public class MyFirstStrategy : IStrategy
|
||||
{
|
||||
public StrategyIntent? OnBar(BarData bar, StrategyContext context)
|
||||
{
|
||||
// Simple strategy: Buy on breakout
|
||||
if (bar.Close > bar.Open && context.CurrentPosition.Quantity == 0)
|
||||
{
|
||||
return new StrategyIntent(
|

## 🏗️ Architecture
|
||||
|
||||
### Component Flow
|
||||
|
||||
```
|
||||
Strategy Layer (IStrategy)
|
||||
↓ Generates StrategyIntent
|
||||
Risk Layer (IRiskManager)
|
||||
├─ BasicRiskManager (Tier 1)
|
||||
└─ AdvancedRiskManager (Tiers 2-3)
|
||||
↓ Validates → RiskDecision
|
||||
Sizing Layer (IPositionSizer)
|
||||
├─ BasicPositionSizer
|
||||
└─ AdvancedPositionSizer (Optimal-f, Volatility)
|
||||
↓ Calculates → SizingResult
|
||||
OMS Layer (IOrderManager)
|
||||
└─ BasicOrderManager (State Machine)
|
||||
↓ Manages → OrderStatus
|
||||
NT8 Adapter Layer (INT8OrderAdapter)
|
||||
↓ Bridges to NinjaTrader 8
|
||||
NinjaTrader 8 Platform
|
||||
```
|
||||
|
||||
### 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

using FluentAssertions;
|
||||
|
||||
public class MyStrategyTests
|
||||
{
|
||||
[Fact]
|
||||
public void OnBar_WithBreakout_ShouldGenerateIntent()
|
||||
{
|
||||
// Arrange
|
||||
var strategy = new MyStrategy(logger);
|
||||
var bar = new BarData("ES", DateTime.Now, 4200, 4210, 4195, 4208, 1000, TimeSpan.FromMinutes(5));
|
||||
var context = CreateTestContext();
|
||||
|
||||
// Act
|
||||
var intent = strategy.OnBar(bar, context);
|
||||
|
||||
// Assert
|
||||
intent.Should().NotBeNull();
|
||||
intent.Side.Should().Be(OrderSide.Buy);
|
||||
intent.Symbol.Should().Be("ES");
|
||||
}
|
||||
}
|
||||
```
|

**Step 2: Copy DLLs to NT8**
|
||||
```
|
||||
Source: src/NT8.Core/bin/Release/net48/
|
||||
Destination: C:\Users\[Username]\Documents\NinjaTrader 8\bin\Custom\
|
||||
```
|
||||
|
||||
**Step 3: Deploy Strategy Wrappers**
|
||||
```
|
||||
Source: src/NT8.Adapters/Wrappers/*.cs
|
||||
Destination: C:\Users\[Username]\Documents\NinjaTrader 8\bin\Custom\Strategies\
|
||||
```
|
||||
|
||||
**Step 4: Compile in NT8**
|
||||
1. Open NinjaTrader 8
|
||||
2. Tools → NinjaScript Editor
|
||||
3. Compile → Compile All
|
||||
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
|
||||
3. Start with minimum position sizes
|
||||
4. Monitor continuously

```
|
||||
|
||||
### 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
|
||||
}
|
||||
```
|
||||
|
||||
