When Is a Trader More Likely to Use a Market Order despite the Cost of the Bid-Offer Spread?

A trader will use a market order when immediate execution is prioritized over price certainty. This is common during periods of high volatility, when a quick entry or exit is crucial to capitalize on a fleeting opportunity or to manage risk rapidly.

For example, a trader might use a market order to execute a stop-loss to prevent further losses, accepting the spread cost.
