- Watcher: polls Data API for trader activity - Executor: buy/sell with market orders + retry logic - Position manager: JSON-based state tracking - Auto-sell: limit orders at profit target - Redeemer: check & redeem winning positions on-chain - Config: env-based settings with validation - DRY_RUN mode for safe testing
