What Is a Liquidity Sweep?
A liquidity sweep is when price pushes through an obvious level, such as a session high or low, triggers the stop orders resting beyond it, and then reveals whether the market accepts or rejects those new prices. It is information about the auction, not an instruction to trade.
Definition
Liquidity is resting orders. Stops from traders positioned the other way, entry orders from traders waiting for a breakout, and passive orders from larger participants all cluster around the same visible places: the overnight high and low, the prior-day high and low, the session open, round numbers. A sweep is the moment price trades through one of those places and consumes the orders sitting there.
The mechanics, step by step
- Stops rest beyond a level. Say NQ has held its overnight low all morning. Traders long from the range have stops just below that low. Traders wanting a short breakout have sell stops there too.
- Price runs through the level. Enough selling arrives to push under the low. The resting stops trigger, adding more selling. Price accelerates for a moment because those orders are executing at market.
- The auction decides. Once the resting orders are consumed, one of two things happens. Either new sellers are willing to keep trading below the low, and price holds there (acceptance). Or the selling was only the stops, buyers absorb it, and price comes back through the level (rejection).
Step three is the whole game. Steps one and two happen at every important level, every session. They tell you nothing by themselves.
Sweep vs breakout: how to tell them apart
At the instant price crosses the level, a sweep and a breakout look identical. The difference only appears afterward.
A sweep that rejects
Price spikes through the level, often on a single wide-range candle, and closes back inside the prior range within a few bars. Follow-through in the direction of the break fails. Structure on the lower timeframe flips back the other way.
A breakout that accepts
Price crosses the level, pulls back toward it, and the pullback holds. Candles begin closing beyond the level. Time spent beyond it builds. The old level starts acting as the opposite kind of level.
Useful checks: Did price close beyond the level or just wick through it? Did the pullback hold or fail? Did the move show displacement, meaning a fast, decisive candle, or did it drift? Displacement back inside the range points to rejection. Displacement that continues beyond the level points to acceptance.
Why a sweep is information, not a signal
The most common way to lose money with this concept is to treat every sweep of a low as a buy and every sweep of a high as a sell. That is a bet on rejection before the auction has shown rejection. Sometimes the low is swept and price simply keeps going because the market has more to sell. The sweep did not fail as a concept; the trader skipped the evidence step.
A sweep changes the map. It tells you a pool of liquidity has been used, where price now sits relative to the range, and which outcome you should be watching for. What it does not do is grant permission to enter.
Doctrine
Knowing the destination is not the same as knowing the entry. The overnight low was always a destination. The sweep confirms price got there. Only acceptance or rejection tells you what to do about it.
How AuraBot handles sweeps
Anchor Rails, AuraBot's location engine, tracks session highs and lows, prior-day high, low and close, and registers when price sweeps one of them. That updates where price is relative to the important areas. On its own, it does not change execution permission.
SKELETON then reads what the auction does at the swept level: displacement, structure, acceptance or rejection. Black Book evaluates whether current conditions permit an entry. The shared backend reconciles all three into one state for the instrument. A sweep typically moves the state from WAIT to WATCH. It moves toward ARMED only when evidence of acceptance or rejection arrives. Until then, the state waits, because the market has not decided yet either.
Questions
Which levels get swept most often on NQ and Gold?
The overnight high and low, the prior-day high and low, and the London session extremes on Gold. These are visible to every participant, so orders cluster there.
How long should I wait after a sweep before deciding?
Until the auction gives evidence: a close back inside the range, or a pullback that holds beyond the level. On NQ during the New York session that is often a handful of candles, but the evidence matters more than the clock.
