How to Identify a Valid ICT Fair Value Gap — Not All FVGs Are Equal
You can identify FVGs correctly but still lose money — because you are trading invalid ones. This guide teaches the specific criteria that separate high-probability FVGs from noise.
The most common mistake made by traders who have learned about Fair Value Gaps is treating all FVGs equally. They mark every three-candle imbalance on their chart and trade every return. The result is a mixed win rate and confusion about why "the FVG didn't work." The truth is that FVGs exist on a spectrum of validity — and only the ones meeting specific criteria have the institutional significance required to produce reliable reactions.
Criterion 1 — The Displacement Requirement
A valid FVG must be created by a genuine displacement move. A displacement is a series of large-bodied candles with minimal overlapping wicks that move aggressively in one direction — typically 2-5 candles that show clear directional conviction. If the FVG was created by a single average-sized candle in the middle of choppy price action, it does not carry institutional significance.
The test: look at the candle sequence that created the FVG. Are the candles large-bodied? Do they show directional conviction? Is there a noticeable increase in momentum compared to the surrounding price action? If yes — genuine displacement, valid FVG. If no — the FVG is noise.
Criterion 2 — Higher Timeframe Alignment
A valid FVG must align with the institutional order flow on the higher timeframe. A bullish FVG on the 5-minute chart is only valid if the 4-hour or daily chart shows a bullish institutional order flow. Trading a bullish 5-minute FVG in a bearish 4-hour structure is one of the most common causes of FVG trade failures.
Before trading any FVG, ask: what is the direction of the nearest 4-hour OB or FVG? What is the daily bias? Does this 5-minute FVG point in the same direction? Only if the answer is yes to both questions is the FVG alignment sufficient for a high-probability entry.
Criterion 3 — The First FVG in the Sequence
When a displacement move creates multiple FVGs within the same sequence, only the first one — the 1st Presented FVG — carries full institutional significance. The first FVG represents the first opportunity for the market to reprice the imbalance. Subsequent FVGs within the same displacement have progressively lower probability because the same institutional interest that created the earlier FVGs is diminishing with each one.
Criterion 4 — No Prior Violations
A valid FVG must not have been previously violated. Once price has traded fully through an FVG — through both the near edge and the far edge — the FVG has been mitigated. A fully mitigated FVG is no longer a valid entry zone. It may have become an Inversion FVG (a zone that has flipped from support to resistance or vice versa), but the original bullish or bearish character has been extinguished.
- diamondCheck: has price previously entered the FVG and traded through more than 50% of the gap? If yes, the FVG is partially mitigated and carries less weight.
- diamondCheck: has price traded through the full FVG (from near edge to far edge) at any point? If yes, the FVG is fully mitigated and should not be traded in its original direction.
- diamondCheck: has the FVG become an Inversion FVG? If price has traded completely through it, it may have flipped — in which case the original FVG zone now acts in the opposite direction.
Criterion 5 — Session Timing
Valid FVGs for intraday entries should be created and tested during active sessions — London and New York. An FVG created during the Asian session low-volume period or during a bank holiday has less institutional significance because the institutional participation required to create a genuine imbalance was not present at the time of creation.
Create a checklist for every FVG you consider trading: (1) Was it created by a genuine displacement? (2) Does it align with the HTF bias? (3) Is it the first FVG in the displacement sequence? (4) Has it been previously violated? (5) Was it created during an active session? Only FVGs passing all five criteria qualify for trade consideration.
