Market Order vs Limit Order Interview Guide
Market order vs limit order interview guide comparing urgency, price control, fill certainty, adverse selection, examples, and decision rules.
Candidates explaining urgency, price control, and fill uncertainty.
Market orders prioritize completion
A market order is useful when urgency or completion risk dominates, but the trader gives up price control and may cross the spread.
Limit orders prioritize price
A limit order can avoid paying through a price limit, but it introduces non-fill risk, queue risk, and adverse-selection risk.
Concrete example
If news just invalidated a position, a market order may beat waiting passively; if urgency is low, a limit order may reduce expected cost.
The best choice depends on context
Use urgency, spread, volatility, depth, order size, alpha decay, queue position, and risk limits to compare the two choices.
Common mistakes
Candidates often say market orders are bad and limit orders are good. The real tradeoff is certainty versus price control.
