IFVG vs FVG

The difference in IFVG vs FVG is one event: whether price broke through the gap or respected it. A fair value gap is an unfilled three-bar imbalance that often acts as support or resistance. An inverse fair value gap is that same zone after price has closed through it, which flips its role entirely. This guide covers how each one forms, how to tell them apart on a live chart, and why the inversion is the more reliable of the two.

What a fair value gap is

A fair value gap forms across three consecutive candles. Take the high of the first candle and the low of the third. If the third candle’s low sits above the first candle’s high, the space between them was never traded through, and that space is the gap.

The mechanism is simple. Price moved so quickly in one direction that orders on the other side never filled. Traders reading this style of chart treat the untraded zone as unfinished business, and expect price to return to it later.

The bearish version is the mirror. The third candle’s high sits below the first candle’s low, leaving an untraded band above the current price. Our guide to the inverse FVG covers the concept in more depth.

How a fair value gap behaves

A bullish gap should act as support. Price rallies away, later retraces into the zone, finds buyers, and continues up. That retracement is the trade most people are waiting for.

Traders say the gap fills when price trades back through the whole zone. Partial fills are common and normal. Many traders watch the midpoint, since price frequently reacts there rather than at the far edge.

What matters for this comparison is the outcome. If the zone holds and price turns, it did its job as a fair value gap. If price closes clean through it, the zone has failed, and that failure is where the inverse version begins.

IFVG vs FVG: the moment they diverge

An inverse fair value gap is a fair value gap that failed. Price returned to the zone, did not respect it, and closed through the far side. The zone is still on your chart, but its meaning has flipped.

A bullish gap that price closes below stops being support and becomes resistance. A bearish gap that price closes above stops being resistance and becomes support. The level is identical; only the expected reaction changed.

The logic behind it is straightforward. Traders positioned at the gap expected it to hold. When it broke, those positions were wrong and many are now trapped. A retest of the zone from the other side gives them a chance to exit near breakeven, and that selling or buying pressure is what makes the level react a second time.

Why the inversion tends to be stronger

A fresh gap is a hypothesis. It marks a place price might react, and plenty of gaps never matter at all. You are trading on the expectation that other participants care about the same zone.

An inversion carries evidence. Price already visited the zone and rejected the original reading, which tells you something overwhelmed the pressure that created the gap. You are no longer guessing whether the level matters, because the market has already reacted to it twice.

That is why many traders skip fresh gaps entirely on lower timeframes and wait for an inversion. Fewer setups, better ones. The same principle drives our liquidity sweep and breaker block guides, both of which trade a level after it has failed rather than before.

Reading them on a live chart

Work top down. Mark gaps on H4 or the daily first, because those zones attract far more attention than a three-bar imbalance on M5. Then drop to H1 or M15 for the entry.

Three checks separate a usable zone from noise. First, size: the gap should be a meaningful fraction of the recent range, not two pips of drift. Second, the impulse: a gap left by a strong directional move carries more weight than one inside a range. Third, location: a gap sitting at a prior high, low or session boundary matters more than one in the middle of nowhere.

For the inversion specifically, wait for the close. A wick through the zone is not an inversion. Price must close beyond the far edge on the timeframe you are trading, otherwise you are calling a break that has not happened.

Trading each one

On a fresh bullish gap, the entry is a limit order inside the zone or a reaction candle at its edge. The stop goes below the gap, since a close under it invalidates the idea entirely. Targets usually sit at the prior swing high or the next zone above.

On a bullish inversion, you are now short. Wait for price to close below the gap, then look for a retest from underneath. Enter on rejection, stop above the zone, target the next level down. Our ATR stop loss guide gives a volatility-based alternative to a fixed placement, and the position sizing calculator converts that distance into lots.

One rule saves a lot of money here: do not flip your bias mid-trade. If you are long a gap and it breaks, the trade is over. Taking the inversion short is a new trade with its own entry, stop and confirmation, not a continuation of the old one.

Common mistakes

Four repeat. Calling an inversion on a wick rather than a close tops the list, and it produces trades against a level that never actually broke. Marking every three-bar gap comes second, which buries the chart in zones that mean nothing. Third, traders use M1 and M5 gaps with no higher timeframe context. Fourth, they treat a filled gap as a failed one, when a normal fill and a close through are different events with opposite meanings.

Where to go next

Both concepts sit inside a wider structural method. Start with our ICT trading strategy guide for the framework, then read market liquidity for why these zones attract price at all. The liquidity trap guide covers the trapped-trader dynamic that powers the inversion.

FAQ

What is the difference between IFVG and FVG?

A fair value gap is an untraded three-bar imbalance expected to act as support or resistance. An inverse fair value gap is that same zone after price has closed through it, which reverses the role it plays.

How do I confirm an inverse fair value gap?

Wait for a candle to close beyond the far edge of the original gap on your trading timeframe. A wick through the zone is not enough, since price often pierces a level and recovers within the same bar.

Is an inverse fair value gap more reliable?

Many traders find it so, because the zone already survived a test and then broke, rather than merely sitting on the chart. You are reacting to something the market did instead of predicting that a fresh zone will matter.

Which timeframe suits these zones?

Mark them on H4 or the daily, then execute on H1 or M15. Gaps on M1 and M5 form constantly and most carry no significance without higher timeframe context behind them.

Does a filled gap become an inverse gap?

No. Filling means price traded back through the zone, which is normal behaviour. Inversion needs a close beyond the far side, so the market proves the original reading wrong rather than simply satisfying it.

Can I trade only inverse fair value gaps?

Some traders do, accepting fewer setups for better evidence. It still needs structure, a level and risk control around it. Trading involves risk, results are not guaranteed, and past performance is not indicative of future results.
