DEBIT AND CREDIT SLIP
20. As soon as the transaction is accepted by the broker, he gives to the customer a debit or credit slip showing the nature of the transaction, or it is sent by mail, as soon as possible after business hours; the charge or credit depend upon whether it is a purchase or a sale. The blanks for this purpose, as shown in Fig. 3, should be printed on different colored paper; the debit blank is usually on white and the credit blank on buff or yellow paper. If a client buys, the amount of his purchase appears as a debit to his account, with the commission added. He receives credit for whatever amount of margin he deposits, and the account stands thus until delivery, when the entire balance must be paid. If a sale is made by the client before the time of delivery, the amount of the sale is credited to his account, less the commission due for selling and any other charges. The difference in the account, whether it is an amount due from the broker to the client or from the client to the broker, is paid in cash as soon as the deal is closed.
