What Is Whipsaw?
A whipsaw occurs when price triggers a stop-loss or entry in one direction, then immediately reverses and moves in the opposite direction. You get stopped out of a long just before price rockets upward, or you enter a breakout just before it reverses. The name comes from the back-and-forth cutting motion of a whipsaw blade.
How Whipsaw Works
Whipsaws are most common during choppy, range-bound markets and around news events where volatility spikes in both directions. They're also prevalent around key technical levels where stop clusters exist on both sides — price pierces one level (triggering stops), reverses to pierce the other level (triggering opposite stops), creating two consecutive false signals.
Why It Matters for Traders
Minimizing whipsaw damage requires: wider stops that accommodate noise (ATR-based rather than arbitrary), waiting for candle closes to confirm breaks (rather than entering on intracandle wicks), reducing position sizes during choppy conditions, and accepting that some whipsaws are unavoidable — they're the cost of having stops in place at all.
