Fair Value Gap (FVG)

Updated 2026-09-20

Definition

An area of inefficiency in a three-candle sequence: the first candle's high is below the third's low (bullish) or vice versa.

Why it matters

It's hypothesised that price tends to return to fill it at least partly. It must be filtered by size (for example ≥ 0.3 × ATR) and measured: how many FVGs fill and how fast is told by the data, not opinions.

Practical example

C1 high 1.0960 and C3 low 1.0972: a 12-pip bullish FVG between 1.0960 and 1.0972.
