🎯 FINAL HANDOFF SUMMARY
|
||||
You now have 5 complete artifacts that provide everything needed for autonomous AI implementation:
|
||||
1. Repository Setup Package
|
||||
|
||||
Complete directory structure
|
||||
All starter files (.gitignore, Directory.Build.props, etc.)
|
||||
Solution and project creation commands
|
||||
NuGet package setup
|
||||
|
||||
2. Core Interfaces Package
|
||||
|
||||
All interface definitions (IStrategy, IRiskManager, IPositionSizer)
|
||||
Complete model classes (StrategyIntent, StrategyContext, etc.)
|
||||
Comprehensive unit tests
|
||||
Test data builders
|
||||
|
||||
3. Risk Management Package
|
||||
|
||||
Complete BasicRiskManager.cs implementation
|
||||
All Tier 1 risk controls (daily limits, trade limits, position limits)
|
||||
Thread-safe implementation with locks
|
||||
Comprehensive test suite with scenario testing
|
||||
Validation scripts
|
||||
|
||||
4. Position Sizing Package
|
||||
|
||||
Complete BasicPositionSizer.cs implementation
|
||||
Fixed contracts and fixed dollar risk methods
|
||||
Contract clamping and multi-symbol support
|
||||
Extensive test suite with calculation validation
|
||||
JSON test data with expected results
|
||||
|
||||
5. Complete Validation Script
|
||||
|
||||
End-to-end Phase 0 validation
|
||||
Automated success criteria checking
|
||||
Detailed reporting with next steps
|
||||
Pass/fail determination for Phase 1 readiness
|
||||
|
||||
🤖 HOW TO USE WITH YOUR AI AGENTS
|
||||
Simply give each AI agent one package at a time with this instruction format:
|
||||
For Archon (Step 1):
|
||||
Task: Set up NT8 SDK repository foundation
|
||||
Use the attached "Repository Setup Package"
|
||||
Follow every step in the setup instructions exactly
|
||||
Validate: Repository builds successfully with 0 warnings
|
||||
For Kilo (Step 2):
|
||||
Task: Implement all core interfaces
|
||||
Use the attached "Core Interfaces Package"
|
||||
Create every file exactly as specified in the implementation checklist
|
||||
Validate: All unit tests pass with >85% coverage
|
||||
And so on through all 5 packages.
|
||||
✅ SUCCESS INDICATORS
|
||||
|
||||
Green Light: AI agent reports task complete, validation passes
|
||||
Yellow Light: AI agent asks clarifying questions, validation has warnings
|
||||
Red Light: AI agent stuck >4 hours, validation fails
|
||||
|
||||
🚨 IF PROBLEMS OCCUR
|
||||
|
||||
AI agent reports errors: Give them the validation script to run and fix issues
|
||||
AI agent stuck: Switch the task to the other AI agent
|
||||
Validation fails: Have AI agent re-read the specific requirements and try again
|
||||
|
||||
🎉 FINAL RESULT
|
||||
After all 5 packages are complete, you'll have:
|
||||
|
||||
Complete Phase 0 implementation (2-3 weeks of traditional development in days)
|
||||
Institutional-grade risk management that prevents dangerous trades
|
||||
Professional position sizing with multiple methods
|
||||
Comprehensive test suite ensuring reliability
|
||||
Production-ready foundation for Phase 1 advanced features
|
||||
|
||||
Your AI agents now have everything they need to autonomously deliver a professional trading system. The specifications are complete, tested, and ready for execution.

## **SUCCESS CRITERIA**
|
||||
|
||||
✅ **BasicPositionSizer.cs implemented exactly as specified**
|
||||
✅ **Fixed contracts sizing method working correctly**
|
||||
✅ **Fixed dollar risk sizing method with proper rounding**
|
||||
✅ **Contract clamping applied (min/max limits)**
|
||||
✅ **Multi-symbol support with accurate tick values**
|
||||
✅ **Comprehensive test suite with >90% coverage**
|
||||
✅ **All calculation examples produce exact expected results**
|
||||
✅ **Configuration validation prevents invalid setups**
|
||||
✅ **Error handling for edge cases (zero stops, invalid intents)**
|
||||
|
||||
## **CRITICAL REQUIREMENTS**
|
||||
|
||||
1. **Exact Calculations**: Must match calculation examples precisely
|
||||
2. **Conservative Rounding**: Always round down (floor) for contract quantities
|
||||
3. **Proper Clamping**: Apply min/max contract limits after calculation
|
||||
4. **Symbol Support**: Support all specified symbols with correct tick values
|
||||
5. **Error Handling**: Handle invalid inputs gracefully
|
||||
6. **Deterministic**: Same inputs must always produce same outputs
|
||||
|
||||
**Once this is complete, position sizing is fully functional and ready for integration with the strategy framework.**

# NT8 Institutional SDK
|
||||
|
||||
Professional-grade algorithmic trading SDK for NinjaTrader 8, built for institutional use with comprehensive risk management and deterministic execution.
|
||||
|
||||
## 🚀 Quick Start
|
||||
|
||||
### Prerequisites
|
||||
- .NET 6.0 SDK
|
||||
- Visual Studio Code + Docker Desktop (recommended)
|
||||
- Git
|
||||
|
||||
### Setup (5 minutes)
|
||||
```bash
|
||||
# Clone repository
|
||||
git clone <repository-url>
|
||||
cd nt8-institutional-sdk
|
||||
|
||||
# Verify setup
|
||||
dotnet build && dotnet test
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🏗️ Architecture Principles
|
||||
|
||||
- **Risk First**: All trades pass through risk management before execution
|
||||
- **Deterministic**: Identical inputs produce identical outputs for testing
|
||||
- **Modular**: Strategies are thin plugins, SDK handles infrastructure
|
||||
- **Observable**: Structured logging with correlation IDs throughout
|
||||
|
||||
## 📊 Current Status: Phase 0 Development
|
||||
|
||||
### ✅ Completed
|
||||
- Development environment and tooling
|
||||
- Core interfaces and models
|
||||
- Basic project structure
|
||||
|
||||
### 🚧 In Progress
|
||||
- Risk management implementation
|
||||
- Position sizing algorithms
|
||||
- Basic strategy framework
|
||||
- Comprehensive unit testing
|
||||
|
||||
### 📅 Next (Phase 1)
|
||||
- Order management system
|
||||
- NinjaTrader integration
|
||||
- Market data handling
|
||||
- Advanced testing and validation

||||
```
|
||||
|
||||
### **Step 4: Add Required NuGet Packages**
|
||||
|
||||
```bash
|
||||
# Add packages to NT8.Core
|
||||
dotnet add src/NT8.Core/NT8.Core.csproj package Microsoft.Extensions.Configuration
|
||||
dotnet add src/NT8.Core/NT8.Core.csproj package Microsoft.Extensions.Configuration.Json
|
||||
dotnet add src/NT8.Core/NT8.Core.csproj package Microsoft.Extensions.Logging
|
||||
dotnet add src/NT8.Core/NT8.Core.csproj package Microsoft.Extensions.DependencyInjection
|
||||
dotnet add src/NT8.Core/NT8.Core.csproj package Newtonsoft.Json
|
||||
dotnet add src/NT8.Core/NT8.Core.csproj package FluentValidation
|
||||
|
||||
# Add test packages
|
||||
dotnet add tests/NT8.Core.Tests/NT8.Core.Tests.csproj package FluentAssertions
|
||||
dotnet add tests/NT8.Core.Tests/NT8.Core.Tests.csproj package Bogus
|
||||
dotnet add tests/NT8.Core.Tests/NT8.Core.Tests.csproj package Moq
|
||||
|
||||
dotnet add tests/NT8.Integration.Tests/NT8.Integration.Tests.csproj package FluentAssertions
|
||||
dotnet add tests/NT8.Integration.Tests/NT8.Integration.Tests.csproj package Bogus
|
||||
dotnet add tests/NT8.Integration.Tests/NT8.Integration.Tests.csproj package Moq
|
||||
```
|
||||
|
||||
### **Step 5: Validation**
|
||||
|
||||
Run this command to verify everything is set up correctly:
|
||||
|
||||
```bash
|
||||
dotnet build --configuration Release
|
||||
```
|
||||
|
||||
**Expected Result:** Build succeeds with 0 warnings and 0 errors
|
||||
|
||||
If you see any errors, check:
|
||||
1. All directories were created correctly
|
||||
2. All files were copied to the right locations
|
||||
3. .NET 6.0 SDK is installed
|
||||
4. All NuGet packages were added successfully
|
||||
|
||||
## **SUCCESS CRITERIA**
|
||||
|
||||
✅ Repository structure matches specification exactly
|
||||
✅ All starter files are in correct locations
|
||||
✅ Solution builds successfully with 0 warnings
|
||||
✅ All NuGet packages are properly referenced
|
||||
✅ CI/CD pipeline configuration is in place
|
||||
|
||||
**Once this is complete, you're ready for Step 2: Core Interfaces**
