Question 1. A customer places a market order to buy 100 shares of XYZ. The current quote is $25.10 bid / $25.15 ask, and this is the NBBO. The customer should expect to execute at approximately:
- $25.10
- $25.125 (the midpoint)
- $25.15
- Any price within the spread, at the broker's discretion
Show answer and explanation
Correct answer: C. A market buy order fills at the ask; a market sell order fills at the bid. Best-execution rules require the broker to seek the most favorable terms reasonably available, but the customer is not entitled to midpoint pricing on a standard retail market order.
