I've noticed that many traders confuse two similar but completely different phenomena on charts — liquidity grab and liquidity sweep. Let's clarify, because understanding these is really important for grasping the behavior of large market players.

Let's start with liquidity grab — it's the fastest and most abrupt price movement. Usually, it's a single candlestick pattern with a long wick that swiftly breaks through a key level — support or resistance — to trigger retail traders' stop-loss orders. Then, the price reverses just as quickly. It looks like a sharp spike on the chart. Liquidity grab happens literally within minutes, and its goal is to quickly liquidate retail traders' orders.

On the other hand, liquidity sweep is a calmer, more measured movement through an area where many orders are accumulated. It involves several candles, often with pauses before a reversal. Large traders use this approach when they need to execute a large volume of trades without sharp jumps that could spook the market.

The key simple difference: liquidity grab is a sharp spike on the chart, sweep is wave-like movement. One is quick and aggressive, the other slow and methodical. If you see a sharp breakout of a level with a reversal on the FIL or BB chart — that's most likely a liquidity grab. If the price moves through an area gradually with multiple attempts, look for a liquidity sweep.

It's useful to know this because it helps distinguish manipulation from a real trend. Once you understand these mechanics, it becomes easier to predict what will happen next.
