Liquidity sweeps and stop hunts

Few experiences in trading are as frustrating as this one: your stop-loss gets hit by a quick spike, and then price moves exactly the way you expected. Traders call it a stop hunt. In ICT and "smart money" terminology the same event is described more neutrally as a liquidity sweep. This guide explains what liquidity means in this context, where it tends to sit, what a sweep looks like on a chart, how to tell a sweep from a genuine breakout, and how traders use the idea without falling into the trap of seeing conspiracies behind every wick.

What "liquidity" means here

In everyday market language, liquidity means how easily something can be bought or sold. In ICT-style analysis the word is used more specifically: it refers to clusters of pending orders that sit at predictable prices. Two kinds matter most:

• Stop-loss orders. Traders who are long usually place stops just below a recent low. Traders who are short place them just above a recent high. When price reaches those levels, the stops turn into market orders: sell orders below lows, buy orders above highs.
• Breakout orders. Traders waiting for a breakout place buy orders just above resistance and sell orders just below support.

Both kinds cluster around the same obvious places. The orders resting above a high are often called buy-side liquidity, and the orders resting below a low sell-side liquidity.

Where liquidity tends to sit

If you ask where most traders would place their stops, the answers are rarely surprising. That predictability is the whole point:

• Equal highs and equal lows. Two or more swing points at almost the same price look like strong support or resistance, so many stops gather just beyond them.
• The previous day's, week's or session's high and low. These levels are watched by a very large number of participants.
• Obvious trendlines. Stops often sit just beyond a trendline that has been touched several times.
• Round numbers. Psychological levels attract both stops and pending orders.

What a sweep looks like

A sweep has two parts: a push through the level, and a failure to stay there.

1. Price approaches an obvious high (or low) where liquidity is likely resting.
2. It trades through the level, often with a quick spike, triggering the stops and breakout orders beyond it.
3. Instead of continuing, it fails to hold beyond the level and closes back inside the previous range. On a single candle this often leaves a long wick through the level.

Why sweeps happen

The common explanation is about finding the other side of a trade. Someone who wants to sell a large position needs plenty of buyers. The stop orders of short sellers and the breakout orders of new buyers, both sitting just above an obvious high, provide exactly that. When price pushes into that cluster, those orders fill, and a large seller can use them as the counterparty.

You do not have to believe that someone is deliberately "hunting" your stop for this to be useful. Stops cluster at predictable levels, reaching those levels produces a burst of orders, and once that burst is absorbed there may be little left to push price further in the same direction. That is enough to explain why sharp reversals often start right after an obvious level is taken out.

Sweep or genuine breakout?

Every breakout starts by trading through a level, so a push through a high is not a sweep on its own. The difference shows in what happens next:

• Acceptance vs rejection. A breakout usually closes beyond the level and holds there. A sweep closes back inside.
• Follow-through. After a breakout, price tends to keep building beyond the level. After a sweep, it moves back into the old range, often quickly.
• Market structure. A sweep followed by a break of a recent opposing swing point (for example, a sweep of a high followed by a break of the last higher low) is read as a stronger reversal signal than the wick alone.
• The larger trend. A push through a high in a strong uptrend is more likely to be a real breakout than one inside a range or against the higher-timeframe direction.

Waiting for the candle to close is the simplest discipline here. Mid-candle, sweeps and breakouts look identical.

How sweeps connect to other concepts

A sweep on its own tells you that stops were taken, not what happens next. It becomes more useful when it links with other ideas:

• The sharp reversal after a sweep often leaves a fair value gap behind, showing that the move away was one-sided.
• The last opposing candle before that reversal can be marked as an order block, an area traders watch in case price returns to it.
• Session highs and lows are common sweep targets. Many ICT-based approaches pay particular attention to the first sweep of the prior session's high or low after a major market opens.

A worked example

A hypothetical example with made-up prices on a five-minute chart:

1. Yesterday's high was 18,420.00, and price tested it twice this morning without breaking it. Those two tests are equal highs, so stops and breakout orders are probably resting just above.
2. At the New York open a candle spikes to 18,428.50, trades above the level, then closes at 18,414.25, back below yesterday's high. That candle is a sweep candidate.
3. The next candle closes below the last higher low at 18,402.00, a shift in structure against the push up.
4. A trader who uses sweeps now has a defined story: buy-side liquidity was taken, price was rejected, and structure turned. They still decide under their own rules whether any trade is justified.

If the spike candle had instead closed at 18,426.00 and the next candle had held above 18,420.00, the same move would read as a breakout, and the sweep idea would be wrong.

Common mistakes

• Calling every wick a sweep. A sweep needs an obvious level with a clear reason for orders to sit beyond it.
• Acting before the close. Until the candle closes, you cannot tell a sweep from a breakout.
• Fading every breakout. Some pushes through a level are genuine, especially in the direction of a strong trend.
• Placing your own stop in the obvious spot. Understanding where liquidity sits is also a reason to think carefully about where your own stop is, and what it would mean if it were hit.
