What makes a Fair Value Gap genuine?

Candle one and candle three have to leave a genuine void between them: candle three's low above candle one's high for a bullish gap, or candle three's high below candle one's low for a bearish gap. If the two candles overlap at all, there is no gap regardless of how large candle two looks.

Where does a Fair Value Gap fill?

The 50% level, the midpoint of the gap, is the level most setups treat as the first genuine test, often called consequent encroachment. Full fill is the far boundary, the original candle one price.

Is this a genuine Fair Value Gap, and where does it fill?

The market doesn't reward being right. It rewards managing being wrong, cheaply.

A Fair Value Gap is the void left between candle one and candle three when candle two moves fast enough that the two outer candles never overlap. Enter the high and low of candle one and candle three; candle two's own high and low don't matter to the test.

Your Result

Enter both candles' highs and lows to check for a genuine gap.

How this is calculated

Bullish FVG: candle three's low sits above candle one's high. The gap runs from candle one's high (the bottom of the void) up to candle three's low (the top of the void).
Bearish FVG: candle three's high sits below candle one's low. The gap runs from candle three's high (the bottom of the void) up to candle one's low (the top of the void).
If neither test passes, the two candles overlap and there is no Fair Value Gap, no matter how big candle two's range looks. Wicks on candle two are never part of this test.
The 50% level, often called consequent encroachment, is the midpoint of the gap and the level most setups in this pack treat as the first genuine test of the gap. The full-fill level is the far boundary, the original candle one price the gap has to reach to close completely.
Fill progress, when you enter a current price, is measured from the boundary price first traded back into the gap toward full fill, clamped between 0% (untouched) and 100% (fully closed).

Risk & liability disclaimer: This calculator does arithmetic on the prices you type in. It cannot tell you whether a gap will fill, partially fill, or hold as support or resistance, since that depends on market structure and order flow this tool has no way to see. Nothing here is a recommendation to trade any gap in either direction.
