Regulatory Notice 26-11
FINRA is publishing updated interpretations of its margin rule (FINRA Rule 4210) to provide guidance to members in implementing the new intraday margin standards. Correspondingly, FINRA is deleting all interpretations relating to the former day trading margin requirements, which the new intraday margin standards have replaced in their entirety. Also, FINRA has made available educational resources, which members can share with customers, that provide information about the new intraday margin standards and margin accounts.
