Market Order vs Limit Order
A market order prioritizes execution, not a guaranteed price; a limit order controls price but not execution.
A market order instructs a broker or venue to execute against available liquidity without a specified price limit. It may fill at multiple prices, partially, or at a materially different price from the last quote. A limit order sets a price boundary but may remain unfilled.
Frequently Asked Questions
Does a market order execute immediately at the current price?
Not necessarily. Execution depends on market hours, routing, available depth, halts, volatility, order size, and venue rules. The displayed quote or last trade is not a guaranteed fill price.
Can a market order receive multiple fill prices?
Yes. Larger orders may consume several price levels, producing partial fills and an average execution price different from the best displayed quote.
Does a limit order guarantee execution?
No. It limits the acceptable price but may not fill, may fill only partially, or may lose queue priority as prices move.
How are stop orders different?
A stop order generally becomes a market or limit order after a trigger condition. Trigger rules, gaps, slippage, and venue handling can cause outcomes that differ from the stop price.
