Order book
An order book is a list of buy and sell orders for a specific security or financial instrument, organized by price level. It shows the number of shares or units that traders want to buy and sell at different prices and is used to determine the market depth and liquidity of a particular security. The order book is crucial for determining the current market price of a security and helps traders to make informed decisions about when to buy or sell a security. The order book is a fundamental component of any trading platform and is used by traders, brokers, and market makers to execute trades and optimize their strategy.
