Rule 15c1-7, 17 CFR 240.15c1-7 (Discretionary Accounts)

The Commission adopted Rule l5c1-7 in 1937 (17 CFR 240.l5c1-7) to protect the public from broker-dealers that transact unauthorized trades. The rule provides that any act of a broker-dealer designed to effect securities transactions with or for a customer account over which the broker-dealer (directly or through an agent or employee) has discretion will be considered a fraudulent, manipulative, or deceptive practice under the federal securities laws, unless a record is made of the transaction immediately by the broker-dealer. The record must include (a) the name of the customer, (b) the name, amount, and price of the security, and (c) the date and time when such transaction took place.
