A liquidity sweep (or stop raid) is when price spikes through a pool — grabbing the stops — and then snaps back. It's the single most important trigger in Smart Money Concepts, and the reason so many "perfect" breakouts fail.
The anatomy of a sweep:
- Price approaches an obvious high (buy-side liquidity).
- It wicks through, triggering the stops and breakout buyers.
- There's no follow-through — instead, a strong reversal (often with displacement and a Change of Character).
- The trapped traders now fuel the move the other way.
