In simple terms
Liquidity grab is an informal label for a quick move through a previous high, low, or another obvious level, followed by a return. The interpretation is that executable interest existed beyond the level: limit orders, aggressive orders, or triggered stops.
The chart shows movement and completed transactions, not a complete map of intent. Some orders may not be visible in the public order book, and each venue has its own rules.
How it is interpreted
A precise description should state the crossed level, speed of the move, return, and any available volume or depth data. Saying only that “liquidity was taken” does not identify who traded or why.
The term often overlaps with stop hunt, but they are not perfect synonyms: liquidity grab may involve several types of interest, while stop hunt puts stop orders at the center of the interpretation.
Limit
A quick cross may result from legitimate orders, news, low liquidity, or a temporary imbalance. A spike and return do not by themselves prove institutional flow, deliberate stop hunting, or manipulation.
