LiquidityLevelsLiquidity Sweep
A liquidity sweep is a move that pushes slightly beyond an obvious high or low, triggers the orders resting there, and then reverses back inside. It is a description of what price did at a level.

What a liquidity sweep is
Certain price levels attract orders: stops from traders positioned against the level and breakout orders from traders waiting for it to give way. Prior highs, prior lows, equal highs and lows, and session extremes all collect such orders. Traders refer to those resting orders as liquidity.
A sweep happens when price trades just beyond such a level, which executes those orders, and then quickly returns. The pattern on a chart is usually a wick through the level and a close back on the original side. The wick is the sweep.
Sweep versus breakout
A breakout is a move beyond a level that holds. A sweep is a move beyond a level that does not. The difference shows up afterward: after a breakout, price stays and trades beyond the level, building time and volume there. After a sweep, price returns inside soon after and often travels away from the level in the other direction.
You cannot tell them apart in real time with certainty. Traders watch for clues such as how fast price returns, whether the candle closes back inside, and what volume appears at the extreme. This is the same distinction the Academy draws between acceptance and rejection, and a sweep is closely related to a failed auction.
Where sweeps are commonly seen
Popular targets include the prior day high and low, the overnight high and low, equal highs and equal lows, and the high or low of the Asia or London session. A frequent story in index futures is that London sweeps the Asia high or low early in its session, and then the market moves the other way, although it is only one of several outcomes.
The frequency of sweeps depends on how you define a level and a sweep. With enough levels on a chart, price will touch some of them nearly every day, which makes the pattern easy to find in hindsight.
How traders use the idea
Some traders wait for a sweep and a reversal back inside the level before considering an entry in the opposite direction, using the extreme of the sweep as a reference for risk. Others use the idea defensively: if a level looks obvious, they expect it may be run before a move and avoid placing stops right beyond it.
Neither approach is a guarantee. Sweeps can turn into breakouts, with price continuing in the direction of the sweep, and many levels are never swept at all.
A simple way to practice
Mark the prior high and low and the overnight high and low each morning. Note each time price pokes beyond one and record the close of the candle and what the next hour did. Separate the cases where price returned inside quickly from those where it stayed beyond. After a month you have a personal sample of how often your market sweeps versus breaks.
Worked example
Common mistakes
- Calling every wick a sweep. A sweep needs a level that attracted orders and a return inside.
- Assuming a reversal is guaranteed after a sweep. Some become breakouts.
- Ignoring the timeframe: a sweep on a one-minute chart can be a minor event on the hourly.
- Hindsight bias. With many levels marked, most days contain something that looks like a sweep.
How it connects to ES, NQ, SPY and QQQ
ES and NQ sweep prior highs and lows regularly in the overnight session. The probe levels translate to SPY and QQQ by dividing by roughly 10 and 41, and the briefing lists key levels in both terms so a trader can see where the sweep levels sit in ETF prices.
LiquidityLevels briefings note how price reacted around key levels, including whether a probe beyond a level was accepted or rejected.

This idea is applied to the current ES and NQ overnight structure every session.
