A registered representative must complete which of the following activities when entering a discretionary trade?

FINRA Rule 3260 requires that discretionary trades be approved by the customer in writing and reviewed by the supervising firm. The order ticket must indicate that discretion was exercised to ensure proper oversight.

B is correct because marking the order ticket ensures compliance with supervisory requirements.

A is incorrect because discretionary authority is not limited to market orders.

C is incorrect as discretionary trades do not require pre-approval for each trade but require prior written authorization.

D is incorrect because discretionary authority allows the RR to decide on price and timing without specific customer instructions.
