Security Notes

The server uses environment variables for configuration, including potential API keys for exchanges (though not passed in the provided `CCXTClient` instantiation example, it supports them). No hardcoded secrets, `eval` usage, or obfuscation were found in the provided code snippets. The async architecture, robust error handling with retries and timeouts, and rate limiting contribute to its resilience against network issues and API abuse. A deeper audit of `config.py` and full credential handling would be needed for a perfect score, but the structure is sound.
