Review best execution, order handling, routing supervision, and execution controls tested in the trading portion of Series 24.
This section tests whether the principal can supervise order flow from entry through execution. Series 24 expects awareness of best execution, order-routing controls, customer-order protection, supervisory review of exceptions, and the market-structure logic that shapes how orders should be handled. The exam is not asking whether a trader can route an order quickly. It is asking whether the principal can prove the process protects the customer and produces reviewable evidence.
The common trap is to treat routing as a convenience choice. Principal-level questions usually turn on whether the firm’s routing pattern, execution quality, and exception handling are being monitored in a way that supports customer interest rather than speed, habit, or internal preference.
| Supervision point | What the principal should look for | Common Series 24 trap |
|---|---|---|
| Order entry controls | Customer instructions, order details, restrictions, and account status are captured correctly before routing. | Treating a bad input as a trader error instead of a process-control issue. |
| Routing logic | The firm’s routing path reflects best-execution review and not just convenience or venue habit. | Assuming a fast venue is automatically the best venue. |
| Customer-order protection | Customer orders are handled in a way that preserves required protections and does not favor firm convenience. | Thinking best execution and customer-order protection are separate topics. |
| Exception review | Outlier fills, recurring venue issues, and execution-quality breaks are visible and escalated. | Waiting for complaints before reviewing execution quality. |
| Documentation | The firm can show what was reviewed, what exception was found, and what change followed. | Fixing one event without leaving a supervisory trail. |
Series 24 rewards the answer that protects the customer and strengthens the review process at the same time. A principal who only reacts to the last bad fill is weaker than one who asks why the routing pattern was allowed to drift in the first place.

The principal’s job is to supervise the system, not just to judge a single trade after the fact. Once a pattern appears, the better answer is almost always process review and remediation.
A firm’s routing pattern begins showing execution-quality concerns for customer orders. What is the principal’s best response?
A. Ignore the pattern if the venue remains fast
B. Review the routing and execution process under the firm’s supervisory controls and best-execution obligations
C. Continue the pattern unless customers file complaints
D. Let each trader decide individually whether the issue matters
Answer: B. Series 24 expects principals to supervise execution quality through a control process. Speed alone does not satisfy best-execution obligations, and recurring concerns should trigger review before customer harm becomes formal.
