What it is
Marketdata maintains a shadow orderbook per symbol rebuilt from ME WAL events (INSERT, CANCEL, FILL) via the replication subscription. It broadcasts L2 depth snapshots (20 levels), BBO updates, and a trade tape (200-entry rolling window) to public WebSocket subscribers. Not on the order critical path.
