Liquidity Grabs
The sweep-and-fail event Artemis Pro is built around: how grabs are tracked, and how a trigger pattern inside the grab window confirms a setup.
A liquidity grab is the moment Artemis Pro is built around: price sweeps a drawn level, takes the stops resting behind it, and closes back on the original side. This page explains the event, how the indicator tracks it, and exactly what it does and does not do about it.
The Event
Behind every marked swing high sit the stops of short sellers; behind every swing low, the stops of longs. When price pushes through such a level, those stops fire. If the push had real intent, price keeps going. But very often the move dies right there: the stops were the target, the fuel is now spent, and the traders who chased the break are trapped on the wrong side.
The chart fingerprint is unmistakable once you know it: a candle whose wick trades through the level while its body closes back on the original side. The wick is the grab. What follows is frequently a sharp move in the opposite direction, powered by the trapped traders exiting.
How Artemis Pro Tracks It
The grab logic runs on the Liquidity Lines module. When price touches a line (mitigation), Artemis Pro checks how the touch closed:
- Bullish grab (sweep of support): the candle trades below a support line but closes back above it.
- Bearish grab (sweep of resistance): the candle trades above a resistance line but closes back below it.
Either outcome records the grab and opens a short grab window. Clean breaks are timestamped too, and a candle that snaps back through a just-broken level within the next couple of bars also registers as a grab, because that is the same trap in slow motion. A grab is cancelled if price later closes back through the swept level in the breakout direction, since at that point the break was real after all.
What You See: Confirmed Setups And Label Prominence
The grab window changes two things on your chart.
The label grows. When a reversal pattern from the Signal Reference completes within 3 bars of a grab or level break, or on a bar that is itself a confirmed setup, its label prints large instead of small. A pattern firing in open space gets a tiny label; the same pattern firing right where liquidity was just taken gets a prominent one. Size is a read on the pattern happened, not a verdict that every condition of a trade is met.
