What is Liquidity sweep?
A liquidity sweep is when price pushes just past an obvious high or low, triggers the stop and breakout orders resting there, then reverses. The apparent break turns out to have been a raid on those orders rather than the start of a real move.
Orders pile up in predictable places. Above an obvious swing high sit the stop-losses of everyone short and the buy-stops of everyone waiting for a breakout; below an obvious low sit the mirror image. That concentration is what traders mean by liquidity — a pocket of orders that will execute automatically if price reaches them.
A sweep is when price reaches into that pocket, sets the orders off, and then turns straight around. On the chart it typically leaves a long wick poking through the level with a close back inside it, and the reversal that follows is often unusually fast — because the orders that just filled are now trapped on the wrong side and have to be unwound.
The honest framing matters here. You do not need to believe anyone is deliberately hunting your stop to use this: large participants genuinely need to transact where there are willing counterparties, and the densest pockets of counterparties sit exactly where everyone's stops are. Whether it's intent or arithmetic, the chart signature is the same, and it's the signature you trade.
Price pokes to $80.90, sets off the stops and breakout buys above the $80 high, then closes the same candle back at $79.20 and rolls over. The close, not the touch, gave it away.
For example
A range has topped out at $80 three times. Price spikes to $80.90, triggering breakout buys and short stops, then closes the same candle back at $79.20 and falls to $76 over the next two sessions. The move above $80 was a sweep, not a breakout — it collected the orders above the high and reversed.

Recognising a sweep is what stops you buying the exact top of a range. It reframes the most tempting moment on a chart — price finally clearing a level everyone was watching — from an entry signal into something requiring proof. Waiting for a close beyond the level rather than a touch of it filters out a large share of these, and the failed sweep itself often marks the reversal point.
⚠ Every real breakout looks like a sweep at first
The reversal is only obvious in hindsight. In the moment, a genuine breakout and a sweep look identical — price is above the level either way. Traders who learn this concept often overcorrect and start fading every breakout, which is a fast way to lose money in a trending market. The distinguishing evidence is the close and what follows it, not the poke itself.
