Liquidity sweep
Volume Profile Analysis glossary · Auction Theory & Market Profile (TPO)
Definition
A sharp spike in price driven by stop-order cascades rather than by genuine directional conviction; typically reverses quickly.
Liquidity sweep in plain English
Lots of traders leave "stop" orders — automatic exit instructions that fire if price hits a certain level to cap their losses. A liquidity sweep is when price stabs sharply into a cluster of those stops, triggering them all at once, which forces a rush of orders that shoves price even further in a quick chain reaction. The key insight: this spike isn't real buyers or sellers who believe in the move — it's just machinery tripping over itself. That's why a sweep usually snaps back fast once the stops are exhausted, leaving a sharp "fakeout" wick behind.
