Orderbook

Subscribe to the channel name orderbook:<symbol> to get real-time orderbook updates.

The initial snapshot will send all the open orders in the orderbook sorted by price on bids (lowest to highest) and on asks (lowest to highest). A non-decreasing sequence number is returned on each update.

Orderbook updates are keyed by price level. Orderbook data is returned as:

{'market_id': 'BTC-USD', 'bids': [[price, size], ...], 'asks': [[price, size], ...], 'sequence': 9097270, 'timestamp': 1665996854}

If the bid size at the price level 19,800 changed to 10.2, the bids field would be [[19800, 10.2]]. If there are no more bids at the price level 19,800, then the bids filed would be [[19800, 0]].

Each orderbook update increments sequence number by +1. If you have skipped a sequence number, you must resubscribe to get the most accurate orderbook state.
