RiskPicksWhat is a Liquidity Sweep?
A liquidity sweep is when price moves rapidly through a level where resting orders are clustered (stop losses, limit orders) and then reverses. The sweep "takes" the liquidity at that level. It is the same thing as a stop hunt, just described from the perspective of the liquidity rather than the stops.
Where liquidity sits
- Below support levels: stop losses from long traders sit just below support. These are sell orders waiting to be triggered
- Above resistance levels: stop losses from short sellers sit just above resistance. These are buy orders waiting to be triggered
- At swing highs and lows: traders place stops behind recent turning points. Every visible swing high or low on the chart has orders behind it
- At round numbers: psychological levels like $50, $100, $200 attract both stops and limit orders
Why sweeps happen
Large orders need liquidity to get filled. A fund trying to buy 500,000 shares cannot just hit the ask because it would move the price against them. They need a large number of sell orders hitting the market at once. A cluster of triggered stop losses provides exactly that.
Reading sweeps on the chart
- Quick wick below support: a candle with a long lower wick (tail) that briefly broke support means the sweep happened and buyers stepped in
- Volume spike on the sweep: the triggered stops create a burst of volume. If price reverses on that volume, the sweep is likely complete
- Multiple sweeps: sometimes price sweeps a level more than once before the real move. Each sweep takes more liquidity
Smart money does not chase price. It waits at levels where it knows orders will be triggered, then trades against the resulting flow. Understanding this changes how you read every chart.
