Liquidity Sweep: Equal Highs, Lows and the Order Book
Guide · October 31, 2026"Liquidity" is one of the most-used words in Smart Money Concepts (SMC) and ICT content, and one of the vaguest. This guide gives you a definition you can check on a chart: what a liquidity sweep is, how equal highs and equal lows are found with clear rules, what an order book heatmap adds, and the limits that matter before you rely on any of it.
What "liquidity" means on a chart
Here liquidity means resting orders: stop-losses, breakout entries and limit orders waiting at a price. They cluster at obvious places:
- just above a high that was tested twice,
- just below a low that was tested twice,
- around round numbers and the previous day's or week's high and low.
What is a liquidity sweep?
A liquidity sweep happens when price trades through one of those obvious levels and takes the orders resting beyond it. The classic picture: two equal highs form, price spikes a little above them, then falls back below. Keep two things apart:
- The sweep itself is a fact: price traded beyond the level.
- What happens next is not part of the definition. Sometimes price reverses (a "stop hunt"); often it simply keeps going.
How to define equal highs and lows (so it's repeatable)
- Find swings with a fixed lookback: a swing high is higher than the n candles on each side (default n = 3).
- Compare consecutive swing highs. If two are within a small tolerance (default 2 pips), they form an equal-highs (EQH) level at the higher one. Equal lows (EQL) work the same way, at the lower one.
- Mark the sweep. The level stays open until a later candle's high trades above it (or its low below it, for EQL).
| Setting | Default | Why it matters |
|---|---|---|
| Swing | 3 | Larger values find fewer, more significant levels. |
| Tol. pips | 2 | How "equal" two highs must be. Too wide and every pair qualifies. |
| Extend bars | 20 | How far the level is drawn to the right. |
- A swing is only confirmed n candles later. A tool that draws an equal-highs line before both swings were confirmed is using information you didn't have.
- Wick vs close. A sweep is a trade through the level, so a wick counts. A close beyond it is a different, stronger event.
What an order book heatmap adds
Equal highs and lows are an inference about where orders probably sit. An order book heatmap shows where limit orders actually sit, drawn under the candles through time. You will see price pause at a bright band, trade through it, or watch the band disappear before price gets there: the orders were pulled. That is why a heatmap is context, not a map of certain reactions. Order books are public on crypto exchanges; for FX and CFDs there is no single public book, while equal highs and lows work on any market.
How traders use liquidity levels
- Planning where an idea is wrong: a cluster of equal highs above a long is where price may be drawn; above a short, it's where your stop is most exposed.
- Reading context after a sweep: did price close back inside the range, or beyond it and keep going? Combine it with market structure (BOS/CHoCH).
- Avoiding the obvious stop: a stop exactly at an equal high or low sits where everyone else's is.
Honest limits
A sweep is a description, not a prediction. Log 50 sweeps on your market and timeframe and count how often price reversed versus continued, then compare with random bars. Parameters change the picture, examples in videos are chosen in hindsight, and order books can be pulled. We apply the same honesty to our own tools: we tested our combined Total Score walk-forward with fees, and it did not predict direction better than chance. See the result.
In PrimeScope
- Liquidity (EQH/EQL) is one of the Pro Tools: equal highs and lows with the rules above, computed on the server on real prices, with each sweep marked. It is part of the Smart Money and ICT presets, next to market structure, order blocks, fair value gaps and previous day/week levels.
- Liquidity Heatmap (crypto): the Binance order book drawn under the candles through time, with order book bars on the right edge. Free on BTCUSD; other crypto pairs are part of the Pro plan.
- In the Trainer the Pro Tools work on real history with the future hidden, so you can practise reading sweeps the way they look live.
FAQ
What is a liquidity sweep in trading?
It's when price trades through an obvious level, such as equal highs or equal lows, where stop and breakout orders are likely resting, and takes those orders. It describes what happened; it doesn't say whether price will reverse.
What are equal highs and equal lows?
Two consecutive swing highs (or lows) at almost the same price. Because they look like an obvious level, stops and breakout orders tend to cluster just beyond them.
Is a liquidity sweep the same as a stop hunt?
A stop hunt is a sweep followed by a reversal. Many sweeps are not followed by a reversal; price simply continues. So every stop hunt is a sweep, but not every sweep is a stop hunt.
What does a liquidity heatmap show?
Where limit orders are resting in an exchange's order book, drawn through time under the price chart. It's available where the order book is public, such as on major crypto exchanges.
Can a liquidity heatmap predict where price will go?
No. Orders can be added or pulled at any moment. Use it as context on where size is sitting, not as a forecast.
Can I practise reading liquidity sweeps without risking money?
Yes. In the PrimeScope Trainer you replay real history candle by candle with the future hidden, plan each trade in R and get a Discipline Score. No broker, no deposit.
