Obvious levels — the prior-day high and low, round numbers, session extremes — have clusters of stop orders resting just beyond them. A liquidity sweep is when price spikes just past such a level to trigger those stops (grabbing the liquidity), then reverses. It's the mechanism behind the stop-run reversal, framed around a specific level.
Why sweeps happen
Large participants need liquidity to fill size, and the resting stops beyond an obvious level provide it: a push above the prior-day high triggers breakout buys and short stops, creating a burst of buying that a big seller can offload into — then price, having grabbed the fuel, reverses. The sweep looks like a breakout but is really a liquidity grab. Recognizing it is the difference between being the trapped buyer and trading the reversal.
How to trade it
The tell is a sharp spike past the level and an immediate reclaim back — a long wick beyond the prior-day high, then price back below it fast, with no acceptance beyond. Entry: the reclaim (fade the swept high with puts). Target: VWAP, the range middle, or the opposite level — trapped breakout traders fuel the reversal. Stop: a new high beyond the sweep — acceptance means it was a real break, not a sweep.
A spike past the prior-day high that snaps right back isn't a breakout — it's the market grabbing stops. Fade the sweep, stop beyond the wick.
The context
Sweeps-and-reversals are cleanest in a positive-gamma regime where levels are defended and breakouts fail. In a trend day, what looks like a sweep can be a genuine break that runs — so require the fast reclaim, not just a poke. Sweeps target resting liquidity, so they cluster at the most obvious levels. NoVo's mapped levels show where the stops (and the sweeps) are likely to be.
