Customer-order questions ask you to connect instructions with the firm’s duties. Start by identifying the customer’s order and the firm’s proposed action. Then consider best execution, customer-order protection, and market-wide requirements separately.
Is best execution the same as order protection?
No. FINRA Rule 5310 governs best execution. Rule 5320 restricts proprietary trading ahead of customer orders, subject to its conditions and exceptions. Regulation NMS adds separate quotation and trading requirements.
A scenario can require more than one analysis. Do not stop after finding that one rule permits an action. Ask whether another duty still affects the customer’s order. Study the conditions of each exception rather than treating “an exception exists” as permission for unrelated conduct.
What facts should you mark in a question?
Identify the order side, price, size, product, time, and any special customer instructions. Then identify whether the firm acts for itself or a customer and whether it holds another order that matters.
Suppose a firm holds a customer buy order and proposes to buy the same equity security for its own account. The next question is not simply whether the firm has enough capital. You need to examine the customer-order protection rule and its conditions. Changing the price can change the analysis. A claimed lack of knowledge is not enough by itself: Rule 5320’s no-knowledge exception requires effective internal controls, such as appropriate information barriers, and has different conditions for NMS stocks and OTC equity securities.
How should you study Regulation NMS?
Keep quote display, access, and trade-through protection distinct. The SEC’s Regulation NMS FAQ explains protected quotations and the conditions of Rules 610 and 611. Begin with the scope of the rule and the kind of quotation involved. A question about a displayed price may be testing whether the quotation qualifies for protection, not just whether another price looks better.
Use the written lesson to learn the exceptions and their factual triggers. Do not generalize an exception from a short example to every trade. When a question changes a venue’s systems status or an order’s designation, explain exactly why that fact matters.
How can you test your understanding?
Work through the customer-order practice set, then change one fact in each missed scenario. Return to the customer obligations lesson when you cannot explain the result.
