An order book is a list containing all outstanding orders on a specific currency pair. It lists all the orders placed by buyers and sellers at each price point. This is called the market depth. An order to buy is called a ‘bid’ and an order to sell is called a ‘sell’. The exchange’s matching engine pairs up all bid and asks, resulting in trades occurring.
