FVG vs IFVG: The Difference on the NQ Chart

An FVG is a gap price may respect. An IFVG is the same gap after price closes through it and the role flips. The rule, the edge cases, and a 5-minute NQ example.

By Hunter (Orion). October 10, 2026. 7 min read.

Short answer: An FVG (fair value gap) is a three-candle imbalance that price may come back to and respect. An IFVG (inverse or inversion fair value gap) is that same zone after a candle body closes through it. The role flips. A failed bullish FVG becomes resistance, and a failed bearish FVG becomes support.

That is the whole difference. Same box on the chart, opposite job. The rest of this post is about marking both correctly on NQ, because most of the confusion comes from sloppy marking, not from the concept.

What an FVG is

An FVG is a gap between candle 1 and candle 3 of a three-candle move. Candle 2 is the big displacement candle that leaves the gap behind.

Bullish FVG: candle 1's high is below candle 3's low. The zone runs from candle 1's high up to candle 3's low.
Bearish FVG: candle 1's low is above candle 3's high. The zone runs from candle 3's high up to candle 1's low.

Price moved through that area so fast that it barely traded there. When price comes back, traders watch the zone for a reaction. A bullish FVG is read as possible support. A bearish FVG is read as possible resistance.

The midpoint of the gap has its own name. It is called consequent encroachment, or CE. A lot of traders watch whether price respects the CE or closes past it.

What an IFVG is

An IFVG is an FVG that failed. Price came back, did not respect the zone, and closed through it with a candle body.

Once that happens, the zone does not disappear. It changes sides.

A bullish FVG that gets closed through to the downside becomes a bearish IFVG. Old support, new resistance.
A bearish FVG that gets closed through to the upside becomes a bullish IFVG. Old resistance, new support.

My favorite thing about IFVGs is what they tell you about the move. The zone that should have held did not. Whatever side was defending it got run over. That shift is the information.

FVG vs IFVG side by side

	FVG	IFVG
What it is	Three-candle imbalance	An FVG that price closed through
Bullish version acts as	Possible support	Possible support, from a failed bearish FVG
Bearish version acts as	Possible resistance	Possible resistance, from a failed bullish FVG
Created by	Displacement leaving a gap	A body close beyond the far edge of an FVG
Invalidated by	A body close through it, which makes it an IFVG	A body close back through it the other way
Where it shows up	After any fast move	After a reversal or a strong push through a zone

The rule that confirms an inversion: body close, not a wick

This is where most people mess it up. A wick through an FVG is not an inversion.

NQ wicks through levels all day. A spike through a gap that closes back inside the zone just means the gap got tested. It did not fail. For an inversion, I want a candle body to close beyond the far edge of the gap.

For a bullish FVG to invert, a body has to close below the bottom of the zone, which is candle 1's high.
For a bearish FVG to invert, a body has to close above the top of the zone, which is candle 1's low.

Use the same timeframe the gap formed on. A 5-minute FVG needs a 5-minute close through it. A 1-minute candle closing past a 5-minute gap is early information, not confirmation.

How long an IFVG stays useful

An IFVG is not a level you keep forever. A few things wear it out.

A body close back through it. If a bullish IFVG gets closed below, it failed too. I stop treating it as anything.
Multiple retests. Each touch eats into whatever was resting there. The first retest is the one most traders care about.
The session changing. A 5-minute IFVG from the overnight session can mean a lot less once New York opens and volume shows up.
Higher timeframe context. A 5-minute bullish IFVG sitting right under a 1-hour bearish FVG is boxed in. I give the bigger zone more weight.

Example on the 5-minute NQ chart

This walk-through is illustrative. The prices are hypothetical and round so the math is easy to follow. It is a read of how the zones work, not a trade anyone took.

The gap forms. Just after the 9:30 ET open, NQ drops hard. Candle 1 (9:35) has a low of 31,152.00. Candle 2 is a long red candle. Candle 3 (9:45) has a high of 31,138.50. That leaves a bearish FVG from 31,138.50 to 31,152.00. That is 13.5 points tall, with the CE at 31,145.25.
Price respects it at first. NQ chops lower to around 31,110.00. A bounce at 10:00 wicks up to 31,149.00 and closes back at 31,136.00, below the zone. That wick tagged the gap but did not close through it. Still a bearish FVG.
The inversion. At 10:15, a 5-minute candle closes at 31,158.75. That body closed above 31,152.00, the top of the zone. The bearish FVG is now a bullish IFVG from 31,138.50 to 31,152.00.
The retest. At 10:40, price pulls back into the zone and trades down to 31,144.00, just past the CE. The 5-minute candle closes at 31,150.25, back inside the zone and above the CE.
What I would watch. The zone held on its first retest. If a 5-minute body later closes below 31,138.50, the IFVG failed and I stop treating it as support. If it keeps holding, the next obvious reference is the nearest prior high above.

Notice what changed between step 2 and step 3. Same 13.5-point box. At 10:00 it was resistance. By 10:15 it was support. Nothing about the box moved. A body close changed its job.

Common mistakes

Calling a wick an inversion. Wait for the body to close past the far edge.
Mixing timeframes. Confirm a 5-minute gap with a 5-minute close.
Marking every tiny gap. On NQ, a 2-point gap on the 1-minute is noise. Gaps that come from real displacement matter more.
Ignoring the session. Overnight gaps and New York gaps do not carry the same weight.
Treating the zone as a line. It is a zone. Price can trade into it, past the CE, and still hold.
Holding on to a dead IFVG. Once it gets closed back through, it is done.

FAQ

Is an IFVG stronger than an FVG?

Not by default. They answer different questions. An FVG asks whether price will respect a gap. An IFVG shows you a gap that already failed and flipped sides. Which one matters more depends on where it sits and what the higher timeframe is doing.

Does a wick through an FVG make it an IFVG?

No. A wick that closes back inside the zone is a test. You need a candle body to close beyond the far edge of the gap, on the same timeframe the gap formed on.

What timeframe works best for IFVGs on NQ?

A lot of NQ day traders work the 5-minute for zones and use the 15-minute or 1-hour for direction. The 1-minute prints so many gaps that it gets noisy fast.

Can an IFVG fail?

Yes. If a candle body closes back through it in the other direction, it failed. Treat it as invalid and move on.

Where Zero-G fits

These zones are a read of the chart. You still choose the entry, the exit, and the risk.
