Understanding Liquidity Zones

In SMC terms, liquidity refers to areas where a large number of pending orders are likely resting — commonly just above a recent swing high (where short-sellers' stop-losses sit) or just below a recent swing low (where buyers' stop-losses sit).

Because triggering those stops provides the volume needed to fill large institutional orders, price will sometimes push just beyond an obvious high or low — a move often called a "liquidity sweep" — before reversing in the opposite direction.

This is why the most obvious high or low on a chart isn't always the safest place to put a stop-loss, and why some traders treat a sweep of an old high/low followed by a sharp reversal as a higher-probability signal than the raw breakout itself.
