Development and Testing
This document covers development practices, testing methodologies, and backtesting capabilities for the Signal trading system. It provides guidance for developers working on system enhancements and performance analysis.
For information about the core trading pipeline implementation, see Trading Components. For details about specific agent implementations, see Agent System Reference.
Development Workflow
The Signal system uses a modern TypeScript-based development stack with Bun as the primary runtime and build tool. The development process emphasizes rapid iteration and comprehensive testing of trading strategies.
Build System Architecture
Development Build Pipeline
Testing Strategy
The system employs multiple testing approaches to ensure trading algorithm reliability:
| Testing Type | Purpose | Implementation |
|---|---|---|
| Backtesting | Historical performance validation | BACKTEST.md analysis reports |
| Unit Testing | Component-level verification | TypeScript test suites |
| Integration Testing | End-to-end workflow validation | AI agent response testing |
| Performance Testing | System load and response time | Real-time trading simulation |
Development Environment Setup

Code Quality Standards
The codebase follows strict TypeScript standards with emphasis on:
- Type Safety: Full TypeScript implementation across all services
- Modular Architecture: Service-oriented design with clear separation of concerns
- Error Handling: Comprehensive error logging and recovery mechanisms
- Performance Monitoring: Real-time metrics collection and analysis
