Liquidity Sweeps: The Trigger Behind Every CRT
A liquidity sweep is the moment price runs through a prior extreme — a high or low where stop orders rest — collects those orders, and shows its hand. Liquidity sweep trading is built on one observation: markets move toward resting orders, and what price does immediately after taking them tells you more than the move itself. In Candle Range Theory, the sweep is not one signal among several. It is the trigger. No sweep, no setup.
This article defines the sweep precisely — precisely enough to code — and covers the two outcomes that follow it, plus the one case where you stand aside.
Where the liquidity sits
Stops cluster at obvious places. A trader short below a swing high puts the stop above that high. Breakout traders put buy orders above the same high. So above every visible high sits a pool of buy orders waiting to be filled. Mirror it below every visible low: stops from longs, plus breakdown sell orders. That is resting liquidity, and it is not a metaphor — it is real order flow parked at predictable prices.
This is why the street name for the event is a stop hunt. A push through a high fills two crowds at once: the shorts getting stopped and the breakout buyers getting in. Stop hunt trading and liquidity sweep trading describe the same thing from two angles — the hunt is the mechanism, the sweep is the event you can define and test.
What counts as a sweep — the exact rule
Wick level. A sweep happens the moment a candle's wick touches or exceeds the prior extreme. Not the body. Not the close. The wick.
And equal price counts. If a wick reaches exactly the old high — to the tick — that high is swept. The boundary is inclusive. A touch is a take.
The strictness is the point. Stops resting at a level get filled at that level; the market does not owe you a clean break beyond it. If your definition demands "a few pips through," you will mark sweeps inconsistently, and any backtest built on inconsistent marking is fiction. One rule, applied everywhere: touch or exceed, wick level, equality counts.
Sweep-and-reclaim vs sweep-and-go
After the wick takes the level, there are two outcomes, and they are opposites.
Sweep-and-reclaim. The candle takes the extreme and closes back inside the prior range. The push had enough fuel to collect the stops and nothing more. The level held; the wick was the grab. This is the reversal case — and the only case CRT trades.
Sweep-and-go. The candle takes the extreme and closes beyond it. That is not a sweep that failed. That is expansion: price wanted the level and kept it. The range is finished, and the breakout candle becomes the new reference. Fading this is the most expensive habit in range trading — shorting a high because it got "swept" when the market simply broke out.
The dividing line between the two is a closing price. Nothing else.
Wicks trigger, closes decide
This split is the core of disciplined sweep trading, so it is worth stating plainly.
The wick matters for the trigger because the wick is where the business happened. The stops were at the extreme; the wick is proof they were taken. A candle that closed near the level but never touched it took no liquidity, however dramatic it looked.
The close matters for confirmation because it is the market's settled opinion. Intrabar, nearly every sweep looks like a reversal at some point. The close is the first honest answer to whether the reclaim held.
In CRT terms: the wick crossing the extreme births a potential setup, live but unproven. The candle closing back inside the range confirms it. Closing outside kills it — and any rules-based system records that as expansion, not as a reversal that almost worked.
The dual sweep — when both sides go
The warning case: a single candle takes out both the high and the low of the range. An outside bar. Both pools of liquidity collected in one bar.
There is no clean directional read here. Whichever side was swept first, the run to the other side already reached what would have been the target — the entire setup lived and died inside one candle. And when both crosses print so close together that the order cannot be determined on your entry timeframe, there is no tradeable direction, and no trade fires.
The rule: stand down. A dual sweep consumes the range, the outside bar becomes the new reference, and you wait for the next one. Treating a both-sides sweep as a directional signal is guessing with extra steps.
The sweep is step one of every CRT
Candle Range Theory turns sweep logic into a complete setup. The parent candle defines the range — and therefore which high and low hold the liquidity that matters. The sweep is the trigger. The close back inside is the confirmation. The order block left behind at the sweep is the entry, and the opposite side of the range is the target. The full ruleset is in the CRT trading strategy guide; the lineage from broader ICT liquidity concepts is in CRT vs ICT.
Most traders mark sweeps after the fact, when every reversal looks obvious. The real test is whether your sweep definition is mechanical enough to run on live data without you standing over it.
Watch sweeps fire in real time
CRT Terminal runs this exact logic as a live detection engine — wick-level sweeps with inclusive boundaries, confirmation closes, dual-sweep handling — on real market data, with frame-by-frame replay and backtesting, so you can see every sweep the rules flagged and what happened next. A terminal, not a charting app.

FAQ
What is a liquidity sweep?
A liquidity sweep is when a candle's wick touches or exceeds a prior high or low where stop orders rest, filling those orders. Equal price counts — a wick reaching the exact level is a sweep.
Is a liquidity sweep the same as a stop hunt?
Same event, different emphasis. "Stop hunt" describes the mechanism — price moving to where stops rest. "Liquidity sweep" describes the structural event you can define precisely and test.
How do you tell a liquidity sweep from a breakout?
The close. A sweep takes the level and closes back inside the prior range; a breakout takes the level and closes beyond it. If you trade the wick without waiting for the close, you cannot tell the two apart.
Why do wicks matter more than closes in sweep trading?
The wick is where the stops were filled, so the wick defines the trigger. The close then decides whether the sweep confirms a reversal or was just expansion. They answer different questions.
What is a dual sweep?
One candle taking out both the high and the low of the reference range. There is no reliable directional read, so rules-based sweep trading stands aside and waits for the next range.
