The Liquidity Sweep: Signal or Noise?

A liquidity sweep occurs when price briefly moves beyond a visible level and then returns inside the same candle, leaving a wick that extends past the level before closing back within the prior range.

What the pattern is

The sweep is a single-candle move that trades over a level and immediately reverses, closing back inside the range it just left. The wick that extends beyond the level is the part traders call the sweep; the close inside the range is what distinguishes it from a simple breakout.

What forms it

Price must first reach a level that many participants can see on the chart. Once that level is in place, a quick push beyond it draws stops or breakout orders. When those orders are filled, the market reverses within the same candle, leaving the wick above or below the level and a close back inside the prior range.

What confirms it

Three conditions must be met before the move is treated as a sweep rather than noise. The candle must close back inside the range, the level itself must have been visible beforehand, and the reversal must be obvious only after the candle is complete. Without these three elements the move is simply another wick, not a sweep.

How it fails

Calling every reversal a sweep is the common error. If no clear, widely visible level exists first, there is nothing for price to sweep; the wick is then just normal price action rather than a liquidity event.
