A liquidity sweep is a trader's description of price moving beyond a visible level—such as equal highs, equal lows, or a prior swing—and then rejecting or returning through that level. Traders watch these areas because stop orders and breakout orders may cluster around obvious prices. A sweep is an interpretation of price behavior; a chart alone does not reveal every participant's orders.

Sweep or breakout?
A brief move beyond a level followed by a close back inside the range may support a sweep interpretation. Sustained trading and acceptance beyond the level may instead support a breakout interpretation. One candle cannot reliably settle the question in every market; observe follow-through and use a pre-defined confirmation method.
Common errors
Do not label every failed breakout a deliberate stop hunt. Do not enter immediately just because price crossed a high or low. Consider trend context, volatility, session conditions, and where your trade idea would be invalidated. A sweep can continue into a genuine breakout, and reversals can fail.
Backtest objective definitions—for example, how far price must cross a level and how quickly it must reclaim it—rather than relying on hindsight labels.
