Integrating a broker into OpenAlgo

Golden rule: OpenAlgo has a common symbol format, common API, and common WebSocket format. Your only job per file is to translate the broker's specific shapes into those common contracts (and back). Copy the closest reference broker, then adapt the broker-specific bits.

36 broker plugins already exist. Almost every problem you will hit has been solved in one of them — the skill is knowing which one to copy, and which details are genuinely broker-specific.

Where broker code sits in the stack

restx_api/<endpoint>.py     Marshmallow schema validation + per-IP rate limit. Thin.
  services/<x>_service.py   Auth resolution, analyze-mode branch, event emission.
                            Returns (success: bool, response_data: dict, status_code: int)
    broker/<name>/api/*     <- YOU ARE HERE. The only place broker specifics live.
