Order Book
trading
A real-time list of buy and sell orders organized by price level on an exchange.
The order book aggregates limit orders into bids and asks, forming market depth. Trades match when a market order crosses the spread or when opposing limits meet.
Traders use order books to assess liquidity, slippage risk, and potential breakout levels.
