When price moves beyond a key level to trigger stop losses and pending orders before reversing.
A liquidity sweep occurs when price pushes past a significant high or low — where clusters of stop losses sit — then quickly reverses. Institutional traders need liquidity (orders on the other side) to fill large positions. By sweeping stops above a high or below a low, they create the volume needed to enter their real positions in the opposite direction.
Understanding liquidity sweeps helps traders avoid being stopped out by institutional manipulation and instead trade alongside smart money. Many false breakouts are actually liquidity sweeps. Recognizing them transforms a stop-loss trigger into a high-probability entry signal.
Price has bounced off $100 support three times. Everyone’s stop losses are sitting just below $100. Price dips to $99.50, triggering all those stops, then immediately reverses and rallies to $110. The sweep below $100 was institutional traders collecting liquidity to fuel the move higher.
Price sweeps below support to trigger stop losses, then reverses sharply upward — a classic liquidity sweep.
