An order book that displays the available buy and sell orders for a specific security at different price levels.
Market depth, also known as the order book, provides a real-time view of the liquidity of a financial instrument by showing the number of shares or contracts bid (buy) and offered (sell) at various price points. It helps traders gauge the immediate supply and demand, potential price support and resistance levels, and the ease with which large orders can be executed without significantly impacting the price.
