Liquidity Void — How It Differs From an FVG and How It Gets Filled

Some moves leave the chart looking like a vacuum cleaner went through it: a few giant candles in one direction, zero pullbacks, zero overlapping wicks. BTC can cover several thousand dollars this way in a couple of hours. What's left behind after such a move is what ICT calls a liquidity void — a vacuum of liquidity. It's a zone where trades happened "on the run", without a fair exchange between buyers and sellers — and that's exactly why the market has a habit of coming back to it. In this article we break down how a void differs from an ordinary FVG, when (and whether at all) it gets filled, and how to use price's return into the vacuum as a setup.

What a liquidity void is

The name says it all: "liquidity" is the presence of willing buyers and sellers, "void" is emptiness. A liquidity void forms when price moves in one direction so violently that the other side of the trade was missing along the way. The typical scenario: the market breaks out of consolidation with a displacement move — a series of large, directional candles — because on one side there simply were no orders that could slow the move down. Price didn't "conquer" that zone; it flew through it.

On the chart, you'll recognize a void by three traits:

• A series of consecutive directional candles with large bodies and no internal pullbacks;
• No overlapping wicks — the wick of each next candle doesn't enter the previous candle's range, so no two-sided trading took place in the zone;
• A starting point in consolidation — the vacuum usually begins where price left an accumulation/distribution range.

A void can be bullish (a dynamic breakout upward — supply was missing) or bearish (a slide down — demand was missing). In both cases the zone is "unfinished business": the prices inside the vacuum were never fairly traded, so the price-delivery algorithm treats it as a place for later repricing — a return and a fill, in whole or in part.

Liquidity void vs FVG — the container and the bricks

The most common question: how is this different from a Fair Value Gap? The answer is simple once you look at the scale:

• An FVG is a pattern of exactly three candles — the gap between the wick of the first and the wick of the third. The smallest unit of inefficiency you can point to on a chart.
• A liquidity void is the entire displacement zone — it might span three candles, but just as easily five or eight. A single void often contains two or more FVGs inside it.

The best analogy: the void is a container, and FVGs are the bricks it's built from. The distinction isn't academic — it has direct trading consequences. Whoever treats an eight-candle void like a single gap places their stop "beyond the FVG", i.e. in the middle of the vacuum — exactly where price has every right to still reach. A void is traded off the levels of the whole zone: its edges and its midpoint, not the borders of a single brick.

The most important level inside the vacuum is consequent encroachment (CE) — the middle of the zone, 50% of its height. Statistically it's the void's most reactive spot: price very often returns precisely to the midpoint of the vacuum, reacts, and drives off without filling the rest. We dedicate a separate article to the CE level.

Does the market always fill the vacuum?

Three honest answers to three versions of this question:

Will it fill immediately? There's no time rule. Sometimes price returns into the void within the same session; sometimes after several days. You can't "summon" the fill — you can only wait for it with a ready plan.

Will it fill for certain? No. The market can create another void and drive away, leaving the previous one untouched for weeks. The further price moves structurally away from the vacuum, the smaller the chance of a return — fresh voids (from the same session, the same week) have the highest priority.

Will it fill completely? Often not. A return to CE — the middle of the zone — and a bounce is a more common scenario than a full close. That's why waiting "until it fills entirely" lets most opportunities slip away, and the minimum condition for a setup is precisely a repricing to 50%.

How to identify a liquidity void step by step

1. Establish the HTF structure. On D1/H4, determine whether the market is bullish or bearish. That decides which voids interest you at all (those aligned with the trend) and which price will ignore.
2. Find displacement out of consolidation. Look for a series of large directional candles breaking out of a clear range — on crypto, classically after a weekend sideways range or around major macro data.
3. Check the wicks. If the wicks of consecutive candles don't overlap the previous candles' ranges — you have a vacuum. Overlapping wicks mean two-sided trading did take place after all.
4. Mark the whole zone. From the level where the move launched to the point where the first pullback appeared. That is the void — not a single gap in its middle.
5. Mark CE and the internal gaps. The 50% line of the entire zone plus the individual FVGs inside. These are your reaction levels for price's return.
6. Assess age and location. A fresh void in the direction of the trend, below/above the current price — you watch it. An old one, structurally bypassed — you delete it from the chart.

The edges of the vacuum are usually defined by significant highs and lows, which our SRL indicator marks automatically — you can see at a glance where the displacement launched from and where price would have to return for a full repricing.

How to use a liquidity void in trading

A void is traded "off the return" — not as it forms, but when price comes back into the vacuum. The HTF→LTF scheme:

Step 1 — the trend-alignment filter. This is the overriding condition: a bullish void within a bullish D1/H4 structure acts like strong support; a bearish void in a falling one — like resistance. A void against the trend (e.g. a bearish vacuum inside a bull-market correction) most often gets run straight through — price fills it and carries on its way.

Step 2 — wait for the return into the zone. Price has to pull back into the vacuum area, ideally reaching the CE level. The return itself isn't a signal yet — it's merely arriving on location.

Step 3 — trigger on the LTF. On M5–M15 you wait for a structure shift (MSS) in the direction of the original displacement — proof that the vacuum is actually working as a reaction zone, not as a tunnel. The same confirmation logic you apply after a liquidity sweep.

Step 4 — entry, stop, target. Entry on the retest of the zone after the MSS, ideally around CE. Stop conservatively beyond the void's opposite edge; tighter — beyond the extreme of the displacement candle. Target: the liquidity pool the original move was gunning for — the opposite side of the consolidation, an old high/low, equal highs/lows.

The setup's logic is deeply consistent with the rest of the liquidity framework: the displacement happened because the market was racing toward a specific pool; the return into the void is refueling before finishing that journey. You board at the station, not while the train is moving.

Most common mistakes

• Trading every void. A vacuum against the HTF trend isn't a reaction zone — it's a corridor. The D1/H4 alignment filter is the first thing you check, not the last.
• Expecting a full fill. Many voids close only to CE and drive off. Whoever waits for the full repricing watches most moves from the platform.
• Treating a void like a single FVG. Different scale, different levels, different place for the stop. Confusing the container with the brick ends with a stop in the middle of a zone price has every right to reach for.
• Entering on the return without confirmation. Touching CE is the "where". An MSS on the lower timeframe is the "when". Without the trigger, a void can get filled straight through in one move.
• A stop on the CE line. The vacuum's most reactive level is also the one most often tested a second time. You tuck the stop beyond the zone's edge, not in its middle.
• Trading stale vacuums. A void that structure has long since passed by loses its magnet status. Priority goes to zones from the current session and the current week.

The liquidity void completes the picture of liquidity mechanics: pools and sweeps describe where the market hunts orders, and the vacuum — what's left on the chart when the hunt ran out of a counterparty. Both are tracks of the same animal. Learn to read them together: displacement tells you where the market wanted to go, and the void — where it will return to regroup before finishing that journey.
