Nasdaq wicks eleven points below yesterday's low, further than the whole prior thirty minutes of trading, then reverses so hard it closes the same candle back above the level with room to spare. Nothing fundamental changed in that minute. What happened is that a cluster of resting stop orders sat just below yesterday's low, price ran down to collect them, and once they were filled there was nobody left to sell, so the market snapped back. That sequence, a deliberate looking run through an obvious level followed by an immediate reversal, is the liquidity sweep, and it is one of the more mechanically explainable reversal setups available.
The setup is popular right now, which means it also gets abused: plenty of traders now call any wick a sweep after the fact, which is just pattern matching in reverse. A genuine sweep has specific characteristics before you know how the story ends.
What resting liquidity actually is
Any obvious level, yesterday's high or low, a round number, a well marked swing point, accumulates two kinds of orders nearby: stop losses from traders positioned on the wrong side of a potential break, and breakout orders from traders hoping to catch a new move if the level gives way. Both sit as resting orders just beyond the level, waiting to be triggered. When price finally reaches that level with enough force to trigger them, that cluster of orders gets filled in a rush, which is exactly the kind of one directional volume burst that can look, briefly, like the start of a real breakout.
Recognizing a genuine sweep
Three things separate a real sweep from an actual breakout. First, speed: a sweep typically happens fast, often within a single candle or two, rather than building gradually. Second, the reversal: a genuine sweep reverses hard and immediately, closing back on the original side of the level within the same candle or the very next one, while a real breakout tends to hold and build on the new side. Third, context: sweeps happen most reliably at obvious levels with a lot of resting orders behind them, prior day extremes and clean round numbers, rather than obscure lines nobody else is watching. A wick with no fast reversal and no obvious level behind it is not a sweep. It is just a wick.
The reclaim entry
The entry is not the sweep itself, it is the reclaim: waiting for price to close back on the original side of the swept level before acting. Entering during the wick, guessing the reversal before it confirms, means entering into the exact volatility that just ran your own kind of stop. The reclaim candle's close is the trigger, the swept level's extreme is the invalidation, and the stop sits just beyond that extreme, since a genuine sweep should not need to be revisited once it reverses.
A worked sweep on Nasdaq
Yesterday's low sits at 19,140. This morning, Nasdaq wicks down to 19,129, eleven points through the level on heavy one minute volume, then closes the same candle back at 19,156. The reclaim entry triggers on that close. Invalidation is a close back below 19,129, the sweep's own extreme; a return there says the level did not actually hold. The stop sits at 19,124, five points below the extreme, a 32 point risk from an entry near 19,156. The target is the recent range high near 19,240, an 84 point target, roughly 2.6 to 1. On a $10,000 account risking 1 percent, $100 divided by 32 points times $1 gives about 3 contracts.
Where this goes wrong
The setup fails when traders start calling every level touch a sweep and every reversal candle a reclaim, regardless of speed or context. A slow grind through a level with no volume burst, followed by a normal pullback, is not a sweep, it is just price moving, and forcing this framework onto it manufactures trades that were never really there. The discipline is reserving the label for the fast, obvious version and treating everything else as ordinary structure.
