- The one-line difference: A fair value gap is an unfilled imbalance that still points in its original direction. An inverse fair value gap is that same gap after price has closed through it, flipping its role to the opposite side.
- The rule that matters: Inversion requires a body close beyond the gap, not a wick through it. A wick through and back leaves the original FVG intact.
- Which to trade: The FVG when price is still delivering in its direction. The IFVG after a reversal, because the inversion is itself evidence the delivery state changed.
These two terms get used as if they were alternatives. They are not. An inverse fair value gap is not a different kind of gap — it is the same gap at a later point in its life, after something specific happened to it.
Understanding the transition is what makes both usable, because the event that converts one into the other is also one of the cleanest reversal signals the framework offers.
What each one is
A fair value gap is a three-candle structure where candle one's extreme and candle three's extreme do not overlap, leaving a band of prices that were skipped. A bullish FVG sits below price and is expected to act as support when price returns. A bearish FVG sits above and acts as resistance.
An inverse fair value gap is what that same zone becomes once price closes decisively through it. The bullish gap that failed to hold becomes resistance. The bearish gap that failed becomes support. Same three candles, same prices, opposite role.
A level failing is information. When price closes through a gap that was supposed to hold, the participants who were positioned from it are now offside, and the zone above them becomes the place they exit. That is why an inverted gap tends to reject on the first retest — you are trading into other people's stops, not into a line you drew.
The inversion event
One rule decides whether a gap has inverted, and it is the same body-close requirement that governs the rest of the framework.
| What price does | Result |
|---|---|
| Wicks into the gap and reverses | FVG held. Still a normal FVG. |
| Wicks fully through and closes back inside | FVG held. Still a normal FVG. |
| Closes a body beyond the far edge | Inverted. Now an IFVG. |
| Closes through, then closes back | Contested. Treat as unreliable and skip. |
The wick-versus-body distinction is not pedantry. Wicks through levels are constant — that is what a liquidity sweep looks like. A body close is the market accepting a price rather than testing it, and it is the only version that signals a genuine change in delivery.
Side by side
| FVG | IFVG | |
|---|---|---|
| State | Unfilled, untested or respected | Violated by a body close |
| Bullish version acts as | Support below price | Resistance above price |
| Signals | Continuation in the original direction | A change in the state of delivery |
| Best used | With the prevailing bias | After a sweep and reversal |
| Entry | CE of the gap, or its near edge | CE of the inverted gap |
| Invalidated when | A body closes through it | A body closes back through it |
| Typical context | Mid-trend retracement | Reversal after a liquidity raid |
Read the "invalidated when" row carefully. The event that kills an FVG is the event that creates an IFVG. They are the same moment viewed from either side, which is why traders who understand one usually misread the other.
Which one to trade
The decision is about context rather than preference.
Trade the FVG when price is still being delivered in the gap's direction and you are entering on a retracement. This is the ordinary case — bias is bullish, price pulls back into a bullish gap, you buy the imbalance.
Trade the IFVG when a reversal has just occurred and you want confirmation it is real. This is the stronger of the two signals, because the inversion is independent evidence that the previous direction failed. The 2024 material makes this the primary entry: mark the first gap before the liquidity sweep, and when the market structure shifts, that gap inverts and its midpoint becomes the entry.
That sequence is worth stating in full, because it is where the IFVG earns its reputation:
- Mark the first fair value gap that forms before the sweep.
- Price raids the liquidity pool.
- Price reverses and closes back through that gap — it inverts.
- The inversion and the market structure shift confirm each other.
- Enter at the consequent encroachment of the inverted gap.
Identifying the gap before the sweep is what makes this falsifiable. Picking an inverted gap afterwards, from the several now visible, is describing what already happened. Mark it first and you are on record.
Walkthrough — both on one chart
An illustrative sequence. Constructed prices, not a recorded trade.
09:12 — NQ is bullish on the 15-minute. A bullish FVG forms at 21,486–21,498 as price drifts up toward the session high.
09:31 — price retraces into it and reaches 21,492, the gap's midpoint, then turns up. The FVG held. That was a valid long entry at the CE, targeting the highs.
09:58 — price runs to 21,566, sweeping the session high. Buy-side liquidity taken.
10:07 — price reverses hard and a 1-minute candle body closes at 21,479, below the entire 21,486–21,498 gap. The gap has inverted. What was support is now resistance, and the close through it coincides with a market structure shift.
10:21 — price retraces up into the inverted zone and reaches 21,492 — the exact same price that was a long entry ninety minutes earlier. Now it is a short entry. Stop at 21,570, above the post-sweep high. Risk 78 points.
11:44 — price delivers to 21,384. 108 points, 1.4R.
The same price served both trades. Nothing about the level changed — only what the market had done to it.
Common mistakes
Accepting a wick as an inversion. The most frequent and the most expensive. A wick through a gap is a test; a body close is acceptance.
Re-drawing the zone after inversion. The prices do not change. Same three candles, same band, opposite role.
Trading an IFVG with no sweep behind it. An inverted gap in the middle of ordinary chop is not a reversal signal. The value comes from the sequence — sweep, shift, inversion — not the inversion alone.
Choosing the gap retrospectively. Covered above, and it is the difference between testing the model and confirming your own bias.
Assuming an IFVG is permanent. It holds until a body closes back through it. Then it is contested, and a zone that has failed in both directions should be left alone.
