Investopedia explains 'Street Book'


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.
