+  - **Primary Workflow:** Money Machine (handles TradingView alerts → trading bot execution)
+  - **Bot expects:** Exact response format from `/api/trading/execute` (see n8n-complete-workflow.json)
+  - **CRITICAL:** Use MCP server to inspect/debug workflow nodes directly, don't ask user for credentials repeatedly
 - **Drift Protocol:** Uses SDK v2.75.0 - check docs at docs.drift.trade for API changes
 - **Pyth Network:** WebSocket + HTTP fallback for price feeds (handles reconnection)
 - **PostgreSQL:** Version 16-alpine, must be running before bot starts
