Sales Order Book 3 PLY NCR

An sales order book is the list of orders (manual or electronic) that a trading venue (in particular stock exchanges) uses to record the interest of buyers and sellers in a particular financial instrument. A matching engine uses the book to determine which orders can be fully or partially executed.

In securities trading an order book contains the list of buy orders and the list of sell orders. For each entry it must keep among others, some means of identifying the party (even if this identification is obscured, as in a dark pool), the number of securities and the price that the buyer or seller are bidding/asking for the particular security.

An sales order book might also refer to a business’s list of open, unshipped, customer orders, normally time-phased and valued at actual individual order prices, that may include margin and profitability analysis.
