Liquidity Sweep Patterns: Identifying Stop Runs

A liquidity sweep (stop run) is a deliberate move beyond an obvious level to trigger stop orders, then a reversal. These are the highest-probability reversal setups in modern price-action trading — when identified correctly.

The mechanics of a sweep

Liquidity sits in two places:

• Above equal highs: buy stops from short sellers.
• Below equal lows: sell stops from long buyers.

Market makers and large traders target these stops to fill large orders without slippage. The move beyond the level triggers stops, providing the liquidity for institutional entries in the opposite direction.

The sweep pattern: spike beyond the level → triggers stop → snaps back inside → reversal.

Pattern identification

A valid sweep has four components:

1. Obvious liquidity level. Equal highs/lows, prior session high/low, daily high/low, weekly open, round number. The level must be visible to retail — that's where the stops cluster.
2. Spike beyond the level. A wick or single candle pierces the level. The break is fast, not gradual.
3. Fast reclaim. Price snaps back inside the level within 1–5 candles. The faster the reclaim, the higher the probability.
4. Reversal candle. A confirmation candle (engulfing, pin bar, strong opposite close) prints at or just inside the level.

Without all four, it's not a sweep — it's a real break.

High-probability sweep setups

Common high-quality sweeps: the Asia-session range sweep (London sweeps the Asian high/low then reverses; 60–65% win rate on EURUSD/GBPUSD); equal-highs sweeps (price spikes above a double top and closes back below — short on reclaim, stop 1–2 ticks above the wick); daily-high sweeps on ES/NQ in the first hour; and trendline sweeps (break fails to hold, trade with the original trend).

Entry, stop, target

• Entry: on the close of the reclaim candle, or on the next candle's open after a strong reversal candle.
• Stop: 1–3 ticks beyond the sweep extreme — tight, which is the R:R advantage.
• Target: the opposite liquidity pool. R:R typically 1:3 to 1:5 because of the tight stop.

Filters, invalidation, and risk

• Higher timeframe alignment: sweeps against the HTF trend fail more often; a bullish sweep at HTF support works, at HTF resistance is risky.
• Volume on the sweep candle ≥ 1.5× average confirms stop triggering; sweeps at session opens are higher-quality.
• Invalidation: price holds beyond the level for 3+ candles (real break), or no reversal candle within 5 candles.
• Cap sweep trades at 1% risk; never average into a sweep entry. Avoid sweeps on stocks with earnings pending — gap risk invalidates the tight-stop structure.

Sweep trading is pattern recognition plus discipline. The pattern is common; the discipline to wait for all four components is rare.
