Framework 4.8 compatibility and follow established patterns when working on the NT8 SDK project. + +## Required Reading +AI agents MUST review these documents before making any changes: +1. `AI_DEVELOPMENT_GUIDELINES.md` - Core compatibility requirements +2. `CODE_STYLE_GUIDE.md` - Required code patterns +3. `CODE_REVIEW_CHECKLIST.md` - Pre-commit verification +4. `NET_FRAMEWORK_CONVERSION.md` - Background on compatibility changes + +## Project Constraints + +### Hard Requirements (Non-Negotiable) +- **Framework**: .NET Framework 4.8 ONLY +- **Language**: C# 5.0 features ONLY +- **Architecture**: Risk-first design pattern +- **Testing**: MSTest framework ONLY +- **Build**: Must pass `.\verify-build.bat` with zero errors + +### Forbidden Technologies +- .NET Core/.NET 5+/.NET 6+/.NET 9+ +- C# 6+ language features (records, nullable refs, string interpolation) +- Microsoft.Extensions.* packages +- xUnit, NUnit (use MSTest only) +- Modern async patterns (use traditional async/await) + +## Development Workflow + +### Before Starting Any Task +1. Run `.\verify-build.bat` to confirm baseline +2. Review existing code patterns in the module you're working on +3. Check `AI_DEVELOPMENT_GUIDELINES.md` for specific requirements + +### During Development +1. Follow patterns in `CODE_STYLE_GUIDE.md` exactly +2. Use only C# 5.0 compatible syntax +3.

Verify no warnings in build output +4. Ensure tests have adequate coverage + +## Common Patterns to Follow + +### Class Creation +```csharp +// Always follow this pattern +public class NewClassName +{ + private readonly ILogger _logger; + + public Type PropertyName { get; set; } + + public NewClassName(ILogger logger, Type parameter) + { + if (logger == null) throw new ArgumentNullException("logger"); + _logger = logger; + PropertyName

this before committing: +```bash +.\verify-build.bat +``` + +### Quick Syntax Check +Common mistakes to avoid: +- Using `record` instead of `class` +- Using `string?` instead of `string` +- Using `$"..."` instead of `String.Format()` +- Using `new Dictionary<>() { ["key"] = value }` instead of `.Add()` + +## Integration Points + +### Risk Management Integration +ALL trading logic must go through: +```csharp +var riskDecision = _riskManager.ValidateOrder(intent, context, config); +if (!riskDecision.Allow) +{ + // Handle rejection + return; +} +``` + +### Logging Integration +Use the custom logging system: +```csharp +_logger.LogInformation("Operation completed: {0}", result); +_logger.LogError("Operation failed: {0}", error.Message); +``` + +## Phase 1 Specific Guidelines + +### Current Focus Areas +- NT8 adapter implementations +- Market data integration +- Order execution system +- Enhanced risk controls (Tier 2 only) + +### Do NOT Implement +- Features from Phases 2-6 +- UI components +- Advanced analytics +- Performance optimizations (until specified) + +## Quality Gates + +Every commit must pass: +1. ✅ Compilation with zero errors +2. ✅ Zero build warnings +3. ✅ All tests passing +4. ✅ C# 5.0 syntax compliance +5. ✅ Architecture compliance +6. ✅ Code style compliance + +Failure of any quality gate = automatic rejection. + +## Support and Escalation + +If you encounter: +- **Compatibility issues**: Review this configuration and guidelines +- **Architecture questions**: Check existing implementations for patterns +- **Build failures**: Run verification script and review error messages +- **Uncertainty**: Flag for human review rather than guessing + +Remember: **Maintaining NT8 compatibility is the highest priority.** When in doubt, use simpler, more

algorithmic trading framework built for NinjaTrader 8. It follows a modular architecture with a strong emphasis on risk management, position sizing, and deterministic execution. + +## Core Components + +### 1. Strategy Interface (IStrategy) +The strategy interface is the entry point for trading algorithms. Strategies are responsible for generating trading signals based on market data, but they do not handle risk management, position sizing, or order execution. + +**Key Responsibilities:** +- Process market data (bars and ticks) +- Generate trading intents based on strategy logic +- Maintain strategy-specific parameters + +**Key Methods:** +- `Initialize()` - Set up strategy with configuration +- `OnBar()` - Process bar data and generate intents +- `OnTick()` - Process tick data (optional) +- `GetParameters()` - Retrieve current parameters +- `SetParameters()` - Update parameters + +### 2. Risk Management (IRiskManager/BasicRiskManager) +The risk manager acts as a gatekeeper between strategy signals and order execution. It validates all trading intents against predefined risk parameters. + +**Key Responsibilities:** +- Validate order intents against risk parameters +- Track daily P&L and exposure +- Implement emergency halt mechanisms +- Provide risk status monitoring + +**Tier 1 Risk Controls:** +- Daily loss limits +- Per-trade risk limits +- Position limits +- Emergency flatten functionality + +**Thread Safety:** +The BasicRiskManager implementation is thread-safe using lock-based synchronization. + +### 3. Position Sizing (IPositionSizer/BasicPositionSizer) +The position sizer determines how many contracts to trade based on the strategy intent and risk parameters. + +**Key Responsibilities:** +- Calculate position size using different methods +- Apply contract clamping (min/max limits) +- Support multiple sizing algorithms + +**Sizing Methods:** +- Fixed Contracts: Trade a fixed number of contracts +- Fixed Dollar Risk: Calculate contracts based on target risk amount + +### 4. Core Models +The SDK uses a set of well-defined models to represent data throughout the system: + +**Strategy Models:** +- `StrategyMetadata` - Strategy information and requirements +- `StrategyConfig` - Configuration parameters +- `StrategyIntent` - Trading intent from strategy +- `StrategyContext` - Current market and account context + +**Market Data Models:** +- `BarData` - OHLC bar data +- `TickData` - Individual tick data +- `OrderFill` - Order execution details + +**Risk Models:** +- `RiskDecision` - Risk validation result +- `RiskStatus` - Current risk system status +- `RiskConfig` - Risk configuration parameters + +**Sizing Models:** +- `SizingResult` - Position sizing result +- `SizingConfig` - Sizing configuration parameters +- `SizingMetadata` - Sizing component information + +## Data Flow + +``` +[Market Data] → [Strategy] → [Strategy Intent] → [Risk Manager] → [Position Sizer] → [Order Execution] + ↑ ↑ ↑ ↑ ↑ ↑ + Input Signal Gen. Trade Idea Risk Control Size Calc. Execution +``` + +1. **Market Data Processing**: Strategies receive market data through the IMarketDataProvider interface +2. **Signal Generation**: Strategies analyze data and generate StrategyIntent objects +3. **Risk Validation**: All intents pass through the RiskManager for validation +4. **Position Sizing**: Valid intents are sized by the PositionSizer +5. **Order Execution**: Finalized orders are sent to the execution system (Phase 1) + +## Key Design Principles + +### 1. Risk First +All trades must pass through risk management before execution. This ensures that no trade can bypass risk controls. + +### 2. Deterministic Execution +The SDK is designed to produce identical outputs for identical inputs, making it suitable for backtesting and validation. + +### 3. Modular Architecture +Each component has a single responsibility: +- Strategies generate signals +- Risk managers control risk +- Position sizers calculate size +- Order managers execute trades + +### 4. Observability +Structured logging with correlation IDs throughout the system enables comprehensive monitoring and debugging. + +### 5.

GetTargetTicks(OrderRequest request) +{ + // Calculate target ticks for profit targets if applicable + // This would be used for strategies with predefined profit targets + return null; // Not applicable for OMS orders +} +``` + +### 2. Risk Configuration +The risk validation uses a configuration that aligns with the existing risk management system: + +```csharp +private RiskConfig GetRiskConfig() +{ + // In a real implementation, this would be configurable + // For now, using values consistent with the existing risk management system + return new RiskConfig( + DailyLossLimit: 1000, // $1000 daily loss limit + MaxTradeRisk: 200, // $200 maximum per-trade risk + MaxOpenPositions: 10, // Maximum 10 open positions + EmergencyFlattenEnabled: true // Emergency flatten functionality enabled + ); +} +``` + +### 3.
