Data
Data is where everything starts — this page watches the database (Neon usage, every table's size and schema) and every external data source feeding it, so upstream problems surface before they poison signals or execution.

Data Source monitoring
Health is inferred from DB signals: snapshot freshness, service heartbeats, error events in the last 60 minutes. Streaming (WebSocket) sources: the execution service order flow, browser-direct market data, and the Arb data backbone (ibkr-feed · hl-book · binance-feed · md-recorder); the rest is REST polling.
