Liquidity Sweep (Stop Hunt)
The Formal Definition
A market occurrence where large institutions or algorithmic market makers push asset prices beyond key support or resistance levels to trigger clusters of retail stop-loss orders, absorbing the resulting liquidity.
Target Zone = Obvious Swing High/Low ± Retail Stop-Loss Cluster
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Ever wonder why a stock dips just far enough to hit your stop-loss by three cents before violently reversing to all-time highs? You weren't unlucky; you were part of a liquidity sweep. Retail traders place stops at the exact same obvious chart levels, and algorithms treat those clusters like an open buffet."

Real-World Example: Scenario Breakdown
Examining the real numbers for: Forex pair EUR/USD with major visible support at 1.0800
| Execution Metric | Smart-Money Risk Buffer | Textbook Retail Stop |
|---|---|---|
| Fee / Rate | Standard ECN trade | $0.00 app trade |
| Spread / Buffer | Placed stop outside the obvious pool (1.0768) | Placed stop exactly at 1.0798 (2 pips under support) |
| Execution / Status | Wick swept to 1.0782 and bounced hard | Stopped out at the bottom of the institutional wick |
| Total Cost / Result | +120 pips profit captured | Forced out right before the market reversed upward |
How Brokers Weaponize This Term
B-Book dealing-desk brokers can see internal client stop-loss concentration levels. During thin pre-market liquidity, internal platform quotes can briefly decouple from public exchange feeds, triggering stop runs against client positions.

How can retail traders avoid getting caught in liquidity sweeps?
Place stop-loss orders beyond obvious chart support/resistance levels, use average true range (ATR) buffers, or wait for market structure confirmation before entering.
Do brokers deliberately hunt their own clients' stops?
Unregulated offshore brokers have been documented manipulating synthetic feeds; however, in lit markets, liquidity sweeps are driven by institutional algorithms seeking order flow.
