What is Liquidity Sweep?

A quick push through an obvious high or low that triggers resting stops, then reverses — collection, not continuation.

A liquidity sweep is a fast move through an obvious level — equal highs, equal lows, a previous day's extreme, a trendline — that triggers the stop losses and breakout orders resting there, and then reverses. The push exists to collect those orders, because institutions filling large positions need counterparties, and clusters of resting stops are exactly where counterparties wait. What looks like a failed breakout to a retail trader is often a completed collection to the participant who engineered it.

The signature of a sweep is speed and rejection: price spikes through the level, spends little time beyond it, and closes back inside the prior range, frequently leaving a long wick. Sweeps are among the highest-value events in the Smart Money Concepts framework because they tell you where the fuel came from and often precede the real move in the opposite direction. A sweep of a major low followed by a bullish change of character is one of the cleanest reversal sequences a trader can learn to recognise.
