Quick answer
An inverse fair value gap is a Fair Value Gap that price has closed through, which flips its polarity. A bullish FVG that is violated by a body close becomes resistance; a violated bearish FVG becomes support. The first retest of the inverted range is the entry, with the stop just beyond the far edge of the gap and the target at the next opposing pool of liquidity.
What is an Inverse FVG?
A standard Fair Value Gap is a three-candle imbalance. When price respects the FVG on a retest, it defends the original direction. But when price closes through the far edge of the FVG, the imbalance is considered invalidated — and the level inverts.
- Bullish FVG closed through: the gap is now treated as bearish resistance. Retest = short opportunity.
- Bearish FVG closed through: the gap is now treated as bullish support. Retest = long opportunity.
FVG vs IFVG
| Fair Value Gap | Inverse FVG | |
|---|---|---|
| State | Fresh, unmitigated | Closed through by a candle body |
| Direction defended | The original impulse | The opposite direction |
| Entry | First retrace into the gap | First retest after inversion |
| Stop | Beyond the far edge of the gap | Beyond the far edge of the inverted gap |
| Bias needed | Bias agrees with the original gap | Bias has flipped |
| Invalidation | Body close through the gap | Body close back through the inverted range |
Why IFVGs work
The original imbalance represented unfilled institutional orders. When price closes through it, those orders have been absorbed and the dynamic has flipped — the side that was buying is now defending, and vice versa. The inverted level is where the new dominant side will defend again.
How to trade an IFVG
- Identify the original FVG and confirm price has closed (body, not wick) through the far edge.
- Mark the inverted level — the original FVG range becomes your retest zone.
- Wait for price to return to the IFVG. Best when it returns inside a Killzone.
- Enter on first touch (CE works) with stop just beyond the far side of the inverted gap.
- Target the next opposing liquidity pool.
Worked NQ example — bearish IFVG
- 09:32 ET — the opening drive higher leaves a bullish FVG on the 1-minute.
- 09:48 — price returns and a candle closes below the low of that gap. The bullish FVG is invalidated and inverts.
- 10:04 — price rallies back into the inverted range and stalls on the first touch.
- Short at the midpoint of the inverted gap, stop a few ticks above its high.
- Target the session low, then the previous day low — the structure prints around 1:3.
IFVG vs FVG — when to use which
- Use the FVG when daily bias agrees with the FVG direction and price retraces into it for the first time.
- Use the IFVG when daily bias has shifted, price has closed through the original FVG, and the retest aligns with the new bias.
Is an inverted fair value gap the same thing?
Yes — "inverted fair value gap", "inversion FVG" and "inverse FVG" all describe the same level: a gap that has been closed through and now defends the opposite direction. ICT material uses "inversion"; most charting communities shortened it to IFVG. There is no difference in the rules.
How a failed FVG flips, step by step
| Stage | What price does | What the level means |
|---|---|---|
| 1. Formation | Fast three-candle impulse leaves an untraded range | Fresh FVG — supports the impulse direction |
| 2. First retest | Price trades into the gap and holds | FVG working as intended |
| 3. Violation | A candle body closes fully through the far edge | The imbalance is spent — the FVG is dead |
| 4. Inversion | Price leaves the range in the opposite direction | The same range is now an IFVG |
| 5. Entry | Price returns to the inverted range and stalls | Trade the flip; stop beyond the far edge |
The signal that matters at stage 3 is the close. A wick beyond the gap is a liquidity sweep and leaves the original FVG intact. The cleanest inversions happen immediately after a market structure shift, when bias has genuinely turned, and are often confirmed by SMT divergence between NQ and ES at the same extreme.
Common mistakes
- Wick through, not close through. A wick is not an invalidation — it's a sweep. The FVG is still active.
- Trading IFVG against fresh bias. If bias hasn't actually shifted, the IFVG retest often fails.
- Stacking too many inversions. A gap that has flipped twice is noise; the cleanest IFVGs invert once, close to a swept high or low.
- No Killzone. Like any ICT setup, IFVGs are most reliable inside London Open or NY AM.

Frequently asked questions
What is an inverse fair value gap?
An inverse FVG, or IFVG, is a Fair Value Gap that has been closed through by price. Once invalidated, the level flips polarity — bullish FVGs become resistance and bearish FVGs become support on retest.
What is an inverted fair value gap?
The same thing as an inverse FVG. Inverted, inversion and inverse all describe a fair value gap that price closed through, so the range now defends the opposite direction.
IFVG vs FVG — what's the difference?
An FVG is a fresh imbalance that defends the original direction on retest. An IFVG is the same level after it has been closed through, where it defends the opposite direction.
How do I confirm an IFVG is valid?
Price must close (body, not wick) through the far edge of the original FVG. A wick through is a sweep, not an invalidation — in that case the FVG is still active.
Where do I place the stop on an inverse FVG trade?
Just beyond the far edge of the inverted gap — above its high for a short, below its low for a long. If price closes back through the inverted range, the setup is void.
What timeframe are inverse FVGs best on?
On NQ, the 1-minute and 5-minute inside a Killzone give the cleanest entries, with the 15-minute used to confirm that bias has genuinely flipped.
Do I need a market structure shift before trading an IFVG?
It is the strongest confirmation. An inversion that happens with a market structure shift means bias actually turned; an inversion without one is often just chop through an old gap.
How far can price travel from an IFVG entry?
Target the next opposing pool of liquidity — session high or low, then previous day high or low. On NQ these retests commonly resolve in the 1:2 to 1:3 range.
Can I trade IFVGs on NQ futures?
Yes — IFVGs are among the most common reversal setups in NQ Killzones. Bar-by-bar replay is the fastest way to build pattern recognition for them.

Data & methodology
All NQ and MNQ examples use Databento GLBX.MDP3 1-minute OHLCV candles for continuous front-month E-mini Nasdaq-100 futures, aggregated to higher timeframes (5m, 15m, 1h, 4h) so every bar agrees across timeframes. Sessions run 01:00–16:00 ET. ICT overlays are drawn algorithmically from the same price data used in the replay trainer.
