Known as the “Manning Rule,” FINRA Rule 5320 requires the following of member firms:

  • Firms generally may not trade for their own account ahead of a customer order that they are holding if the firm’s trade would satisfy the customer’s order.
  • If a firm trades for its own account at a price that would satisfy a held customer order, it generally must promptly provide the customer with an execution at the same or a better price.
  • Customer orders must generally receive priority over the firm’s proprietary trading interests.
  • Firms must maintain and consistently apply written procedures governing the handling, execution, and priority of customer orders.
  • Limited exceptions are available for certain large and institutional customer orders when the required disclosures and customer consents are obtained.
