Street Book

DEFINITION of 'Street Book'

A daily account of futures commission merchants and clearing members. The street book gives details on each futures transaction, including the date, type of commodity, price and the affected market. The street book also records the name of the person for whom the trade was made.


The street book is maintained in order to determine what investors owe and to whom. In other words, it is like an itemized bill. It contains all the pertinent data required for clearance purposes. Maintaining a street book is also a crucial element in computing an investor's Adjusted Debit Balance, which determines how much he/she can purchase on margin.
