Best Execution, Trading Capacity, and Quotations

Quick Answer

Best execution requires reasonable diligence to find the best market for a customer order and seek the most favorable price under prevailing conditions. A broker-dealer acts as an agent for a customer or as a principal for itself. A stated-price quotation must be honored under its stated conditions, unless the member immediately revises the size after completing an in-progress transaction.

Order handling, capacity disclosure, and quotation practices each answer a different question about a transaction.


What Does Best Execution Require?

  • Best execution requires reasonable diligence to ascertain the best market for a customer order.
  • The member then buys or sells in that market so the resulting price is as favorable as possible under prevailing market conditions.
  • Order-entry and execution practices govern how orders are entered and executed.

Exam Tip: Gotchas

  • Best execution is a diligence standard, not a price guarantee. The member must use reasonable diligence to ascertain the best market and make the price as favorable as possible under prevailing market conditions. A worse price is not automatically a violation.

Is the Broker-Dealer Acting as Agent or Principal?

Trading capacity identifies the role the broker-dealer takes in the transaction.

CapacityBroker-dealer role
Agent capacityExecutes a transaction on behalf of a customer.
Principal capacityBuys or sells for the broker-dealer's own account.

Think of it this way: An agent is a messenger carrying out the customer's transaction. A principal is one of the transaction's parties because the firm is trading from its own account.

What Must a Firm's Quotation Represent?

RequirementWhat it means
Stated-price offerA member offering to buy or sell at a stated price must be prepared to trade at that price and under those stated conditions, unless the member immediately revises the size after completing an in-progress transaction.
Published transaction reportThe member must believe the reported transaction was a bona fide purchase or sale.
Published quotationThe member must have reasonable cause to believe the quotation is bona fide, is not fictitious, and has no fraudulent, deceptive, or manipulative purpose.
Quotation definitionA quotation includes any bid or offer. It also includes a formula, such as "bid wanted" or "offer wanted," designed to induce a person to make or submit a bid or offer.
Multiple quotation mediumsReal-time priced quotations for an OTC equity security must be the same in each real-time medium used, unless the customer-limit-order exception applies.
  • Members may change inter-dealer quotations in the ordinary course of trading. At the time of an offer, the member must be prepared to trade at the stated price and conditions.
  • A member that is already effecting a transaction in the quoted security when an order arrives may communicate a revised quotation size immediately after that transaction. The member is then not obligated to trade beyond the revised size.

Exam Tip: Gotchas

  • Best execution concerns handling a customer order. A stated-price offer concerns the firmness of the firm's own quotation.
  • Transaction reports and quotations use different publication standards. The member must believe a reported transaction was a bona fide purchase or sale. A quotation requires reasonable cause to believe it is bona fide, not fictitious, and free of any fraudulent, deceptive, or manipulative purpose.
  • A quotation can be more than a displayed price. Any bid, offer, or formula designed to induce a bid or offer is a quotation.
  • Ordinary quotation changes do not erase firmness. Members may change inter-dealer quotations during ordinary trading, but each offer must be firm at its stated price and conditions.
  • Firmness has one size exception. A member already effecting a transaction in the quoted security may communicate a revised quotation size immediately after that transaction. The member then owes only the revised size, not the earlier one.
  • The customer-limit-order exception applies only to quotation alignment. The same-quotation requirement has a narrow customer-limit-order exception; it is not permission to publish inconsistent proprietary quotations.

What Should You Check on Exam Day?

  • Identify whether the firm acts for the customer or for its own account.
  • Require a stated-price offer to be firm under its stated conditions, unless the member communicates a revised size immediately after completing a transaction already in progress.
  • Distinguish ordinary-course inter-dealer quotation changes from a failure to honor the terms stated when an offer was made.
  • Require reasonable cause to believe a quotation is bona fide, not fictitious, and has no fraudulent, deceptive, or manipulative purpose.
  • Align real-time OTC equity quotations across mediums unless the customer-limit-order exception applies.
