Code Review
This is a massive and impressive pull request that adds significant production-ready features to the TradingAgents platform. The introduction of multi-LLM support, paper trading via Alpaca, a web UI with Chainlit, and Docker deployment are all major steps forward. The code is generally well-structured, and the extensive documentation and test suite (89% coverage on new broker code) are commendable. My review identified one critical security vulnerability in the docker-compose.yml file related to the Jupyter service's default token, and a medium-severity concern in the .chainlit configuration regarding unrestricted file uploads. Addressing these points will ensure the platform is secure and robust for production use.
