## 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(...) { }
|
||||||
|
}
|
||||||
|
```

## Component Design
|
||||||
|
|
||||||
|
### Strategy Component
|
||||||
|
|
||||||
|
**Purpose:** Generate trading signals based on market data
|
||||||
|
|
||||||
|
**Design Principles:**
|
||||||
|
- Strategies are **pure signal generators**
|
||||||
|
- No direct access to order management or risk
|
||||||
|
- Stateful but isolated
|
||||||
|
- Deterministic for backtesting
|
||||||
|
|
||||||
|
**Interface:**
|
||||||
|
```csharp
|
||||||
|
public interface IStrategy
|
||||||
|
{
|
||||||
|
StrategyIntent? OnBar(BarData bar, StrategyContext context);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Key Characteristics:**
|
||||||
|
- Receives market data and context
|
||||||
|
- Returns trading intent (or null)
|
||||||
|
- No side effects outside internal state
|
||||||
|
- All infrastructure handled by SDK
|
||||||
|
|
||||||
|
**Example Implementation:**
|
||||||
|
```csharp
|
||||||
|
public class SimpleORBStrategy : IStrategy
|
||||||
|
{
|
||||||
|
private double _orbHigh, _orbLow;
|
||||||
|
private bool _orbComplete;
|
||||||
|
|
||||||
|
public StrategyIntent? OnBar(BarData bar, StrategyContext context)
|
||||||
|
{
|
||||||
|
// Update ORB during formation
|
||||||
|
if (!_orbComplete && IsORBPeriod(bar.Time))
|
||||||
|
{
|
||||||
|
UpdateORB(bar);
|
||||||
|
return null;
|
||||||
|
}
|
||||||
|
|
||||||
|
// Generate signal after ORB complete
|
||||||
|
if (_orbComplete && bar.Close > _orbHigh)
|
||||||
|
{
|
||||||
|
return new StrategyIntent(/* long signal */);
|
||||||
|
}
|
||||||
|
|
||||||
|
return null;
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### Risk Management Component
|
||||||
|
|
||||||
|
**Purpose:** Validate all trading decisions against risk parameters
|
||||||
|
|
||||||
|
**Architecture:**
|
||||||
|
|
||||||
|
```
|
||||||
|
BasicRiskManager (Tier 1)
|
||||||
|
├─ Daily loss limits
|
||||||
|
├─ Per-trade risk caps
|
||||||
|
├─ Position count limits
|
||||||
|
└─ Emergency flatten
|
||||||
|
↓ wraps
|
||||||
|
AdvancedRiskManager (Tiers 2-3)
|
||||||
|
├─ Weekly rolling limits (Tier 2)
|
||||||
|
├─ Trailing drawdown (Tier 2)
|
||||||
|
├─ Cross-strategy exposure (Tier 3)
|
||||||
|
├─ Correlation limits (Tier 3)
|
||||||
|
└─ Time-based windows (Tier 3)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Tier Classification:**
|
||||||
|
|
||||||
|
| Tier | Purpose | Scope |
|
||||||
|
|------|---------|-------|
|
||||||
|
| **Tier 1** | Core capital protection | Single account, single day |
|
||||||
|
| **Tier 2** | Extended protection | Multi-day, drawdown |
|
||||||
|
| **Tier 3** | Portfolio management | Cross-strategy, correlation |
|
||||||
|
|
||||||
|
**Validation Flow:**
|
||||||
|
```csharp
|
||||||
|
public RiskDecision ValidateOrder(StrategyIntent intent, StrategyContext context, RiskConfig config)
|
||||||
|
{
|
||||||
|
// 1. Check Tier 1 (via BasicRiskManager)
|
||||||
|
var tier1 = _basicRiskManager.ValidateOrder(intent, context, config);
|
||||||
|
if (!tier1.Allow) return tier1;
|
||||||
|
|
||||||
|
// 2. Check Tier 2
|
||||||
|
if (IsWeeklyLimitBreached()) return Reject("Weekly limit");
|
||||||
|
if (IsDrawdownExceeded()) return Reject("Drawdown limit");
|
||||||
|
|
||||||
|
// 3. Check Tier 3
|
||||||
|
if (IsExposureLimitBreached()) return Reject("Exposure limit");
|
||||||
|
if (IsCorrelationTooHigh()) return Reject("Correlation limit");
|
||||||
|
|
||||||
|
return Allow();
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**State Management:**
|
||||||
|
- Thread-safe with locks
|
||||||
|
- Weekly window: 7-day rolling P&L tracking
|
||||||
|
- Peak equity: Updated on every P&L update
|
||||||
|
- Exposure tracking: Per-symbol aggregation
|
||||||
|
- Correlation matrix: Dynamic updates
|
||||||
|
|
||||||

### Position Sizing Component
|
||||||
|
|
||||||
|
**Purpose:** Calculate optimal contract quantities
|
||||||
|
|
||||||
|
**Architecture:**
|
||||||
|
|
||||||
|
```
|
||||||
|
BasicPositionSizer
|
||||||
|
├─ Fixed Contracts
|
||||||
|
└─ Fixed Dollar Risk
|
||||||
|
↓ extended by
|
||||||
|
AdvancedPositionSizer
|
||||||
|
├─ OptimalFCalculator
|
||||||
|
│ ├─ Historical trade analysis
|
||||||
|
│ ├─ Risk of ruin calculation
|
||||||
|
│ └─ Optimal leverage
|
||||||
|
├─ VolatilityAdjustedSizer
|
||||||
|
│ ├─ ATR-based sizing
|
||||||
|
│ ├─ StdDev-based sizing
|
||||||
|
│ └─ Regime detection
|
||||||
|
└─ Dollar-Risk Override
|
||||||
|
├─ Rounding modes
|
||||||
|
└─ Contract constraints
|
||||||
|
```
|
||||||
|
|
||||||
|
**Sizing Methods:**
|
||||||
|
|
||||||
|
#### Fixed Contracts
|
||||||
|
Simplest method - always trade the same quantity.
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
Contracts = ConfiguredContracts
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Fixed Dollar Risk
|
||||||
|
Target specific dollar risk per trade.
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
Contracts = TargetRisk / (StopTicks × TickValue)
|
||||||
|
```
|
||||||
|
|
||||||
|
#### Optimal-f (Ralph Vince)
|
||||||
|
Maximize geometric growth rate.
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
f* = (Win% × AvgWin - Loss% × AvgLoss) / AvgWin
|
||||||
|
Contracts = (Capital × f*) / RiskPerContract
|
||||||
|
```
|
||||||
|
|
||||||
|
**Considerations:**
|
||||||
|
- Requires historical trade data
|
||||||
|
- Includes risk of ruin check
|
||||||
|
- Conservative approach recommended
|
||||||
|
|
||||||
|
#### Volatility-Adjusted
|
||||||
|
Scale position size based on market volatility.
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
BaseSize = TargetRisk / (ATR × TickValue)
|
||||||
|
AdjustedSize = BaseSize × (NormalATR / CurrentATR)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Volatility Regimes:**
|
||||||
|
- **Low:** CurrentATR < 0.8 × NormalATR → Increase size
|
||||||
|
- **Normal:** 0.8 ≤ ratio ≤ 1.2 → Standard size
|
||||||
|
- **High:** CurrentATR > 1.2 × NormalATR → Reduce size
|
||||||
|
|
||||||

### Order Management Component
|
||||||
|
|
||||||
|
**Purpose:** Manage complete order lifecycle
|
||||||
|
|
||||||
|
**State Machine:**
|
||||||

│ Rejected │ ← NT8 Rejects at any point
|
||||||
|
└──────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
**State Transitions:**
|
||||||
|
|
||||||
|
| From | To | Trigger | Validation |
|
||||||
|
|------|----|---------|-----------|
|
||||||
|
| `Pending` | `Working` | NT8 accepts | Auto |
|
||||||
|
| `Pending` | `Rejected` | NT8 rejects | Auto |
|
||||||
|
| `Working` | `PartiallyFilled` | First partial fill | FilledQty < TotalQty |
|
||||||
|
| `Working` | `Filled` | Complete fill | FilledQty == TotalQty |
|
||||||
|
| `Working` | `Cancelled` | Cancel request | Must be working |
|
||||||
|
| `PartiallyFilled` | `Filled` | Final fill | FilledQty == TotalQty |
|
||||||
|
| `PartiallyFilled` | `Cancelled` | Cancel remainder | Allowed |
|
||||||
|
|
||||||
|
**Thread Safety:**
|
||||||
|
```csharp
|
||||||
|
private readonly Dictionary<string, OrderStatus> _orders;
|
||||||
|
private readonly object _lock = new object();
|
||||||
|
|
||||||
|
public OrderStatus? GetOrderStatus(string orderId)
|
||||||
|
{
|
||||||
|
lock (_lock)
|
||||||
|
{
|
||||||
|
return _orders.TryGetValue(orderId, out var status) ? status : null;
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Event Notifications:**
|
||||||
|
```csharp
|
||||||
|
private readonly List<Action<OrderStatus>> _callbacks;
|
||||||
|
|
||||||
|
public void SubscribeToOrderUpdates(Action<OrderStatus> callback)
|
||||||
|
{
|
||||||
|
lock (_lock)
|
||||||
|
{
|
||||||
|
_callbacks.Add(callback);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
private void NotifyOrderUpdate(OrderStatus status)
|
||||||
|
{
|
||||||
|
List<Action<OrderStatus>> callbacks;
|
||||||
|
lock (_lock)
|
||||||
|
{
|
||||||
|
callbacks = new List<Action<OrderStatus>>(_callbacks);
|
||||||
|
}
|
||||||
|
|
||||||
|
// Raise events outside lock
|
||||||
|
foreach (var callback in callbacks)
|
||||||
|
{
|
||||||
|
try { callback(status); }
|
||||||
|
catch { /* Log and continue */ }
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||

### NT8 Adapter Component
|
||||||
|
|
||||||
|
**Purpose:** Bridge SDK and NinjaTrader 8 platform
|
||||||
|
|
||||||
|
**Responsibilities:**
|
||||||
|
1. **Data Conversion** - NT8 ↔ SDK format conversion
|
||||||
|
2. **Order Submission** - SDK requests → NT8 orders
|
||||||
|
3. **Event Handling** - NT8 callbacks → SDK notifications
|
||||||
|
4. **Error Translation** - NT8 errors → SDK exceptions
|
||||||
|
|
||||||
|
**Data Conversion Example:**
|
||||||
|
```csharp
|
||||||
|
public class NT8DataConverter
|
||||||
|
{
|
||||||
|
public static BarData ConvertBar(/* NT8 bar parameters */)
|
||||||
|
{
|
||||||
|
return new BarData(
|
||||||
|
symbol: Instrument.MasterInstrument.Name,
|
||||||
|
time: Time[0],
|
||||||
|
open: Open[0],
|
||||||
|
high: High[0],
|
||||||
|
low: Low[0],
|
||||||
|
close: Close[0],
|
||||||
|
volume: Volume[0],
|
||||||
|
barSize: TimeSpan.FromMinutes(BarsPeriod.Value)
|
||||||
|
);
|
||||||
|
}
|
||||||
|
|
||||||
|
public static Position ConvertPosition(/* NT8 position */)
|
||||||
|
{
|
||||||
|
return new Position(
|
||||||
|
symbol: Instrument.MasterInstrument.Name,
|
||||||
|
quantity: Position.Quantity,
|
||||||
|
averagePrice: Position.AveragePrice,
|
||||||
|
unrealizedPnL: Position.GetUnrealizedProfitLoss(PerformanceUnit.Currency),
|
||||||
|
realizedPnL: SystemPerformance.AllTrades.TradesPerformance.Currency.CumProfit,
|
||||||
|
lastUpdate: DateTime.UtcNow
|
||||||
|
);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Order Submission Flow:**
|
||||||
|
```
|
||||||
|
SDK OrderRequest
|
||||||
|
↓ convert
|
||||||
|
NT8 Order Parameters
|
||||||
|
↓ submit
|
||||||
|
NT8 EnterLong() / EnterShort()
|
||||||
|
↓ callback
|
||||||
|
NT8 OnOrderUpdate()
|
||||||
|
↓ convert
|
||||||
|
SDK OrderStatus
|
||||||
|
↓ notify
|
||||||
|
Strategy Callbacks
|
||||||
|
```
|
||||||
|
|
||||||
|

## Threading Model
|
||||||
|
|
||||||
|
### Thread Safety Strategy
|
||||||
|
|
||||||
|
**Principle:** All shared state protected by locks
|
||||||
|
|
||||||
|
**Shared State Identification:**
|
||||||
|
- Dictionaries (orders, positions, P&L tracking)
|
||||||
|
- Lists (callbacks, history)
|
||||||
|
- Mutable fields (counters, accumulators)
|
||||||
|
|
||||||
|
**Lock Pattern:**
|
||||||
|
```csharp
|
||||||
|
private readonly object _lock = new object();
|
||||||
|
|
||||||
|
// Read operation
|
||||||
|
public TValue GetValue(TKey key)
|
||||||
|
{
|
||||||
|
lock (_lock)
|
||||||
|
{
|
||||||
|
return _dictionary.TryGetValue(key, out var value) ? value : default;
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
// Write operation
|
||||||
|
public void SetValue(TKey key, TValue value)
|
||||||
|
{
|
||||||
|
lock (_lock)
|
||||||
|
{
|
||||||
|
_dictionary[key] = value;
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
// Complex operation
|
||||||
|
public void ComplexOperation()
|
||||||
|
{
|
||||||
|
lock (_lock)
|
||||||
|
{
|
||||||
|
// Multiple operations under single lock
|
||||||
|
var value = _dictionary[key];
|
||||||
|
value = Transform(value);
|
||||||
|
_dictionary[key] = value;
|
||||||
|
_counter++;
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Event Notification Pattern:**
|
||||||
|
```csharp
|
||||||
|
public void NotifySubscribers(TEventData data)
|
||||||
|
{
|
||||||
|
List<Action<TEventData>> callbacks;
|
||||||
|
|
||||||
|
// Copy callbacks under lock
|
||||||
|
lock (_lock)
|
||||||
|
{
|
||||||
|
callbacks = new List<Action<TEventData>>(_callbacks);
|
||||||
|
}
|
||||||
|
|
||||||
|
// Raise events outside lock to prevent deadlocks
|
||||||
|
foreach (var callback in callbacks)
|
||||||
|
{
|
||||||
|
try
|
||||||
|
{
|
||||||
|
callback(data);
|
||||||
|
}
|
||||||
|
catch (Exception ex)
|
||||||
|
{
|
||||||
|
_logger.LogError("Callback error: {0}", ex.Message);
|
||||||
|
// Continue with other callbacks
|
||||||
|
}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Threading Scenarios
|
||||||
|
|
||||||
|
**Scenario 1: Concurrent Strategy Execution**
|
||||||
|
- Multiple strategies call risk/sizing simultaneously
|
||||||
|
- Each component has own lock
|
||||||
|
- No shared state between strategies
|
||||||
|
- Result: Safe concurrent execution
|
||||||
|
|
||||||
|
**Scenario 2: Order Updates During Validation**
|
||||||
|
- Strategy validates order (holds risk lock)
|
||||||
|
- NT8 callback updates P&L (needs risk lock)
|
||||||
|
- Result: Callback waits for validation to complete
|
||||||
|
- Performance: <1ms typical lock contention
|
||||||
|
|
||||||
|
**Scenario 3: Emergency Flatten During Trading**
|
||||||
|
- Multiple strategies active
|
||||||
|
- EmergencyFlatten() called
|
||||||
|
- Result: All new orders rejected, existing orders cancelled
|
||||||
|
- Thread-safe state transition
|
||||||
|
|
||||||

|
|
||||||
|
## State Management
|
||||||
|
|
||||||
|
### Risk Manager State
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
private class RiskState
|
||||||
|
{
|
||||||
|
// Tier 1
|
||||||
|
public double DailyPnL { get; set; }
|
||||||
|
public bool TradingHalted { get; set; }
|
||||||
|
|
||||||
|
// Tier 2
|
||||||
|
public Queue<DailyPnL> WeeklyWindow { get; set; } // 7 days
|
||||||
|
public double PeakEquity { get; set; }
|
||||||
|
public double CurrentEquity { get; set; }
|
||||||
|
|
||||||
|
// Tier 3
|
||||||
|
public Dictionary<string, double> SymbolExposure { get; set; }
|
||||||
|
public CorrelationMatrix Correlations { get; set; }
|
||||||
|
|
||||||
|
// All protected by _lock
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**State Updates:**
|
||||||
|
- **Daily Reset:** Midnight UTC, clear daily P&L
|
||||||
|
- **Weekly Rollover:** Monday, drop oldest day
|
||||||
|
- **Peak Update:** On every positive P&L update
|
||||||
|
- **Exposure Update:** On every fill
|
||||||
|
|
||||||
|
### Order Manager State
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
private class OrderManagerState
|
||||||
|
{
|
||||||
|
public Dictionary<string, OrderStatus> Orders { get; set; }
|
||||||
|
public Dictionary<string, List<OrderFill>> Fills { get; set; }
|
||||||
|
public Dictionary<string, Position> Positions { get; set; }
|
||||||
|
|
||||||
|
// State history for auditability
|
||||||
|
public List<StateTransition> TransitionHistory { get; set; }
|
||||||
|
|
||||||
|
// All protected by _lock
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**State Persistence:**
|
||||||
|
- In-memory only (current implementation)
|
||||||
|
- Future: Optional database persistence
|
||||||
|
- Replay: State reconstructable from event log
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Error Handling
|
||||||
|
|
||||||
|
### Error Categories
|
||||||
|
|
||||||
|
**Level 1: Validation Errors**
|
||||||
|
- Expected during normal operation
|
||||||
|
- Example: Risk limit exceeded
|
||||||
|
- Handling: Return error result, log at Info/Warning
|
||||||
|
|
||||||
|
**Level 2: Operational Errors**
|
||||||
|
- Recoverable issues
|
||||||
|
- Example: Network timeout, order rejection
|
||||||
|
- Handling: Log error, retry if appropriate, notify user
|
||||||
|
|
||||||
|
**Level 3: System Errors**
|
||||||
|
- Unexpected critical issues
|
||||||
|
- Example: Null reference, state corruption
|
||||||
|
- Handling: Log critical, emergency flatten, halt trading
|
||||||
|
|
||||||
|
### Error Handling Pattern
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
public ReturnType PublicMethod(Type parameter)
|
||||||
|
{
|
||||||
|
// 1. Parameter validation
|
||||||
|
if (parameter == null)
|
||||||
|
throw new ArgumentNullException(nameof(parameter));
|
||||||
|
|
||||||
|
if (!IsValid(parameter))
|
||||||
|
throw new ArgumentException("Invalid parameter", nameof(parameter));
|
||||||
|
|
||||||
|
try
|
||||||
|
{
|
||||||
|
// 2. Main logic
|
||||||
|
return Implementation(parameter);
|
||||||
|
}
|
||||||
|
catch (ExpectedException ex)
|
||||||
|
{
|
||||||
|
// 3. Expected errors
|
||||||
|
_logger.LogWarning("Expected error: {0}", ex.Message);
|
||||||
|
return DefaultValue;
|
||||||
|
}
|
||||||
|
catch (Exception ex)
|
||||||
|
{
|
||||||
|
// 4. Unexpected errors
|
||||||
|
_logger.LogError("Unexpected error in {0}: {1}", nameof(PublicMethod), ex.Message);
|
||||||
|
throw; // Re-throw for caller to handle
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Circuit Breaker Pattern
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
private int _consecutiveErrors = 0;
|
||||||
|
private const int MaxConsecutiveErrors = 5;
|
||||||
|
|
||||||
|
public RiskDecision ValidateOrder(StrategyIntent intent, StrategyContext context, RiskConfig config)
|
||||||
|
{
|
||||||
|
try
|
||||||
|
{
|
||||||
|
var result = ValidateOrderInternal(intent, context, config);
|
||||||
|
_consecutiveErrors = 0; // Reset on success
|
||||||
|
return result;
|
||||||
|
}
|
||||||
|
catch (Exception ex)
|
||||||
|
{
|
||||||
|
_consecutiveErrors++;
|
||||||
|
|
||||||
|
if (_consecutiveErrors >= MaxConsecutiveErrors)
|
||||||
|
{
|
||||||
|
_logger.LogCritical("Circuit breaker triggered: {0} consecutive errors", _consecutiveErrors);
|
||||||
|
_ = EmergencyFlatten("Circuit breaker");
|
||||||
|
}
|
||||||
|
|
||||||
|
throw;
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Performance Considerations
|
||||||
|
|
||||||
|
### Latency Targets
|
||||||
|
|
||||||
|
| Component | Target | Achieved | Criticality |
|
||||||
|
|-----------|--------|----------|-------------|
|
||||||
|
| Risk Validation | <5ms | <3ms | High |
|
||||||
|
| Position Sizing | <3ms | <2ms | Medium |
|
||||||
|
| Order Submission | <10ms | <8ms | High |
|
||||||
|
| State Update | <1ms | <0.5ms | Medium |
|
||||||
|
| **Total Tick-to-Trade** | **<200ms** | **<150ms** | **Critical** |
|
||||||
|
|
||||||
|
### Optimization Techniques
|
||||||
|
|
||||||
|
**1. Lock Granularity**
|
||||||
|
```csharp
|
||||||
|
// Bad: Single lock for everything
|
||||||
|
private readonly object _globalLock = new object();
|
||||||
|
|
||||||
|
// Good: Separate locks for independent state
|
||||||
|
private readonly object _ordersLock = new object();
|
||||||
|
private readonly object _positionsLock = new object();
|
||||||
|
private readonly object _pnlLock = new object();
|
||||||
|
```
|
||||||
|
|
||||||
|
**2. Copy-on-Read for Collections**
|
||||||
|
```csharp
|
||||||
|
// Minimize lock duration
|
||||||
|
public List<OrderStatus> GetActiveOrders()
|
||||||
|
{
|
||||||
|
lock (_lock)
|
||||||
|
{
|
||||||
|
return _orders.Values
|
||||||
|
.Where(o => IsActive(o.State))
|
||||||
|
.ToList(); // Copy under lock
|
||||||
|
}
|
||||||
|
// Processing happens outside lock
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**3. Lazy Initialization**
|
||||||
|
```csharp
|
||||||
|
private OptimalFCalculator _calculator;
|
||||||
|
private readonly object _calculatorLock = new object();
|
||||||
|
|
||||||
|
private OptimalFCalculator GetCalculator()
|
||||||
|
{
|
||||||
|
if (_calculator == null)
|
||||||
|
{
|
||||||
|
lock (_calculatorLock)
|
||||||
|
{
|
||||||
|
if (_calculator == null) // Double-check
|
||||||
|
{
|
||||||
|
_calculator = new OptimalFCalculator(_logger);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
return _calculator;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**4. String Formatting**
|
||||||
|
```csharp
|
||||||
|
// C# 5.0 compliant, minimal allocations
|
||||||
|
_logger.LogDebug("Order {0}: {1} {2} @ {3:F2}",
|
||||||
|
orderId, side, quantity, price);
|
||||||
|
```
|
||||||
|
|
||||||
|
**5. Avoid LINQ in Hot Paths**
|
||||||
|
```csharp
|
||||||
|
// Bad: LINQ in critical path
|
||||||
|
var activeOrders = _orders.Values.Where(o => o.State == OrderState.Working).Count();
|
||||||
|
|
||||||
|
// Good: Direct iteration
|
||||||
|
int activeCount = 0;
|
||||||
|
foreach (var order in _orders.Values)
|
||||||
|
{
|
||||||
|
if (order.State == OrderState.Working)
|
||||||
|
activeCount++;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Memory Management
|
||||||
|
|
||||||
|
**Avoid Allocations in Hot Paths:**
|
||||||
|
```csharp
|
||||||
|
// Reuse dictionaries for metadata
|
||||||
|
private readonly Dictionary<string, object> _reuseableMetadata = new Dictionary<string, object>();
|
||||||
|
|
||||||
|
public RiskDecision ValidateOrder(...)
|
||||||
|
{
|
||||||
|
lock (_lock)
|
||||||
|
{
|
||||||
|
_reuseableMetadata.Clear();
|
||||||
|
_reuseableMetadata["daily_pnl"] = _dailyPnL;
|
||||||
|
_reuseableMetadata["limit"] = config.DailyLossLimit;
|
||||||
|
|
||||||
|
return new RiskDecision(allow, reason, null, level, _reuseableMetadata);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Object Pooling for Events:**
|
||||||
|
```csharp
|
||||||
|
// Future optimization: Pool frequently-created objects
|
||||||
|
private readonly ObjectPool<OrderStatus> _statusPool;
|
||||||
|
|
||||||
|
public OrderStatus CreateOrderStatus(...)
|
||||||
|
{
|
||||||
|
var status = _statusPool.Get();
|
||||||
|
status.OrderId = orderId;
|
||||||
|
// ... populate
|
||||||
|
return status;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|

### Thread Safety Implementation
|
||||||
|
|
||||||
|
All components use proper locking:
|
||||||
|
|
||||||
|
```csharp
|
||||||
|
private readonly object _lock = new object();
|
||||||
|
|
||||||
|
public void ThreadSafeMethod()
|
||||||
|
{
|
||||||
|
lock (_lock)
|
||||||
|
{
|
||||||
|
// All shared state access protected
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Verified Patterns:**
|
||||||
|
- ✅ Dictionary access protected
|
||||||
|
- ✅ List modifications protected
|
||||||
|
- ✅ State updates atomic
|
||||||
|
- ✅ Events raised outside locks
|
||||||
|
|
||||||
|
### C# 5.0 Compliance
|
||||||
|
|
||||||
|
**Verified Restrictions:**
|
||||||
|
- ✅ No string interpolation (`$"..."`)
|
||||||
|
- ✅ No null-conditional operators (`?.`)
|
||||||
|
- ✅ No expression-bodied members (`=>`)
|
||||||
|
- ✅ No inline out variables
|
||||||
|
- ✅ All code uses `string.Format()`
|
||||||
|

|
||||||
|
↓ Generates StrategyIntent
|
||||||
|
Risk Layer (IRiskManager)

|
├─ BasicRiskManager (Tier 1)
|
||||||
|
└─ AdvancedRiskManager (Tiers 2-3)

|
### Design Principles
|
||||||
|
|
||||||
|
1. **Risk-First** - No trade bypasses risk validation
|
||||||
|
2. **Separation of Concerns** - Clear boundaries between layers
|
||||||
|
3. **Immutability** - Record types for data models
|
||||||
|
4. **Thread Safety** - Lock-based synchronization on all shared state
|
||||||
|
5. **Determinism** - Reproducible for backtesting and auditing

## 🔧 Components
|
||||||
|
|
||||||
|
### Core Components
|
||||||
|
|
||||||
|
#### 1. Strategy Interface (`IStrategy`)
|
||||||
|
|
||||||
|
Strategies implement signal generation only. All infrastructure handled by SDK.
|
||||||
|
|
||||||
|
**Key Methods:**
|
||||||
|
- `OnBar(BarData, StrategyContext)` - Process new bar data
|
||||||
|
- `OnTick(TickData, StrategyContext)` - Process tick data (optional)
|
||||||
|
- `GetParameters()` / `SetParameters()` - Configuration management
|
||||||
|
|
||||||
|
**Example:** `SimpleORBStrategy` - Opening Range Breakout implementation
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
#### 2. Risk Management (`IRiskManager`)
|
||||||
|
|
||||||
|
Multi-tier risk control system protecting capital.
|
||||||
|
|
||||||
|
**BasicRiskManager (Tier 1):**
|
||||||
|
- Daily loss limits with auto-halt
|
||||||
|
- Per-trade risk caps
|
||||||
|
- Position count limits
|
||||||
|
- Emergency flatten capability
|
||||||
|
|
||||||
|
**AdvancedRiskManager (Tiers 2-3):**
|
||||||
|
- Weekly rolling loss limits (7-day window)
|
||||||
|
- Trailing drawdown protection from peak equity
|
||||||
|
- Cross-strategy exposure limits by symbol
|
||||||
|
- Correlation-based position limits
|
||||||
|
- Time-based trading windows
|
||||||
|
- Risk mode system (Normal/Aggressive/Conservative)
|
||||||
|
- Cooldown periods after violations
|
||||||
|
|
||||||
|
**Key Features:**
|
||||||
|
- Automatic Monday weekly rollover
|
||||||
|
- 80% warning thresholds
|
||||||
|
- Dynamic configuration updates
|
||||||
|
- Comprehensive logging at all levels
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
#### 3. Position Sizing (`IPositionSizer`)
|
||||||
|
|
||||||
|
Intelligent contract quantity determination.
|
||||||
|
|
||||||
|
**BasicPositionSizer:**
|
||||||
|
- Fixed contracts
|
||||||
|
- Fixed dollar risk
|
||||||
|
|
||||||
|
**AdvancedPositionSizer:**
|
||||||
|
- **Optimal-f (Ralph Vince method)**
|
||||||
|
- Historical trade analysis
|
||||||
|
- Risk of ruin calculation
|
||||||
|
- Optimal leverage determination
|
||||||
|
- **Volatility-Adjusted Sizing**
|
||||||
|
- ATR-based sizing
|
||||||
|
- Standard deviation sizing
|
||||||
|
- Volatility regime detection
|
||||||
|
- Dynamic adjustment based on market conditions
|
||||||
|
- **Dollar-Risk Override**
|
||||||
|
- Precise risk targeting
|
||||||
|
- Rounding modes (Floor/Ceiling/Nearest)
|
||||||
|
- Contract constraints (min/max/lot size)
|
||||||
|
|
||||||
|
**Formula Examples:**
|
||||||
|
|
||||||
|
```
|
||||||
|
Optimal-f:
|
||||||
|
f* = (Win% × AvgWin - Loss% × AvgLoss) / AvgWin
|
||||||
|
Contracts = (Capital × f*) / RiskPerContract
|
||||||
|
|
||||||
|
Volatility-Adjusted:
|
||||||
|
BaseSize = TargetRisk / (ATR × TickValue)
|
||||||
|
AdjustedSize = BaseSize × (NormalVol / CurrentVol)
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
#### 4. Order Management (`IOrderManager`)
|
||||||
|
|
||||||
|
Complete order lifecycle management with formal state machine.
|
||||||
|
|
||||||
|
**State Machine:**
|
||||||
|
```
|
||||||
|
Pending → Working → PartiallyFilled → Filled
|
||||||
|
↓ ↓
|
||||||
|
Cancelled Cancelled
|
||||||
|
↓
|
||||||
|
Rejected
|
||||||
|
```
|
||||||
|
|
||||||
|
**Features:**
|
||||||
|
- Thread-safe order tracking
|
||||||
|
- State transition validation
|
||||||
|
- Partial fill aggregation
|
||||||
|
- Order retry logic
|
||||||
|
- Position reconciliation
|
||||||
|
- Emergency flatten with fallback
|
||||||
|
|
||||||
|
**Key Methods:**
|
||||||
|
- `SubmitOrderAsync()` - Submit new order
|
||||||
|
- `ModifyOrderAsync()` - Modify working order
|
||||||
|
- `CancelOrderAsync()` - Cancel order
|
||||||
|
- `FlattenPosition()` - Emergency position close
|
||||||
|
- `GetOrderStatus()` / `GetActiveOrders()` - Order queries
|
||||||
|
- `SubscribeToOrderUpdates()` - Real-time notifications

||||||
|
```
|
||||||
|
|
||||||
|
**Step 4: Compile in NT8**
|
||||||
|
1. Open NinjaTrader 8
|
||||||
|
2. Tools → NinjaScript Editor
|
||||||

|
||||||
|
4. Verify no errors
|
||||||
|
|
||||||
|
**Step 5: Test on Simulation**
|
||||||
|
1. Create new strategy instance
|
||||||
|
2. Set parameters
|
||||||
|
3. Enable on simulation account
|
||||||
|
4. Monitor for 1+ hours
|
||||||
|
5. Verify risk controls trigger correctly
|
||||||
|
|
||||||
|
**Step 6: Deploy to Live** (only after simulation success)
|
||||||
|
1. Create new strategy instance
|
||||||
|
2. Use conservative parameters
|
||||||
|

|
||||||
|
### Coding Standards
|
||||||
|
|
||||||
|
**Language Requirements:**
|
||||||
|
- C# 5.0 syntax only (no C# 6+ features)
|
||||||
|
- .NET Framework 4.8 target
|
||||||
|
- No `$"string interpolation"` (use `string.Format()`)
|
||||||
|
- No `?.` null-conditional (use explicit checks)
|
||||||
|
- No `=>` expression bodies (use full method syntax)
|
||||||
|
|
||||||
|
**Thread Safety:**
|
||||||
|
```csharp
|
||||||
|
private readonly object _lock = new object();
|
||||||
|
|
||||||
|
public void ThreadSafeMethod()
|
||||||
|
{
|
||||||
|
lock (_lock)
|
||||||
|
{
|
||||||
|
// Access shared state here
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Error Handling:**
|
||||||
|
```csharp
|
||||||
|
public ReturnType PublicMethod(Type parameter)
|
||||||
|
{
|
||||||
|
if (parameter == null)
|
||||||
|
throw new ArgumentNullException("parameter");
|
||||||
|
|
||||||
|
try
|
||||||
|
{
|
||||||
|
// Implementation
|
||||||
|
}
|
||||||
|
catch (SpecificException ex)
|
||||||
|
{
|
||||||
|
_logger.LogError("Error in method: {0}", ex.Message);
|
||||||
|
throw;
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Documentation:**
|
||||||
|
```csharp
|
||||||
|
/// <summary>
|
||||||
|
/// Brief description of what this does
|
||||||
|
/// </summary>
|
||||||
|
/// <param name="parameter">Parameter description</param>
|
||||||
|
/// <returns>Return value description</returns>
|
||||||

public ReturnType Method(Type parameter)
|
||||||
|
{
|
||||||
|
// Implementation
|
||||||
|
}
|

## 🔒 Security & Risk
|
||||||
|
|
||||||
|
### Risk Controls
|
||||||
|
|
||||||
|
**Tier 1 (Always Active):**
|
||||||
|
- Daily loss limits with automatic halt
|
||||||
|
- Per-trade risk caps
|
||||||
|
- Position count limits
|
||||||
|
|
||||||
|
**Tier 2 (Recommended):**
|
||||||
|
- Weekly rolling loss limits
|
||||||
|
- Trailing drawdown protection
|
||||||
|
|
||||||
|
**Tier 3 (Advanced):**
|
||||||
|
- Cross-strategy exposure limits
|
||||||
|
- Correlation-based position limits
|
||||||
|
- Time-based trading windows
|
||||||
|
|
||||||
|
### Emergency Procedures
|
||||||
|
|
||||||
|
**Manual Override:**
|
||||||
|
```csharp
|
||||||
|
await riskManager.EmergencyFlatten("Manual intervention");
|
||||||
|
```
|
||||||
|
|
||||||
|
**Automatic Triggers:**
|
||||||
|
- Daily loss limit breach
|
||||||
|
- Weekly loss limit breach
|
||||||
|
- Drawdown threshold exceeded
|
||||||
|
- Connection loss detection
