Inverse Fair Value Gap Explained: What an IFVG Is and How to Trade It

What Is an Inverse Fair Value Gap?

A fair value gap is a three candle imbalance. The wick of the first candle and the wick of the third candle do not overlap, which leaves a range that price moved through in one direction without meaningful two-sided trade. That untraded range is the gap.

An inverse fair value gap is what that same zone becomes once price closes through it instead of respecting it. A bullish fair value gap that should have held as support, but which price closed below, becomes resistance on the way back up. A bearish gap that price closed above becomes support.

Nothing new is drawn on the chart. The level is the same range it always was. What changes is the side of it that price is now expected to defend, which is why the pattern is described as an inversion rather than a separate formation.

Inverse, Inverted, or Inversion: The Same Concept

This concept is one of the few in ICT and Smart Money literature that is discussed under three interchangeable names, which makes it harder to research than it should be.

→ Inverse fair value gap is the most widely used phrasing and the one most traders search for.

→ Inverted fair value gap appears frequently in community material and describes the same flip.

→ Inversion fair value gap, often shortened to inversion FVG, is common in ICT-derived teaching and is the naming Toodegrees uses for its own tool.

IFVG is the standard abbreviation for all three. If you have read two explanations that seemed to contradict each other, the disagreement is almost always vocabulary rather than method.

How a Fair Value Gap Becomes an Inverse FVG

The sequence is mechanical, which is what makes it possible to define consistently.

→ A fair value gap forms as a three candle imbalance.

→ Price trades back into that gap at some later point.

→ Instead of reacting away from it, price closes a candle body fully through the far side of the range.

→ The zone is now inverted. It is carried forward as an opposing reference rather than a supporting one.

The body close is the part that traders most often get wrong. A wick that spikes through the gap and closes back inside has not inverted anything. It has tested the gap and rejected it, which is the original fair value gap behaving exactly as expected. Treating that wick as an inversion produces levels that were never valid.

Inverse Fair Value Gap vs Fair Value Gap

The two are the same price range read at two different stages of its life, which is why comparing them as separate patterns causes confusion.

A fair value gap is an area of unfilled imbalance that price may return to and respect. It is an area of potential support or resistance that has not yet been tested.

An inverse fair value gap is that same area after it has failed. It has been tested, it did not hold, and price is now on the other side of it. The expectation reverses accordingly.

This matters for risk placement more than for entries. A trader treating a broken gap as though it were still valid support is defending a level the market has already resolved.

Why the Flip Happens

The structural explanation is order placement, not sentiment.

Traders who positioned inside a fair value gap expecting it to hold are offside the moment price closes through it. Their protective stops sit on the other side of that range. Traders who missed the original move often place resting orders around the same area.

When price returns to a zone that has already failed, it is returning to a band that holds both trapped positions and unfilled interest. That concentration is the reason the level frequently produces a reaction on the retest.

This is context, not a forecast. An inverted gap describes where reactive orders are likely to sit. It does not tell you that price will turn there.

Reading an IFVG in Context

An inverse fair value gap in isolation is a line on a chart. Most of its usefulness comes from what surrounds it.

→ Higher timeframe bias. An IFVG that opposes the dominant higher timeframe direction is a weaker reference than one that agrees with it.

→ Preceding liquidity. Inversions that occur after an obvious sweep of highs or lows tend to sit inside a clearer narrative than inversions that appear mid range.

→ Timeframe of origin. A gap inverted on the 4H carries different weight from one inverted on the 1m. Both are valid. They answer different questions.

→ Session. An inversion during a major session carries more participation behind it than one formed in thin hours.

The goal is not to collect more levels. It is to reduce the chart to the few that agree with everything else you have already established.

Common Mistakes with Inverse Fair Value Gaps

→ Counting wick penetrations as inversions. Without a body close through the range, the original gap is still the active level.

→ Marking every gap on the chart. Most imbalances are never revisited. A chart covered in boxes hides the two or three that matter.

→ Using an IFVG as a standalone trigger. It defines a level of interest. It does not define direction, timing, or risk on its own.

→ Mixing timeframes without labelling them. An inversion from a 15m chart and one from a daily chart are not interchangeable references, and treating them as equal is where most inconsistency comes from.

→ Redrawing after the fact. If a level is adjusted once price has already reacted, it is no longer being tested. It is being fitted.

Automating the Identification

The rules above are simple to state and tedious to apply. Every session produces new imbalances, each has to be tracked for a body close through it, and inverted zones have to be carried forward while stale ones are cleared.

Doing this by hand is where consistency usually breaks down, not because the concept is difficult, but because manual marking drifts. Levels get missed on busy days and get drawn generously on quiet ones.

The Inversion Fair Value Gap° tool applies the same definition on every candle: it tracks fair value gaps, marks the ones price has closed through, and carries the inverted zones forward without the chart being rebuilt each morning. The judgement of whether a level fits the wider picture stays with the trader. What is automated is the bookkeeping.

Imbalance and gap behaviour is studied well beyond retail trading, in market microstructure research on order flow, price discovery and the way untraded ranges are revisited. The inverse fair value gap is a specific, rule-based case of that broader idea: a zone that failed once is carried forward as an opposing reference rather than discarded.
