Inverse Fair Value Gap (IFVG): What the Flip Means

The term arrives sideways for most people. You already know what a fair value gap is: the unfilled area a fast move leaves between the first and third candle. Then someone says the gap "inverted", and you start looking for a second object on the chart. There isn't one. The gap you already marked is the gap in question; what changed is what you expect from it.

This page is about that change: what has to happen before a gap counts as inverted, how that differs from a gap being filled, and what the markup actually shows when it happens. If the underlying object is still fuzzy, start with what a fair value gap is and come back.

What is an inverse fair value gap?

An inverse fair value gap, or IFVG, is a fair value gap (FVG: the unfilled imbalance left between candle one and candle three of a fast move) that price has closed through. Before that close, the zone is a place where price might be defended. After it, the same prices are watched from the opposite direction.

The word does a lot of work in trading videos and very little of it is definitional, so let me be blunt about what is being claimed. Nothing about the geometry changes: the high of candle one and the low of candle three still bound the same rectangle, and the prices are identical. What changes is which side of that rectangle you expect price to struggle with.

"Inverse" describes the role, not a new pattern

There is no separate three-candle formation called an inverse fair value gap. There is one gap, and it has a history: it formed, it held or it did not, and after it failed traders keep watching it because failed levels tend to stay interesting. If you have traded support that broke and then capped the next rally, you already know the mechanic under a different name. The SMC vocabulary just applies it to an imbalance instead of a horizontal line.

How does a fair value gap invert?

Inversion happens in two moves, not one. First a candle body closes past the far edge of the gap, which ends the gap's life as a zone on that side. Then price comes back to those prices from the new direction and gets rejected there. The first move is the criterion; the second is the part you can actually act on.

Take a bullish gap: a strong up-candle leaves the low of candle three above the high of candle one, and the unfilled area between them sits below price. While that area holds, it is a zone buyers have some reason to defend. Price can dip into it, wick through part of it, even trade most of the way across it, and the reading stays the same. Price is mitigating the gap, which is ordinary behaviour.

The reading changes when a candle closes below the low edge of that zone. At that point the imbalance has been traded through with intent rather than tested, and I stop treating that area as support: there is nothing left for buyers to defend. If price then rallies back into the same prices, it is arriving from underneath, into an area that just failed to hold. That is the setup the word "inverse" points at.

Bearish gaps work the same way mirrored. A bearish gap sits above price as an area sellers might defend; a body closing above its high edge ends that, and a later return from above is read against the old zone.

Filled, partly filled, or inverted: which one is it?

These three get used interchangeably and they are not the same event. A partly filled gap still works as a zone. A fully filled one is simply done, with nothing flipped. What keeps an inverted gap on the chart is that it failed. The difference between the three is entirely about where the candle closed.

Traders often say a gap got "disrespected" when price walks through it without reacting. That is the same event in slang, and the slang is worth knowing because it tells you what to do next: stop waiting for that area to hold, and start watching how price behaves when it comes back to it.

There is a second vocabulary for the same event, and both are useful side by side. "Inverse fair value gap" is ICT and Smart Money Concepts terminology; in structural markup the same imbalance simply carries one of three states: active, closed, or absent. A body trading into the imbalance already marks it closed, and a closed imbalance no longer qualifies an order block that leans on it. Inversion is the stronger version of the same failure: the body does not stop inside the zone, it finishes past the far edge, and that changes which side traders watch the area from. Neither vocabulary replaces the other; they name one failure from two angles.

What does an inverse fair value gap look like in structural markup?

This is where expectations and charts part company. Nothing appears on the chart labelled IFVG. Three separate things happen instead: the old gap stops counting as active, an opposite-side order block tends to print over the same prices, and the character of the structure around it often breaks. Reading the inversion means reading all three together, not hunting for one object with a name on it.

First, something drops out. The old gap stops being an active imbalance the moment a body overlaps it, so on a markup that tracks state it simply stops counting. It does not turn a different colour or acquire a new label.

Next, an opposite-side order block tends to appear over the same prices. That is not a coincidence dressed up as insight: the candle that closes through a zone is often the same kind of candle a block is drawn from, and when it leaves a fresh imbalance of its own, the block lands where the old zone was. The area stays interesting because something new is marked there, not because the old rectangle was renamed.

Context is the third piece. A move that breaks a gap against the gap's own bias often prints a change of character (CHoCH) in the structure around it too, and that is the part people skip when they go hunting for a single "IFVG signal" instead. For how a gap gets traded while it is still working, the fair value gap workflow covers the entry side in detail.

What the inversion does not tell you

It tells you a zone failed. It does not tell you the opposite side will hold, and it does not tell you to enter anything. An inverted gap is context: a piece of information about what price has already refused to do. Treating it as a trigger is how a useful observation turns into a bad entry.

The honest limits belong here too. Plenty of gaps get broken and then never revisited, so there is nothing to act on. Plenty of others get revisited and sail straight through, because a zone that failed once has no obligation to work in reverse. And the first return is not automatically the one that matters. Price can pass through the old area several times while structure sorts itself out.

What the inversion is good for is removing an idea from your chart. The moment a body closes through a gap, the trade you were waiting for at that zone is gone, and holding on to it costs more than missing it would have. Everything after that is a new read.

Watching a gap change status without redrawing it

The concept is not the hard part here. Gaps accumulate, most of them quietly die, and keeping track of which ones are still active normally means redrawing rectangles across several pairs by hand. That is the actual grind. Watching status without redrawing means letting the chart hold the state of each gap for you, so the flip shows up on the same prices instead of in your notes.

SMC ToolBox detects fair value gaps as points of interest alongside order flow, SCOB, equal highs and lows and the rest of the set, with the edges finalised on bar close so a zone marked yesterday still sits where it sat. Money Hunter marks the change of character over the same area, which is the third of the three things above. Neither draws an object called an inverse fair value gap, and neither decides the trade for you. They keep the state visible so the read is yours to make.
