Order Book

Live list of all open buy and sell orders for a trading pair.

An order book matches bids (buy orders) against asks (sell orders) at decreasing/increasing prices. The matching engine fills crossing orders. Centralized exchanges run order books in their own infrastructure; some DEXs (dYdX, Hyperliquid) replicate the model on-chain.
