Whipsaw

A whipsaw is a sharp price movement that moves just far enough to trigger stop losses or signal entries before abruptly reversing in the opposite direction. It is one of the most frustrating experiences in trading — you were right about the direction, but the market shook you out before moving your way. Whipsaws are especially common in choppy, range-bound markets where there is no clear trend, and around high-impact news events where initial reactions are often reversed within minutes. They can also occur at key technical levels (support, resistance, round numbers) where clusters of stop losses sit — price pushes through the level, triggers the stops, then reverses back. Some traders and institutions deliberately target these stop clusters, a practice sometimes called "stop hunting" or "liquidity sweeps." Whipsaws affect both sides: long traders get stopped below support only to see price rally, and short traders get stopped above resistance only to see price fall. The psychological damage of being whipsawed repeatedly can lead to widening stops excessively, removing stops entirely, or abandoning a sound strategy — all of which create worse long-term outcomes than the occasional whipsaw loss.
