ICT Liquidity Void Explained: Price Gaps and Trading Risks
Understand how traders describe low-overlap price movement, why the area may be revisited or crossed, and how to test a void hypothesis without assuming a guaranteed fill.

The ICT Liquidity Void is one of the most misunderstood concepts in the ICT framework because it appears to behave like support or resistance but is actually the opposite. A Liquidity Void is a price range where almost no trading activity occurred — either because price moved through it so rapidly that neither buyers nor sellers could participate meaningfully, or because it represents a gap zone where the market simply was not open. The void is empty. When price enters it, there is nothing to stop it — it passes through rapidly toward the next area of actual liquidity.
What Creates a Liquidity Void?
Liquidity Voids are created by rapid, one-sided displacement moves. When the algorithm delivers price aggressively from Point A to Point B in a short period, it leaves behind a price range where almost no transactions occurred. Both buyers and sellers were unable to participate at those price levels because the move was too fast. The result is a void — a zone of near-zero volume and near-zero liquidity.
Common examples: a large gap opening on Monday morning (the gap between Friday's close and Sunday's open is a literal void — the market was closed), a major news event that moves price 50 pips instantly (all those intermediate price levels were voided), or an aggressive Asian session spike that moves price rapidly before any retail participation could occur.
How Price Behaves in a Liquidity Void
When price enters a Liquidity Void, it has no reason to slow down. There are no significant orders, no PD Arrays, and no institutional interest in the void zone — because none were placed there when the zone was created. Price moves through it at approximately the same speed it takes to enter. This is why retail traders who place support/resistance levels in voids are consistently surprised when those levels offer no reaction.
The void continues until price reaches the next area of actual liquidity — a genuine PD Array, an old swing high or low that accumulated orders, or an area where significant trading activity previously occurred. That is where price will slow down and potentially react.
Using Liquidity Voids for Trade Targeting
- When your trade enters a Liquidity Void, expect price to accelerate — do not take early profits within the void zone as the absence of resistance means the move will continue.
- Identify the first area of actual liquidity beyond the void — this is your minimum target. The void will be filled rapidly once price enters it.
- When setting stop losses, avoid placing them within a void zone below your entry. A stop in a void will be hit by the rapid price movement through the void even if the overall direction is correct.
- Mark voids on your chart with a different color or shading to distinguish them from standard price ranges. Any price level within a marked void is not valid support or resistance.
- Opening gaps (NWOG and NDOG) are specific types of liquidity voids — they may be revisited, but could also remain unfilled.
The most practical application of liquidity voids: when you have identified a trade entry at a PD Array and your target is on the other side of a void zone, increase your take-profit target to account for the rapid move through the void. A 20-pip PD Array entry with a 30-pip void between the entry and the next liquidity area means your realistic minimum target is 30 pips (the void fill) + whatever distance to the next PD Array beyond it — not 20 pips.
Worked hypothetical example
Three consecutive candles move quickly from 100 to 104 with little overlap, so a trader marks the intervening area as a candidate void under a written definition. On a later pullback, price pauses near 102 and then turns before reaching the other edge. The observation is logged as a partial revisit, not a failed market or a guaranteed future fill.
Failure case and what to test
A void identified from candle shapes does not measure all actual trading activity. Results depend on timeframe, data feed and the definition of overlap, and a fast move can continue or reverse without returning to the marked area.
Test checklist
- Define the candle sequence and minimum overlap rule in advance.
- Track full fills, partial revisits and no revisits separately.
- Test whether the reference adds value beyond ordinary momentum and support/resistance.
