A liquidity sweep happens when price runs through an obvious high or low, triggers orders around that area, and then reveals whether the move had real continuation behind it.

Why sweeps happen

Obvious highs and lows attract stops, breakout entries, and defensive positioning. That concentration creates liquidity.

A move through those levels can therefore do two things at once:

• collect flow from obvious positioning
• test whether the market truly wants to continue

What a sweep can look like

• a fast wick through a prior high or low
• a brief breakout with little follow-through
• a sharp move followed by immediate rejection

The key is not the sweep itself. The key is what price does after the sweep.

Stop clusters as observation areas

Many traders place defensive orders near the same obvious areas: prior highs, prior lows, neckline zones, wick extremes, or clean structure boundaries. Those clusters can help explain why price sometimes pushes slightly beyond a level before deciding whether to continue or reject.

A stop cluster is an observation area, not a stop-placement recommendation. Do not use this idea to decide where a stop should go. Use it only to ask:

• where might reactions concentrate?
• did price accept beyond the area or reject back through it?
• did the sweep change structure, or only create a quick wick?

This keeps the focus on visible market behavior rather than guessing where other traders placed orders.

Sweep or true break?

Ask:

• did price accept beyond the level?
• did structure improve in that direction?
• was there strong follow-through, or just a quick grab and reversal?

This is where BOS vs MSS becomes useful.
