betting_combat.trading.market_data

Book tops and recent traded volume for the decision engine.

The WebSocket mirror answers when it is current; otherwise a REST snapshot is taken on the spot. Either way a book is “as of” a moment the exchange confirmed it, and a market that cannot be read is simply absent (the engine records book_missing) — a data problem can cost a trade, never cause a wrong one.
