failure recovery) + +--- + +## Design Principles + +1. **Separation of Concerns**: Decision-making (Agent) vs. execution (Trading Service) +2. **Reusability**: Backtesting can reuse agent logic +3. **Testability**: Agent logic can be tested independently +4. **Scalability**: Agent can be scaled independently of Trading Service +5. **Maintainability**: Clear boundaries between components +6. **Observability**: Comprehensive metrics and logging +7. **Resilience**: Graceful degradation and error handling + +--- + +## Risk Mitigation + +### Technical Risks +- ML service latency → Cache predictions, use stale data if needed +- Trading service downtime → Queue orders, retry with exponential backoff +- Database bottleneck → Index optimization, read replicas, caching +- Strategy logic errors → Extensive testing, paper trading validation +- Order submission failures → Idempotent retry, comprehensive error handling + +### Operational Risks +- Configuration errors → Schema validation, default values, dry-run mode +- Resource exhaustion → Resource limits, monitoring alerts +- Data corruption → Database transactions, audit logging +- Version incompatibility → API versioning, backward compatibility + +--- + +## Alternatives Considered + +| Alternative | Decision | Rationale | +|-------------|----------|-----------| +| Embed agent logic in Trading Service | ❌ Rejected | Violates SRP, harder to test, couples decision-making with execution | +| Use message queue instead of gRPC | ❌ Rejected | Added complexity for MVP, can add later if needed | +| Agent as library, not service | ❌ Rejected | Limits reusability (backtesting needs it) | + +--- + +## Future Enhancements (Post-MVP) + +1. **Advanced Allocation Strategies**: + - Black-Litterman allocation + - Hierarchical risk parity + - Reinforcement learning-based allocation + +2. **Multi-Account Support**: + - Manage multiple trading accounts + - Cross-account risk aggregation + +3. **Regime Detection**: + - Automatic strategy switching based on market regime + - Volatility regime detection + +4. **Advanced Rebalancing**: + - Tax-aware rebalancing + - Transaction cost optimization + +5. **Strategy Marketplace**: + - User-defined strategies + - Strategy backtesting UI + - Strategy performance leaderboard + +--- + +## Summary + +**Trading Agent Service** is a critical new component that orchestrates trading decisions by managing universe selection, asset selection, portfolio allocation, and strategy coordination. It **drives** the Trading Service by generating and submitting orders based on ML predictions, market conditions, and risk constraints. + +**Key Achievement**: Clear separation of concerns between decision-making (Agent) and execution (Trading Service), enabling independent testing, scaling, and reusability across backtesting and live trading. + +**Estimated Implementation Time**: 8 weeks (1 developer) +**Risk Level**: Medium (new service, but clear interfaces) +**Status**: ✅ **DESIGN COMPLETE - READY FOR IMPLEMENTATION** + +--- + +**Document Status**: ✅ **COMPLETE** +**Last Updated**: 2025-10-16 +**Agent**: 11.10 diff --git a/docs/AGENT_11.16_QUICK_REFERENCE.md b/docs/AGENT_11.16_QUICK_REFERENCE.md new file mode 100644 index 000000000..f5c5ff1b6 --- /dev/null +++ b/docs/AGENT_11.16_QUICK_REFERENCE.md @@ -0,0 +1,192 @@ +# Agent 11.16 - Trading Agent Proxy - Quick Reference + +**Date**: 2025-10-16 +**Status**: ✅ **COMPLETE** + +--- + +## What Was Done + +Added Trading Agent Service proxy to API Gateway with **zero-copy forwarding** for all 15 service methods. + +--- + +## Files Created + +1. `services/trading_agent_service/proto/trading_agent.proto` (616 lines) +2. `services/api_gateway/src/grpc/trading_agent_proxy.rs` (550+ lines) +3. `docs/AGENT_11.16_TRADING_AGENT_PROXY_SUMMARY.md` +4. `docs/AGENT_11.16_QUICK_REFERENCE.md` (this file) + +--- + +## Files Modified + +1. `services/api_gateway/build.rs` (+13 lines) +2. `services/api_gateway/src/lib.rs` (+8 lines) +3. `services/api_gateway/src/grpc/mod.rs` (+5 lines) +4. `services/api_gateway/src/grpc/server.rs` (+178 lines) + +**Total**: ~1,370 lines added + +--- + +## Architecture + +``` +TLI → API Gateway (50051) → Trading Agent Service (50055) +``` + +**Proxy Features**: +- ✅ Zero-copy message forwarding +- ✅ Connection pooling (Arc-based Channel) +- ✅ Streaming support (StreamAgentActivity) +- ✅ Circuit breaker config (implementation pending) +- ✅ TLS/mTLS support +- ✅ <10μs routing overhead target + +--- + +## 15 Service Methods + +### Universe Management (3) +1.
