Inverse Fair Value Gap (IFVG): When an FVG Flips Its Role

A fair value gap is expected to act as support or resistance. Sometimes it does not. Price runs straight through it and closes on the other side. In the ICT framework, that failure is not just discarded. The broken gap becomes an inverse fair value gap (IFVG), and traders watch it to act in the opposite role.

This lesson covers how to recognize the flip, how traders build an entry around it, and where the idea stops being valid.

What it is

An inverse fair value gap is a former FVG that price has closed through with a candle body. After that close, the zone is expected to work the other way:

• A bearish FVG that price closes above can become a bullish IFVG, acting as possible support.
• A bullish FVG that price closes below can become a bearish IFVG, acting as possible resistance.

The reasoning is similar to the familiar idea that broken resistance can become support. Sellers who defended the bearish gap were overwhelmed, and traders now treat the same price area as one where buyers have shown control.

Not every educator uses the term the same way, and some traders are skeptical of trading failed patterns at all. Treat it as one tool among several.

How to identify it

1. Start with a valid FVG. Mark the original gap using candle 1 and candle 3 wicks.
2. Look for a body close through it. A wick into or through the gap is not enough. A candle must close beyond the far edge.
3. Check the context. The strongest examples usually follow a liquidity sweep and come with a market structure shift.
4. Redraw the zone in its new role. The same price boundaries apply, now read in the opposite direction.
5. Wait for the retest. The entry idea forms when price comes back to the zone from the other side.
6. Set invalidation. A body close back through the zone in the original direction ends the idea.

Worked example: a bullish IFVG on GBP/USD

The following prices are illustrative. Assume GBP/USD is falling on the 5-minute chart during the London session.

Step 1: the bearish FVG. During the decline, three candles leave a bearish gap:

• Candle 1 low: 1.2650
• Candle 3 high: 1.2638

The gap runs from 1.2650 down to 1.2638, a 12-pip zone, with consequent encroachment at 1.2644.

Step 2: the sweep. Price continues lower, runs below an obvious prior low at 1.2610 and trades to 1.2604, taking out sell-side liquidity.

Step 3: the shift. Price displaces higher. A candle closes at 1.2662, above both the top of the old gap (1.2650) and a minor swing high at 1.2656. The bearish FVG has failed and is now treated as a bullish IFVG from 1.2638 to 1.2650.

Step 4: the retest plan.

Risk: 1.2648 − 1.2630 = 18 pips. Reward: 1.2700 − 1.2648 = 52 pips. The ratio is about 1:2.9.

Risking 1% of a $5,000 account ($50) with about $10 per pip per standard lot: $50 ÷ (18 × $10) ≈ 0.28 lots. Check your own numbers with the Position Size Calculator.

Invalidation: a 5-minute body close below 1.2638 means the zone failed again as support. The stop at 1.2630 sits just below that level to allow for normal noise.

How traders use it

• As an entry after an MSS. The IFVG is often the first zone price returns to after a reversal, which makes it a natural place to look for a retracement entry.
• As confirmation. When an opposing gap fails decisively, some traders read it as evidence that order flow has changed direction.
• Alongside other arrays. An IFVG that overlaps a breaker block or sits in discount for a long is usually given more weight.
• For trade management. If price closes back through the IFVG, many traders exit rather than wait for the full stop.

As with every setup, losses are a normal part of trading. Define your stop and size before entering.

Common mistakes

• Counting wicks as failures. A wick through a gap often marks a sweep, not an inversion. Wait for a body close.
• Trading every inversion. In choppy markets, gaps get closed through constantly. Without a sweep and shift, the signal is weak.
• Forgetting the original direction of the gap. Mark the gap clearly so you do not mix up the old and new roles.
• Entering before the retest. Chasing the breakout candle usually means a wider stop and worse risk-to-reward.
• No invalidation level. If the zone fails again, the reason for the trade is gone.

Summary

An inverse fair value gap is an FVG that price closes through, after which the zone is expected to act in the opposite role. A failed bearish gap can become support and a failed bullish gap can become resistance. Traders favor IFVGs that follow a liquidity sweep and market structure shift, enter on the retest, and treat a body close back through the zone as invalidation. Similar role-reversal logic applies to order blocks, as the lesson on breaker and mitigation blocks explains.
