9:30-11:30)
+
+**Hypothesis:** Early breakouts (first hour) might have more momentum
+
+**Metric to Watch:** Win rate by time of entry
+
+---
+
+## 📋 Optimization Test Plan
+
+### Phase 1: Quick Wins (30 minutes)
+**Test long-only mode immediately**
+
+1. Add property to SimpleORBNT8:
+```csharp
+[NinjaScriptProperty]
+[Display(Name = "Long Only", GroupName = "ORB Strategy", Order = 10)]
+public bool LongOnly { get; set; }
+```
+
+2. Update intent processing in base class to filter shorts if LongOnly = true
+
+3. Re-run backtest with LongOnly = true
+
+**Expected:** Profit increases, drawdown decreases
+
+---
+
+### Phase 2: Parameter Grid Search (2-3 hours)
+
+Use NT8 Strategy Analyzer Optimization:
+
+**Variables to Optimize:**
+1. Opening Range Minutes: 15, 20, 30, 45, 60
+2. Stop Ticks: 6, 8, 10, 12
+3. Target Ticks: 12, 16, 20, 24, 30
+4. Std Dev Multiplier: 0.5, 1.0, 1.5, 2.0
+5. Long Only: true, false
+
+**Optimization Metric:** Net Profit or Sharpe Ratio
+
+**Total Combinations:** 5 × 4 × 5 × 4 × 2 = 800 tests
+**Reduce to:** Test in stages to avoid combinatorial explosion
+
+---
+
+### Phase 3: Walk-Forward Analysis (4-6 hours)
+
+**Process:**
+1. Split data: Train on Jan-Feb, Test on Mar-Apr
+2. Optimize on training set
+3. Validate on test set (out-of-sample)
+4. Check for overfitting
+
+**Goal:** Ensure parameters aren't curve-fit to specific market conditions
+
+---
+
+### Phase 4: Regime-Aware Optimization (Future)
+
+Use existing regime detection:
+- Optimize separately for High Vol vs Low Vol regimes
+- Different parameters for Trending vs Mean-Reverting
+- Grade-based position sizing (already implemented)
+
+---
+
+## 🔧 NT8 Strategy Analyzer Optimization Settings
+
+### How to Run Optimization in NT8:
+
+1. **Open Strategy Analyzer**

+   - Target Ticks: Start 12, Stop 30, Step 4
+   - Std Dev Multiplier: Start 0.5, Stop 2.0, Step 0.5
+
+5. **Optimization Target:** 
+   - Primary: Net Profit
+   - Secondary: Sharpe Ratio (to avoid overfitting)
+
+6. **Click "Run"**
+7. **Review results** - sort by Sharpe Ratio (not just profit)
+
+---
+
+## 📊 What to Look For in Results

+- ❌ Win rate > 90% (unrealistic)
+- ❌ Sharpe > 5.0 (too good to be true)
+- ❌ Only 1-2 trades (not statistically significant)
+- ❌ Max drawdown = $0 (lucky parameters)
+
+### Good Signs (Robust):
+- ✅ Win rate 55-70%
+- ✅ Sharpe 1.5-3.0
+- ✅ 10+ trades (statistical significance)
+- ✅ Profit factor 1.5-3.0
+- ✅ Consistent across similar parameters
+
+---
+
+## 🎯 Expected Optimal Results
+
+Based on current performance, after optimization expect:
+
+**Conservative Estimate:**
+- Net Profit: $400-600 (vs $320 baseline)
+- Win Rate: 65-75%
+- Profit Factor: 2.5-4.0
+- Sharpe: 1.5-2.5
+- Max Drawdown: <$200
+
+**Stretch Goal:**
+- Net Profit: $800+
+- Win Rate: 70-80%
+- Profit Factor: 3.5-5.0
+- Sharpe: 2.5-3.5

+- CS1998 warnings in test mock files
+- These existed before Phases A-C
+- No new warnings were added
+- Safe to proceed
+
+### NT8 Strategy Compilation
+**Important:** The strategy .cs files:
+- Are **not compiled** into NT8.Adapters.dll
+- Are deployed as **source files** to NT8
+- Must be compiled **by NinjaTrader 8**
+- This is by design (required for NT8 integration)
+
+### First-Time NT8 Compilation
+**Potential Issues:**
+- Missing NT8 DLL references (should auto-resolve)
+- Strategy namespace conflicts (none expected)
+- C# version mismatch (validated as C# 5.0 compatible)
+
+**If Issues Occur:**
+1. Check NT8 version (8.0.20.1+)
+2. Verify .NET Framework 4.8 installed
+3. Review NinjaScript Editor error messages
+4. Consult TROUBLESHOOTING.md in deployment guide

+# Post NT8 Integration Roadmap - Next Steps
+
+**Scenario:** Phases A, B, C Complete Successfully  
+**Current State:** NT8 SDK fully integrated, compiles in NT8, basic testing done  
+**Project Completion:** ~90%  
+**Date:** February 2026
+
+---
+
+## 🎯 Immediate Next Steps (Week 1-2)
+
+### Step 1: NT8 Simulation Validation (3-5 days)
+**Priority:** CRITICAL - Must validate before any live trading  
+**Goal:** Prove the integration works correctly in NT8 simulation environment
+
+#### Day 1: MinimalTestStrategy Validation
+**Actions:**
+1. Deploy to NT8 using `Deploy-To-NT8.ps1`
+2. Open NT8, compile in NinjaScript Editor
+3. Enable MinimalTestStrategy on ES 5-minute chart
+4. Let run for 4 hours
+5. Verify:
+   - No crashes
+   - Bars logging correctly
+   - No memory leaks
+   - Clean termination
+
+**Success Criteria:**
+- [ ] Compiles with zero errors
+- [ ] Runs 4+ hours without crashes
+- [ ] Logs every 10th bar correctly
+- [ ] Clean startup/shutdown
+
+---
+
+#### Day 2-3: SimpleORBNT8 Historical Data Testing
+**Actions:**
+1. Enable SimpleORBNT8 on ES 5-minute chart
+2. Configure parameters:
+   - OpeningRangeMinutes: 30
+   - StopTicks: 8
+   - TargetTicks: 16
+   - DailyLossLimit: 1000
+3. Run on historical data (replay):
+   - Load 1 week of data
+   - Enable strategy
+   - Let run through entire week
+4. Monitor Output window for:
+   - SDK initialization messages
+   - Opening range calculation
+   - Trade intent generation
+   - Risk validation messages
+   - Order submission logs
+
+**Validation Checklist:**
+- [ ] SDK components initialize without errors
+- [ ] Opening range calculates correctly
+- [ ] Strategy generates trading intents appropriately
+- [ ] Risk manager validates trades
+- [ ] Position sizer calculates contracts correctly
+- [ ] No exceptions or errors in 1 week of data
+- [ ] Performance <200ms per bar (check with Print timestamps)
+
+**Expected Issues to Watch For:**
+- Opening range calculation on session boundaries
+- Risk limits triggering correctly
+- Position sizing edge cases (very small/large stops)
+- Memory usage over extended runs
+
+---
+
+#### Day 4-5: SimpleORBNT8 Simulation Account Testing
+**Actions:**

+
+4. **Enable Strategy:**
+   - Check "Enabled" box
+   - Click "OK"
+
+5. **Watch Output Window:**
+   ```
+   [SDK] Simple ORB NT8 initialized successfully
+   [SDK] SDK initialization complete
+   [SDK] Submitting: Buy 1 ES
+   [SDK] Filled: SDK_ES_... @ 4203.50
+   ```
+
+6. **Verify on Chart:**
+   - Should see entry markers
+   - Stop loss lines
+   - Target lines
+   - Position indicators
+
+**Success:** If SDK initializes and strategy generates trades, full integration works! ✅
+
+---
+
+### Step 5: Test SimpleORBNT8 - Simulation Account (10+ minutes)
+
+**Purpose:** Verify live order submission works
+
+1. **Connect to Simulation:**

+   - Click "OK"
+
+5. **Monitor Live:**
+   - Watch for opening range calculation (first 30 minutes)
+   - Look for trade signals
+   - Verify orders appear in "Strategies" tab
+   - Check "Orders" tab for fills
+
+6. **Validate:**
+   - [ ] SDK initializes without errors
+   - [ ] Opening range calculates correctly
+   - [ ] Strategy generates intents when appropriate
+   - [ ] Orders submit to simulation account
+   - [ ] Stops and targets placed correctly
+   - [ ] No exceptions in Output window
+
+**Success:** If orders submit and fill in simulation, ready for extended testing! ✅

+# RTH Session Filter - Quick Fix Specification
+
+**For:** Kilocode AI Agent  
+**Priority:** URGENT  
+**Mode:** Code Mode  
+**Estimated Time:** 15-20 minutes  
+**Files to Edit:** 1 file (NT8StrategyBase.cs)
+
+---
+
+## 🎯 Objective
+
+Add session time filter to prevent trading during extended hours (ETH).
+Only allow trades during Regular Trading Hours (RTH): 9:30 AM - 4:00 PM ET.
+
+---
+
+## 🔧 Fix: Add Session Filter to OnBarUpdate
+
+**File:** `src/NT8.Adapters/Strategies/NT8StrategyBase.cs`
+
+**Find the OnBarUpdate method** (around line 150):
+
+```csharp
+protected override void OnBarUpdate()
+{
+    if (!_sdkInitialized || _sdkStrategy == null)
+    {
+        if (CurrentBar == 0)
+            Print(string.Format("[SDK] Not initialized: sdkInit={0}, strategy={1}", 
+                _sdkInitialized, _sdkStrategy != null));
+        return;
+    }
+    
+    if (CurrentBar < BarsRequiredToTrade)
+    {
+        if (CurrentBar == 0)
+            Print(string.Format("[SDK] Waiting for bars: current={0}, required={1}", 
+                CurrentBar, BarsRequiredToTrade));
+        return;
+    }
+    
+    if (Time[0] == _lastBarTime)
+        return;
+```
+
+**Add this session filter right after the BarsRequiredToTrade check:**
+
+```csharp
+protected override void OnBarUpdate()
+{
+    if (!_sdkInitialized || _sdkStrategy == null)
+    {
+        if (CurrentBar == 0)
+            Print(string.Format("[SDK] Not initialized: sdkInit={0}, strategy={1}", 
+                _sdkInitialized, _sdkStrategy != null));
+        return;
+    }
+    
+    if (CurrentBar < BarsRequiredToTrade)
+    {
+        if (CurrentBar == 0)
+            Print(string.Format("[SDK] Waiting for bars: current={0}, required={1}", 
+                CurrentBar, BarsRequiredToTrade));
+        return;
+    }
+    
+    // NEW: Session filter - only trade during RTH (9:30 AM - 4:00 PM ET)
+    var currentTime = Time[0];
+    var hour = currentTime.Hour;
+    var minute = currentTime.Minute;
+    
+    // Convert to minutes since midnight for easier comparison
+    var currentMinutes = (hour * 60) + minute;
+    var rthStart = (9 * 60) + 30;  // 9:30 AM = 570 minutes
+    var rthEnd = (16 * 60);         // 4:00 PM = 960 minutes
+    
+    if (currentMinutes < rthStart || currentMinutes >= rthEnd)
+    {
+        // Outside RTH - skip this bar
+        if (CurrentBar == BarsRequiredToTrade)
+        {
+            Print(string.Format("[SDK] Outside RTH: {0:HH:mm} (RTH is 09:30-16:00)", currentTime));
+        }
+        return;
+    }
+    
+    if (Time[0] == _lastBarTime)
+        return;
+```
+
+---
+
+## 🎯 Alternative: Add Property to Enable/Disable RTH Filter
+
+If you want to make it configurable, add this property to the properties section:
+
+```csharp
+[NinjaScriptProperty]
+[Display(Name = "RTH Only", GroupName = "SDK", Order = 2)]
+public bool RthOnly { get; set; }
+```
+
+Then in `State.SetDefaults`:
+
+```csharp
+EnableSDK = true;
+RthOnly = true;  // Default to RTH only
+```
+
+And update the session filter:
+
+```csharp
+// Session filter - only trade during RTH if enabled
+if (RthOnly)
+{
+    var currentTime = Time[0];
+    var hour = currentTime.Hour;
+    var minute = currentTime.Minute;
+    
+    var currentMinutes = (hour * 60) + minute;
+    var rthStart = (9 * 60) + 30;  // 9:30 AM
+    var rthEnd = (16 * 60);         // 4:00 PM
+    
+    if (currentMinutes < rthStart || currentMinutes >= rthEnd)
+    {
+        if (CurrentBar == BarsRequiredToTrade)
+        {
+            Print(string.Format("[SDK] Outside RTH: {0:HH:mm} (RTH is 09:30-16:00)", currentTime));
+        }
+        return;
+    }
+}
+```
+

+
+## ✅ Verification
+
+```bash
+# Build
+dotnet build src\NT8.Adapters\NT8.Adapters.csproj --configuration Release
+
+# Deploy
+.\deployment\Deploy-To-NT8.ps1
+```
+
+**In NT8 after recompile:**
+- Run backtest again
+- Check Output window
+- Should see: `[SDK] Outside RTH: 22:15 (RTH is 09:30-16:00)`
+- Should see intents ONLY during 9:30-16:00

+# NT8 Strategy Dropdown Complete Fix
+
+**For:** Kilocode AI Agent  
+**Priority:** URGENT  
+**Mode:** Code Mode  
+**Estimated Time:** 15-20 minutes  
+**Files to Edit:** 2 files  
+
+---
+
+## 🎯 Objective
+
+Fix two issues preventing SimpleORBNT8 from appearing in NT8 strategy dropdown:
+1. NT8StrategyBase (abstract) incorrectly appears in dropdown
+2. SimpleORBNT8 has runtime error preventing it from loading
+
+---
+
+## 🔧 Fix 1: NT8StrategyBase.cs - Remove Name from abstract class
+
+### File
+`src/NT8.Adapters/Strategies/NT8StrategyBase.cs`
+
+### Problem
+Abstract base class sets `Name = "NT8 SDK Strategy Base"` which makes it
+appear in the strategy dropdown. Abstract strategies should NOT have a Name.
+
+### Change: Remove or comment out Name assignment
+
+**Find (around line 97):**
+```csharp
+        protected override void OnStateChange()
+        {
+            if (State == State.SetDefaults)
+            {
+                Description = "SDK-integrated strategy base";
+                Name = "NT8 SDK Strategy Base";
+                Calculate = Calculate.OnBarClose;
+```
+
+**Replace with:**
+```csharp
+        protected override void OnStateChange()
+        {
+            if (State == State.SetDefaults)
+            {
+                Description = "SDK-integrated strategy base";
+                // Name intentionally not set - this is an abstract base class
+                Calculate = Calculate.OnBarClose;
+```
+
+---
+
+## 🔧 Fix 2: SimpleORBNT8.cs - Guard Instrument null access
+
+### File
+`src/NT8.Adapters/Strategies/SimpleORBNT8.cs`
+
+### Problem
+`ConfigureStrategyParameters()` accesses `Instrument.MasterInstrument` which is
+null when NT8 loads the strategy for the dropdown list, causing a runtime
+exception that removes it from available strategies.
+
+### Change: Add null guard
+
+**Find:**
+```csharp
+        protected override void ConfigureStrategyParameters()
+        {
+            _strategyConfig.RiskSettings.DailyLossLimit = DailyLossLimit;
+            _strategyConfig.RiskSettings.MaxTradeRisk = MaxTradeRisk;

+
+            var pointValue = Instrument.MasterInstrument.PointValue;
+            var tickSize = Instrument.MasterInstrument.TickSize;
+            var dollarRisk = StopTicks * tickSize * pointValue;
+
+            if (dollarRisk > _strategyConfig.RiskSettings.MaxTradeRisk)
+                _strategyConfig.RiskSettings.MaxTradeRisk = dollarRisk;
+
+            _strategyConfig.SizingSettings.RiskPerTrade = RiskPerTrade;
+```
+
+**Replace with:**
+```csharp
+        protected override void ConfigureStrategyParameters()
+        {
+            _strategyConfig.RiskSettings.DailyLossLimit = DailyLossLimit;
+            _strategyConfig.RiskSettings.MaxTradeRisk = MaxTradeRisk;
+            _strategyConfig.RiskSettings.MaxOpenPositions = MaxOpenPositions;
+
+            // Guard: Instrument is null during strategy list loading
+            if (Instrument != null && Instrument.MasterInstrument != null)
+            {
+                var pointValue = Instrument.MasterInstrument.PointValue;
+                var tickSize = Instrument.MasterInstrument.TickSize;
+                var dollarRisk = StopTicks * tickSize * pointValue;

+# TASK-01: Add Kill Switch + Verbose Logging Toggle
+
+**File:** `src/NT8.Adapters/Strategies/NT8StrategyBase.cs`
+**Priority:** CRITICAL
+**Estimated time:** 45 min
+**No dependencies**
+
+---
+
+## Exact Changes Required
+
+### 1. Add two new NinjaScript properties to the `#region User-Configurable Properties` block
+
+Add these after the existing `MaxContracts` property:
+
+```csharp
+[NinjaScriptProperty]
+[Display(Name = "Kill Switch (Flatten + Stop)", GroupName = "Emergency Controls", Order = 1)]
+public bool EnableKillSwitch { get; set; }
+
+[NinjaScriptProperty]
+[Display(Name = "Verbose Logging", GroupName = "Debug", Order = 1)]
+public bool EnableVerboseLogging { get; set; }
+```
+
+### 2. Add a private field near the other private fields at the top of the class
+
+```csharp
+private bool _killSwitchTriggered;
+```
+
+### 3. Set defaults in `OnStateChange` → `State.SetDefaults` block, after the existing defaults
+
+```csharp
+EnableKillSwitch = false;
+EnableVerboseLogging = false;
+_killSwitchTriggered = false;
+```
+
+### 4. Add kill switch check at the TOP of `OnBarUpdate()`, before EVERYTHING else
+
+The very first lines of `OnBarUpdate()` must become:
+
+```csharp
+protected override void OnBarUpdate()
+{
+    // Kill switch check — must be first
+    if (EnableKillSwitch)
+    {
+        if (!_killSwitchTriggered)
+        {
+            _killSwitchTriggered = true;
+            Print(string.Format("[SDK] KILL SWITCH ACTIVATED at {0} — flattening all positions.", Time[0]));
+            try
+            {
+                ExitLong("KillSwitch");
+                ExitShort("KillSwitch");
+            }
+            catch (Exception ex)
+            {
+                Print(string.Format("[SDK] Kill switch flatten error: {0}", ex.Message));
+            }
+        }
+        return;
+    }
+
+    // Existing guards follow unchanged
+    if (!_sdkInitialized || _sdkStrategy == null)
+    { ... }
+    ...
+```
+
+### 5. Add verbose logging to `ProcessStrategyIntent()` — wrap existing Print calls
+
+Replace the existing bare `Print(...)` calls in `ProcessStrategyIntent()` with guarded versions:
+
+```csharp
+// Change every Print(...) inside ProcessStrategyIntent() to:
+if (EnableVerboseLogging)
+    Print(string.Format("...existing message..."));
+```
+
+The `Print` call that shows the intent being generated in `OnBarUpdate` (not in `ProcessStrategyIntent`) should remain unguarded — that one is important.
+
+---
+
+## Acceptance Criteria
+
+- [ ] `EnableKillSwitch` visible in NT8 strategy parameter dialog under "Emergency Controls"
+- [ ] `EnableVerboseLogging` visible under "Debug"
+- [ ] Setting `EnableKillSwitch = true` mid-run causes `ExitLong("KillSwitch")` and `ExitShort("KillSwitch")` on next bar
+- [ ] After kill switch triggers, every subsequent bar returns immediately (no strategy logic runs)
+- [ ] `verify-build.bat` passes with zero errors

+# TASK-02: Wire ExecutionCircuitBreaker into NT8StrategyBase
+
+**File:** `src/NT8.Adapters/Strategies/NT8StrategyBase.cs`
+**Priority:** CRITICAL
+**Depends on:** TASK-01 must be done first (file already open/modified)
+**Estimated time:** 45 min
+
+---
+
+## Background
+
+`ExecutionCircuitBreaker` at `src/NT8.Core/Execution/ExecutionCircuitBreaker.cs` is complete and tested.
+Its public API is:
+- `bool ShouldAllowOrder()` — returns false when circuit is Open
+- `void OnSuccess()` — call after a successful order submission
+- `void OnFailure()` — call after a failed order submission
+- `void RecordOrderRejection(string reason)` — call when NT8 rejects an order
+- `void Reset()` — resets to Closed state
+
+The `ExecutionCircuitBreaker` constructor:
+```csharp
+public ExecutionCircuitBreaker(
+    ILogger<ExecutionCircuitBreaker> logger,
+    int failureThreshold = 3,
+    TimeSpan? timeout = null,
+    TimeSpan? retryTimeout = null,
+    int latencyWindowSize = 100,
+    int rejectionWindowSize = 10)
+```
+
+**Problem:** It is never instantiated. `NT8StrategyBase` submits orders with no circuit breaker gate.
+
+---
+
+## Exact Changes Required
+
+### 1. Add using statement at top of `NT8StrategyBase.cs`
+
+```csharp
+using NT8.Core.Execution;
+using Microsoft.Extensions.Logging.Abstractions;
+```
+
+### 2. Add private field alongside the other private fields
+
+```csharp
+private ExecutionCircuitBreaker _circuitBreaker;
+```
+
+### 3. Initialize in `InitializeSdkComponents()`, after `_positionSizer = new BasicPositionSizer(_logger);`
+
+```csharp
+_circuitBreaker = new ExecutionCircuitBreaker(
+    NullLogger<ExecutionCircuitBreaker>.Instance,
+    failureThreshold: 3,
+    timeout: TimeSpan.FromSeconds(30));
+```
+
+### 4. Gate `SubmitOrderToNT8()` — add check at top of the method
+
+```csharp
+private void SubmitOrderToNT8(OmsOrderRequest request, StrategyIntent intent)
+{
+    // Circuit breaker gate
+    if (_circuitBreaker != null && !_circuitBreaker.ShouldAllowOrder())
+    {
+        var state = _circuitBreaker.GetState();
+        Print(string.Format("[SDK] Circuit breaker OPEN — order blocked: {0}", state.Reason));
+        if (_logger != null)
+            _logger.LogWarning("Circuit breaker blocked order: {0}", state.Reason);
+        return;
+    }
+
+    try
+    {
+        // ... EXISTING submit logic unchanged ...
+        var orderName = string.Format("SDK_{0}_{1}", intent.Symbol, DateTime.Now.Ticks);
+        _executionAdapter.SubmitOrder(request, orderName);
+
+        if (request.Side == OmsOrderSide.Buy)
+        { ... existing EnterLong/EnterLongLimit/etc ... }
+        else if (request.Side == OmsOrderSide.Sell)
+        { ... existing EnterShort/etc ... }
+
+        if (intent.StopTicks > 0)
+            SetStopLoss(orderName, CalculationMode.Ticks, (int)intent.StopTicks, false);
+
+        if (intent.TargetTicks.HasValue && intent.TargetTicks.Value > 0)
+            SetProfitTarget(orderName, CalculationMode.Ticks, (int)intent.TargetTicks.Value);
+
+        // Mark success after submission
+        if (_circuitBreaker != null)
+            _circuitBreaker.OnSuccess();
+    }
+    catch (Exception ex)
+    {
+        if (_circuitBreaker != null)
+            _circuitBreaker.OnFailure();
+
+        Print(string.Format("[SDK] SubmitOrderToNT8 failed: {0}", ex.Message));
+        if (_logger != null)
+            _logger.LogError("SubmitOrderToNT8 failed: {0}", ex.Message);
+        throw;
+    }
+}
+```
+
+### 5. Wire rejections in `OnOrderUpdate()`
+
+In the existing `OnOrderUpdate()` override, after the null/name checks, add:
+
+```csharp
+// Record NT8 rejections in circuit breaker
+if (orderState == NinjaTrader.Cbi.OrderState.Rejected && _circuitBreaker != null)
+{
+    var reason = string.Format("{0} {1}", errorCode, nativeError ?? string.Empty);
+    _circuitBreaker.RecordOrderRejection(reason);
+    Print(string.Format("[SDK] Order rejected by NT8: {0}", reason));
+}
+```
+
+---
+
+## Acceptance Criteria
+
+- [ ] `ExecutionCircuitBreaker` is instantiated in `InitializeSdkComponents()`
+- [ ] `SubmitOrderToNT8()` checks `ShouldAllowOrder()` before submitting — if false, prints message and returns
+- [ ] `OnOrderUpdate()` calls `RecordOrderRejection()` when `orderState == OrderState.Rejected`
+- [ ] `OnSuccess()` called after successful order submission
+- [ ] `OnFailure()` called in catch block
+- [ ] `verify-build.bat` passes with zero errors
+- [ ] Existing 240+ tests still pass: `dotnet test NT8-SDK.sln --verbosity minimal`
+

+# TASK-03: Fix TrailingStopManager Placeholder Math
+
+**File:** `src/NT8.Core/Execution/TrailingStopManager.cs`
+**Priority:** HIGH
+**No dependencies**
+**Estimated time:** 1 hour
+
+---
+
+## Background
+
+`CalculateNewStopPrice()` has three broken cases:
+
+**FixedTrailing (broken):**
+```csharp
+return marketPrice - (position.AverageFillPrice - position.AverageFillPrice); // always 0
+```
+
+**ATRTrailing (placeholder):**
+```csharp
+return marketPrice - (position.AverageFillPrice * 0.01m); // uses fill price as ATR proxy
+```
+
+**Chandelier (placeholder):**
+```csharp
+return marketPrice - (position.AverageFillPrice * 0.01m); // same placeholder
+```
+
+The `TrailingStopConfig` class has these fields available — use them:
+- `TrailingAmountTicks` — integer, tick count for fixed trailing distance
+- `AtrMultiplier` — decimal, multiplier for ATR-based methods
+- `Type` — `StopType` enum
+
+Look at `TrailingStopConfig` in the same file or nearby to confirm field names before editing.
+
+---
+
+## Exact Changes Required
+
+Replace the entire `switch` body inside `CalculateNewStopPrice()` with correct math.
+
+**Use tick size = `0.25m` as the default** (ES/NQ standard). The config should ideally carry tick size, but since it currently does not, use `0.25m` as the constant for now with a comment explaining it.
+
+```csharp
+switch (type)
+{
+    case StopType.FixedTrailing:
+    {
+        // Trail by a fixed number of ticks from current market price.
+        // TrailingAmountTicks comes from config; default 8 if zero.
+        var tickSize = 0.25m;
+        var trailingTicks = config.TrailingAmountTicks > 0 ? config.TrailingAmountTicks : 8;
+        var distance = trailingTicks * tickSize;
+
+        return position.Side == OMS.OrderSide.Buy
+            ? marketPrice - distance
+            : marketPrice + distance;
+    }
+
+    case StopType.ATRTrailing:
+    {
+        // Trail by AtrMultiplier * estimated ATR.
+        // We do not have live ATR here, so approximate ATR as (EntryPrice * 0.005)
+        // which is ~0.5% — a conservative proxy for ES/NQ.
+        // TODO: pass actual ATR value via config when available.
+        var atrMultiplier = config.AtrMultiplier > 0 ? config.AtrMultiplier : 2.0m;
+        var estimatedAtr = position.AverageFillPrice * 0.005m;
+        var distance = atrMultiplier * estimatedAtr;
+
+        return position.Side == OMS.OrderSide.Buy
+            ? marketPrice - distance
+            : marketPrice + distance;
+    }
+
+    case StopType.Chandelier:
+    {
+        // Chandelier exit: trail from highest high (approximated as marketPrice)
+        // minus AtrMultiplier * ATR.
+        // Full implementation requires bar history; use same ATR proxy for now.
+        // TODO: pass highest-high and actual ATR via config.
+        var chanMultiplier = config.AtrMultiplier > 0 ? config.AtrMultiplier : 3.0m;
+        var estimatedAtr = position.AverageFillPrice * 0.005m;
+        var distance = chanMultiplier * estimatedAtr;
+
+        return position.Side == OMS.OrderSide.Buy
+            ? marketPrice - distance
+            : marketPrice + distance;
+    }
+
+    case StopType.PercentageTrailing:
+    {
+        // Existing logic is correct — percentage of current price.
+        var pctTrail = 0.02m;
+        return position.Side == OMS.OrderSide.Buy
+            ? marketPrice * (1 - pctTrail)
+            : marketPrice * (1 + pctTrail);
+    }
+
+    default:
+    {
+        // Fixed trailing as fallback
+        var tickSize = 0.25m;
+        var ticks = config.TrailingAmountTicks > 0 ? config.TrailingAmountTicks : 8;
+        return position.Side == OMS.OrderSide.Buy
+            ? marketPrice - (ticks * tickSize)
+            : marketPrice + (ticks * tickSize);
+    }
+}
+```
+
+**IMPORTANT:** The `config` variable is NOT currently a parameter to `CalculateNewStopPrice()`. The current signature is:
+```csharp
+public decimal CalculateNewStopPrice(StopType type, OMS.OrderStatus position, decimal marketPrice)
+```
+
+You need to add `config` as a parameter:
+```csharp
+public decimal CalculateNewStopPrice(StopType type, OMS.OrderStatus position, decimal marketPrice, TrailingStopConfig config)
+```
+
+Then fix the ONE call site inside `UpdateTrailingStop()`:
+```csharp
+var newStopPrice = CalculateNewStopPrice(trailingStop.Config.Type, trailingStop.Position, currentPrice, trailingStop.Config);
+```
+
+---
+
+## Also Create: New Unit Tests
+
+Create `tests/NT8.Core.Tests/Execution/TrailingStopManagerFixedTests.cs`
+
+```csharp
+// Tests that verify FixedTrailing actually moves the stop
+// Test 1: Long position, FixedTrailing 8 ticks → stop = marketPrice - (8 * 0.25) = marketPrice - 2.0
+// Test 2: Short position, FixedTrailing 8 ticks → stop = marketPrice + 2.0
+// Test 3: ATRTrailing multiplier 2 → stop distance > 0
+// Test 4: Stop only updates when favorable (existing UpdateTrailingStop logic test)
+```
+
+---
+
+## Acceptance Criteria
+
+- [ ] `FixedTrailing` for a long position at price 5100 with 8 ticks returns `5100 - 2.0 = 5098.0`
+- [ ] `FixedTrailing` for a short position at price 5100 with 8 ticks returns `5100 + 2.0 = 5102.0`
+- [ ] `ATRTrailing` returns a value meaningfully below market price for longs (not zero, not equal to price)
+- [ ] `Chandelier` returns a value meaningfully below market price for longs (not zero)
+- [ ] `CalculateNewStopPrice` signature updated — call site in `UpdateTrailingStop()` updated
+- [ ] New unit tests pass
+- [ ] All existing tests still pass
+- [ ] `verify-build.bat` passes

+# TASK-04: Add Log Level Filter to BasicLogger
+
+**File:** `src/NT8.Core/Logging/BasicLogger.cs`
+**Priority:** HIGH
+**No dependencies**
+**Estimated time:** 20 min
+
+---
+
+## Background
+
+`BasicLogger` currently writes every log level to console unconditionally. When `EnableVerboseLogging` is false in NT8, you want to suppress `Debug` and `Trace` output.
+
+The current `ILogger` interface (check `src/NT8.Core/Logging/ILogger.cs`) only defines:
+- `LogDebug`, `LogInformation`, `LogWarning`, `LogError`, `LogCritical`
+
+---
+
+## Exact Changes Required
+
+### 1. Add `LogLevel` enum (check if it already exists first — search the project for `LogLevel`)
+
+If it does NOT already exist, add it inside `BasicLogger.cs` or as a separate file in the same folder:
+
+```csharp
+namespace NT8.Core.Logging
+{
+    /// <summary>
+    /// Log severity levels.
+    /// </summary>
+    public enum LogLevel
+    {
+        Debug = 0,
+        Information = 1,
+        Warning = 2,
+        Error = 3,
+        Critical = 4
+    }
+}
+```
+
+### 2. Add `MinimumLevel` property to `BasicLogger`
+
+```csharp
+/// <summary>
+/// Minimum log level to write. Messages below this level are suppressed.
+/// Default is Information.
+/// </summary>
+public LogLevel MinimumLevel { get; set; }
+```
+
+### 3. Update constructor to default to `Information`
+
+```csharp
+public BasicLogger(string categoryName = "")
+{
+    _categoryName = categoryName;
+    MinimumLevel = LogLevel.Information;
+}
+```
+
+### 4. Update `WriteLog()` to skip below minimum
+
+Add a level parameter and check at the start:
+
+```csharp
+private void WriteLog(LogLevel level, string levelLabel, string message, params object[] args)
+{
+    if (level < MinimumLevel)
+        return;
+
+    var timestamp = DateTime.UtcNow.ToString("yyyy-MM-dd HH:mm:ss.fff");
+    var formattedMessage = args.Length > 0 ? String.Format(message, args) : message;
+    var category = !String.IsNullOrEmpty(_categoryName) ? String.Format("[{0}] ", _categoryName) : "";
+    Console.WriteLine(String.Format("{0} [{1}] {2}{3}", timestamp, levelLabel, category, formattedMessage));
+}
+```
+
+### 5. Update each public method to pass its level
+
+```csharp
+public void LogDebug(string message, params object[] args)
+{
+    WriteLog(LogLevel.Debug, "DEBUG", message, args);
+}
+
+public void LogInformation(string message, params object[] args)
+{
+    WriteLog(LogLevel.Information, "INFO", message, args);
+}
+
+public void LogWarning(string message, params object[] args)
+{
+    WriteLog(LogLevel.Warning, "WARN", message, args);
+}
+
+public void LogError(string message, params object[] args)
+{
+    WriteLog(LogLevel.Error, "ERROR", message, args);
+}
+
+public void LogCritical(string message, params object[] args)
+{
+    WriteLog(LogLevel.Critical, "CRITICAL", message, args);
+}
+```
+
+---
+
+## Acceptance Criteria
+
+- [ ] `MinimumLevel = LogLevel.Warning` suppresses `LogDebug` and `LogInformation` calls
+- [ ] `LogWarning`, `LogError`, `LogCritical` still write when `MinimumLevel = LogLevel.Warning`
+- [ ] Default `MinimumLevel` is `Information` (backward compatible)
+- [ ] `verify-build.bat` passes
+- [ ] All existing tests pass (no test should be checking console output for Debug messages)

+# TASK-05: Add CME Holiday Awareness to SessionManager
+
+**File:** `src/NT8.Core/MarketData/SessionManager.cs`
+**Priority:** MEDIUM
+**No dependencies**
+**Estimated time:** 30 min
+
+---
+
+## Background
+
+`IsRegularTradingHours()` currently only checks session time windows. It has no awareness of CME holidays, so the system would attempt to trade on Christmas, Thanksgiving, etc. when markets are closed.
+
+---
+
+## Exact Changes Required
+
+### 1. Add a static holiday set as a private field on `SessionManager`
+
+Add this inside the class (near the other private fields):
+
+```csharp
+// CME US Futures holidays — markets closed all day on these dates.
+// Update annually. Dates are in the format new DateTime(year, month, day).
+private static readonly System.Collections.Generic.HashSet<DateTime> _cmeHolidays =
+    new System.Collections.Generic.HashSet<DateTime>
+    {

+        new DateTime(2025, 1, 20),  // Martin Luther King Jr. Day
+        new DateTime(2025, 2, 17),  // Presidents' Day
+        new DateTime(2025, 4, 18),  // Good Friday
+        new DateTime(2025, 5, 26),  // Memorial Day
+        new DateTime(2025, 6, 19),  // Juneteenth
+        new DateTime(2025, 7, 4),   // Independence Day
+        new DateTime(2025, 9, 1),   // Labor Day
+        new DateTime(2025, 11, 27), // Thanksgiving
+        new DateTime(2025, 12, 25), // Christmas Day
+
+        // 2026 holidays
+        new DateTime(2026, 1, 1),   // New Year's Day
+        new DateTime(2026, 1, 19),  // Martin Luther King Jr. Day
+        new DateTime(2026, 2, 16),  // Presidents' Day
+        new DateTime(2026, 4, 3),   // Good Friday
+        new DateTime(2026, 5, 25),  // Memorial Day
+        new DateTime(2026, 6, 19),  // Juneteenth
+        new DateTime(2026, 7, 4),   // Independence Day (observed Mon 7/3 if falls on Sat — keep both just in case)
+        new DateTime(2026, 9, 7),   // Labor Day
+        new DateTime(2026, 11, 26), // Thanksgiving
+        new DateTime(2026, 12, 25), // Christmas Day
+    };
+```
+
+### 2. Add a helper method
+
+```csharp
+/// <summary>
+/// Returns true if the given UTC date is a CME holiday (market closed all day).
+/// </summary>
+private static bool IsCmeHoliday(DateTime utcTime)
+{
+    // Convert to ET for holiday date comparison
+    try
+    {
+        var estTime = TimeZoneInfo.ConvertTimeFromUtc(utcTime,
+            TimeZoneInfo.FindSystemTimeZoneById("Eastern Standard Time"));
+        return _cmeHolidays.Contains(estTime.Date);
+    }
+    catch (Exception)
+    {
+        return false;
+    }
+}
+```
+
+### 3. Update `IsRegularTradingHours()` to check holidays first
+
+The existing method body is:
+```csharp
+var sessionInfo = GetCurrentSession(symbol, time);
+return sessionInfo.IsRegularHours;
+```
+
+Replace with:
+```csharp
+// Markets are fully closed on CME holidays
+if (IsCmeHoliday(time))
+{
+    _logger.LogInformation("Holiday detected for {0} on {1} — market closed.", symbol, time.Date);
+    return false;
+}
+
+var sessionInfo = GetCurrentSession(symbol, time);
+return sessionInfo.IsRegularHours;
+```
+
+---
+
+## Acceptance Criteria
+
+- [ ] `IsRegularTradingHours("ES", new DateTime(2025, 12, 25, 14, 0, 0, DateTimeKind.Utc))` returns `false`
+- [ ] `IsRegularTradingHours("ES", new DateTime(2025, 12, 26, 14, 0, 0, DateTimeKind.Utc))` returns `true` (normal day)
+- [ ] `IsRegularTradingHours("ES", new DateTime(2025, 11, 27, 14, 0, 0, DateTimeKind.Utc))` returns `false` (Thanksgiving)
+- [ ] `verify-build.bat` passes

+# Task 1 — Wire NT8OrderAdapter.ExecuteInNT8()
+
+**Priority:** CRITICAL  
+**Estimated time:** 3–4 hours  
+**Blocks:** All backtest and live trading  
+**Status:** TODO
+
+---
+
+## Problem
+
+`NT8OrderAdapter.ExecuteInNT8()` in `src/NT8.Adapters/NinjaTrader/NT8OrderAdapter.cs` is a stub.  
+It only logs to an internal list. The actual NT8 calls (`EnterLong`, `EnterShort`, `SetStopLoss`, `SetProfitTarget`) are in a commented-out block and never execute. This is why backtests show zero trades.
+
+---
+
+## What Needs to Change
+
+### File: `src/NT8.Adapters/NinjaTrader/NT8OrderAdapter.cs`
+
+The adapter currently has no reference to the actual NinjaScript `Strategy` object. It needs a way to call NT8 managed order methods. The pattern used by `NT8StrategyBase` is the right model to follow.
+
+**Option A (Recommended):** Inject a callback delegate so the adapter can call NT8 methods without directly holding a NinjaScript reference.
+
+Add a new `INT8ExecutionBridge` interface:
+```csharp
+// new file: src/NT8.Adapters/NinjaTrader/INT8ExecutionBridge.cs
+namespace NT8.Adapters.NinjaTrader
+{
+    /// <summary>
+    /// Provides NT8OrderAdapter access to NinjaScript execution methods.
+    /// Implemented by NT8StrategyBase.
+    /// </summary>
+    public interface INT8ExecutionBridge
+    {
+        /// <summary>Submit a long entry with stop and target.</summary>
+        void EnterLongManaged(int quantity, string signalName, int stopTicks, int targetTicks, double tickSize);
+
+        /// <summary>Submit a short entry with stop and target.</summary>
+        void EnterShortManaged(int quantity, string signalName, int stopTicks, int targetTicks, double tickSize);
+
+        /// <summary>Exit all long positions.</summary>
+        void ExitLongManaged(string signalName);
+
+        /// <summary>Exit all short positions.</summary>
+        void ExitShortManaged(string signalName);
+
+        /// <summary>Flatten the full position immediately.</summary>
+        void FlattenAll();
+    }
+}
+```
+
+Update `NT8OrderAdapter` constructor to accept `INT8ExecutionBridge`:
+```csharp
+public NT8OrderAdapter(INT8ExecutionBridge bridge)
+{
+    if (bridge == null)
+        throw new ArgumentNullException("bridge");
+    _bridge = bridge;
+    _executionHistory = new List<NT8OrderExecutionRecord>();
+}
+```
+
+Implement `ExecuteInNT8()`:
+```csharp
+private void ExecuteInNT8(StrategyIntent intent, SizingResult sizing)
+{
+    if (intent == null)
+        throw new ArgumentNullException("intent");
+    if (sizing == null)
+        throw new ArgumentNullException("sizing");

+# Task 2 — Emergency Kill Switch
+
+**Priority:** CRITICAL  
+**Estimated time:** 1.5–2 hours  
+**Depends on:** Task 1 (INT8ExecutionBridge.FlattenAll must exist)  
+**Status:** TODO
+
+---
+
+## Problem
+
+There is no way to stop a running strategy and flatten positions from the NinjaTrader UI without killing the entire application.  
+`BasicOrderManager.FlattenAll()` exists in the SDK core but nothing surfaces it as a controllable NT8 strategy parameter.
+
+---
+
+## What Needs to Change
+
+### File: `src/NT8.Adapters/Strategies/NT8StrategyBase.cs`
+
+Add two new NinjaScript properties:
+
+```csharp
+// Kill switch — set to true in NT8 UI to flatten everything and stop trading
+[NinjaScriptProperty]
+[Display(Name = "Kill Switch (Flatten & Stop)", GroupName = "Emergency Controls", Order = 1)]
+public bool EnableKillSwitch { get; set; }
+
+// Logging verbosity toggle
+[NinjaScriptProperty]  
+[Display(Name = "Verbose Logging", GroupName = "Debug", Order = 1)]
+public bool EnableVerboseLogging { get; set; }
+```
+
+Set defaults in `OnStateChange` → `State.SetDefaults`:
+```csharp
+EnableKillSwitch = false;
+EnableVerboseLogging = false;
+```
+
+Add kill switch check at the TOP of `OnBarUpdate()`, BEFORE any strategy logic:
+```csharp
+protected override void OnBarUpdate()
+{
+    if (BarsInProgress != 0) return;
+    if (CurrentBar < BarsRequiredToTrade) return;
+
+    // Emergency kill switch — check FIRST, before anything else
+    if (EnableKillSwitch)
+    {
+        if (!_killSwitchTriggered)
+        {
+            _killSwitchTriggered = true;
+            Print(string.Format("[NT8-SDK] KILL SWITCH ACTIVATED at {0}. Flattening all positions.", Time[0]));
+            
+            try
+            {
+                ExitLong("EmergencyFlatten");
+                ExitShort("EmergencyFlatten");
+            }
+            catch (Exception ex)
+            {
+                Print(string.Format("[NT8-SDK] Error during emergency flatten: {0}", ex.Message));
+            }
+        }
+        return;  // Do not process any more bar logic
+    }
+
+    // ... rest of OnBarUpdate
+}
+```
+
+Add the tracking field:
+```csharp
+private bool _killSwitchTriggered = false;
+```
+
+Reset in `OnStateChange` → `State.DataLoaded` or `State.Active`:
+```csharp
+_killSwitchTriggered = false;
+```
+
+---
+
+## Acceptance Criteria
+
+- [ ] `EnableKillSwitch` appears as a checkbox in the NT8 strategy parameter dialog under "Emergency Controls"
+- [ ] Setting `EnableKillSwitch = true` on a running strategy causes `ExitLong` and `ExitShort` to fire on the next bar
+- [ ] Once triggered, no new entries are made (strategy returns early every bar)
+- [ ] A `Print()` message confirms the activation with timestamp
+- [ ] Setting kill switch back to `false` does NOT re-enable trading in the same session (once triggered, stays triggered)
+- [ ] `EnableVerboseLogging` is exposed in parameter dialog under "Debug"
+- [ ] `verify-build.bat` passes
+
+---
+
+## Files to Modify
+
+| File | Action |
+|---|---|
+| `src/NT8.Adapters/Strategies/NT8StrategyBase.cs` | Add `EnableKillSwitch`, `EnableVerboseLogging` params; add kill switch logic to `OnBarUpdate()` |

+# Task 3 — Wire ExecutionCircuitBreaker
+
+**Priority:** HIGH  
+**Estimated time:** 1.5–2 hours  
+**Depends on:** Task 1 (NT8StrategyBase changes)  
+**Status:** TODO
+
+---
+
+## Problem
+
+`ExecutionCircuitBreaker` in `src/NT8.Core/Execution/ExecutionCircuitBreaker.cs` is a complete, well-tested class.  
+It is never instantiated or connected to any live order flow. Orders are submitted regardless of latency or rejection conditions.
+
+---
+
+## What Needs to Change
+
+### File: `src/NT8.Adapters/Strategies/NT8StrategyBase.cs`
+
+**Step 1:** Add `ExecutionCircuitBreaker` as a field on `NT8StrategyBase`.
+
+```csharp
+private ExecutionCircuitBreaker _circuitBreaker;
+```
+
+**Step 2:** Initialize it in `OnStateChange` → `State.DataLoaded`:
+```csharp
+// Use Microsoft.Extensions.Logging NullLogger for now (or wire to BasicLogger)
+_circuitBreaker = new ExecutionCircuitBreaker(
+    new NullLogger<ExecutionCircuitBreaker>(),
+    failureThreshold: 3,
+    timeout: TimeSpan.FromSeconds(30));
+```
+
+**Step 3:** Gate ALL order submissions through the circuit breaker.  
+In the method that calls `ExecuteIntent()` (or wherever orders flow from strategy intent to the adapter), add:
+
+```csharp
+private bool TrySubmitIntent(StrategyIntent intent, StrategyContext context)
+{
+    if (!_circuitBreaker.ShouldAllowOrder())
+    {
+        var state = _circuitBreaker.GetState();
+        Print(string.Format("[NT8-SDK] Circuit breaker OPEN — order blocked. Reason: {0}", state.Reason));
+        return false;
+    }
+
+    try
+    {
+        _orderAdapter.ExecuteIntent(intent, context, _strategyConfig);
+        _circuitBreaker.OnSuccess();
+        return true;
+    }
+    catch (Exception ex)
+    {
+        _circuitBreaker.OnFailure();
+        _circuitBreaker.RecordOrderRejection(ex.Message);
+        Print(string.Format("[NT8-SDK] Order execution failed: {0}", ex.Message));
+        return false;
+    }
+}
+```
+
+**Step 4:** Wire `OnOrderUpdate` rejections back to the circuit breaker.  
+In `NT8StrategyBase.OnOrderUpdate()`:
+```csharp
+protected override void OnOrderUpdate(Order order, double limitPrice, double stopPrice,
+    int quantity, int filled, double averageFillPrice,
+    OrderState orderState, DateTime time, ErrorCode error, string nativeError)
+{
+    if (orderState == OrderState.Rejected)
+    {
+        if (_circuitBreaker != null)
+        {
+            _circuitBreaker.RecordOrderRejection(
+                string.Format("NT8 rejected order: {0} {1}", error, nativeError));
+        }
+    }
+
+    // Pass through to adapter for state tracking
+    if (_orderAdapter != null)
+    {
+        _orderAdapter.OnOrderUpdate(
+            order != null ? order.Name : "unknown",
+            limitPrice, stopPrice, quantity, filled,
+            averageFillPrice,
+            orderState != null ? orderState.ToString() : "unknown",
+            time, error.ToString(), nativeError ?? string.Empty);
+    }
+}
+```
+
+---
+
+## Acceptance Criteria
+
+- [ ] `ExecutionCircuitBreaker` is instantiated in `NT8StrategyBase`
+- [ ] All order submissions go through `_circuitBreaker.ShouldAllowOrder()` — if false, order is blocked and logged
+- [ ] NT8 order rejections call `_circuitBreaker.RecordOrderRejection()`
+- [ ] 3 consecutive rejections open the circuit breaker (blocks further orders for 30 seconds)
+- [ ] After 30 seconds, circuit breaker enters half-open and allows one test order
+- [ ] `verify-build.bat` passes

+# NT8 SDK Installation Instructions
+
+## Overview
+
+This guide documents manual and scripted deployment of the NT8 SDK into NinjaTrader 8.
+
+## Prerequisites
+
+1. Windows machine with NinjaTrader 8 installed.
+2. NinjaTrader 8 has been launched at least one time so the Custom folder exists.
+3. .NET SDK available for building release binaries.
+4. Repository checked out locally.
+
+## Expected Paths
+
+- Project root: `c:\dev\nt8-sdk`
+- Deployment script: `c:\dev\nt8-sdk\deployment\deploy-to-nt8.bat`
+- NinjaTrader custom folder: `%USERPROFILE%\Documents\NinjaTrader 8\bin\Custom`
+
+## Build Release Artifacts
+
+Run this from repository root:
+
+```bat
+cd c:\dev\nt8-sdk && dotnet build NT8-SDK.sln --configuration Release
+```
+
+Expected outputs:
+
+- `src\NT8.Core\bin\Release\net48\NT8.Core.dll`
+- `src\NT8.Adapters\bin\Release\net48\NT8.Adapters.dll`
+
+## Deploy Using Script (Recommended)
+
+Run:
+
+```bat
+cd c:\dev\nt8-sdk\deployment && deploy-to-nt8.bat
+```
+
+What the script does:
+
+1. Validates NinjaTrader custom folder exists.
+2. Validates release binaries exist.
+3. Creates backup folder under `deployment\backups\<timestamp>`.
+4. Backs up existing deployed SDK files.
+5. Copies DLLs into NinjaTrader Custom folder.
+6. Copies wrapper strategy source files into `Custom\Strategies`.
+7. Verifies expected deployed files exist after copy.
+8. Writes `manifest.txt` into the backup folder with source/destination details.
+
+## Verify Deployment in NinjaTrader 8
+
+1. Open NinjaTrader 8.
+2. Open NinjaScript Editor.
+3. Press `F5` to compile.
+4. Confirm no compile errors.
+5. Open Strategies window and verify wrappers are listed:
+   - `BaseNT8StrategyWrapper`
+   - `SimpleORBNT8Wrapper`
+
+## Rollback Procedure
+
+If deployment must be reverted:
+
+1. Locate the latest backup in `deployment\backups`.
+2. Review `manifest.txt` in that backup folder to confirm file set and paths.
+2. Copy files back into:
+    - `%USERPROFILE%\Documents\NinjaTrader 8\bin\Custom`
+    - `%USERPROFILE%\Documents\NinjaTrader 8\bin\Custom\Strategies`
+3. Recompile in NinjaTrader (`F5`).
+
+## Troubleshooting
+
+### "NinjaTrader Custom folder not found"
+
+- Launch NinjaTrader once.
+- Confirm `%USERPROFILE%\Documents\NinjaTrader 8\bin\Custom` exists.
+
+### "Core DLL not found" or "Adapters DLL not found"
+
+- Re-run release build:
+
+```bat
+cd c:\dev\nt8-sdk && dotnet build NT8-SDK.sln --configuration Release
+```
+
+### NinjaScript compile errors after deploy
+
+- Confirm target framework remains .NET Framework 4.8.
+- Confirm C# 5.0-compatible syntax in wrappers.
+- Restore from backup and redeploy after fixes.
+
+## Operational Notes
+
+- Deploy only when NinjaTrader strategy execution is stopped.
+- Keep timestamped backups for audit and rollback.
+- Keep `manifest.txt` with each backup for deployment traceability.
+- Re-run deployment after every release build update.

+- Regime segmentation and transition analysis implemented in `RegimePerformanceAnalyzer`.
+- Confluence factor validation, weighting recommendations, and score validation implemented in `ConfluenceValidator`.
+
+### Reporting & Export
+
+- Daily/weekly/monthly reporting models and generation in `ReportModels` and `ReportGenerator`.
+- Export support added for text/CSV/JSON.
+- Real-time filter/sort trade ledger behavior implemented in `TradeBlotter`.
+
+### Optimization Tooling
+
+- Parameter sensitivity, grid-search, and walk-forward scaffolding in `ParameterOptimizer`.
+- Monte Carlo simulation, confidence intervals, and risk-of-ruin calculations in `MonteCarloSimulator`.
+- Allocation heuristics and portfolio-level Sharpe estimation in `PortfolioOptimizer`.
+
+---
+
+## Verification
+
+Build and test verification was executed with:
+
+```bat
+.\verify-build.bat
+```
+
+Observed result:
+
+- Build succeeded for all projects.
+- Test suites passed, including analytics additions.
+- Existing warnings (CS1998 in legacy mock/test files) remain unchanged from prior baseline.
+
+---
+
+## Compliance Notes
+
+- Public analytics APIs documented.
+- No interface signatures modified.
+- New implementation isolated to analytics scope and analytics test scope.
+- Thread-safety patterns applied to shared mutable analytics state.
+
+---
+
+## Known Follow-Up Opportunities
+
+- Tighten MAE/MFE calculations with tick-level excursions when full intratrade path data is available.
+- Expand walk-forward optimizer to support richer objective functions and validation windows.
+- Add richer portfolio covariance modeling for larger strategy sets.
+
+---
+
+**Phase 5 is complete and verified.**
