Definition

The middle candle is the second of the three candles in a fair value gap, the one that moves away from the first candle faster than the third lets price come back.

Its range is not part of the gap. The gap is the space between the high or low of the first candle and the low or high of the third, and the middle candle crosses it.

Because it usually carries the move, the middle candle is where displacement is measured on this site.

EURUSD, 2026-10-13, 06:00 to 18:00 UTC. Real candles: Dukascopy 15-minute candles, read 2026-10-31. Fair value gap by the three-candle wick rule, no minimum size. Each box runs from its gap until a later candle trades through its far edge, or to the end of the chart.

EURUSD, 13 October 2026, 15 minute candles, 06:00 to 18:00 UTC. The rule finds 6 gaps in this window. A bullish gap whose third candle opens at 07:00 UTC runs from 1.11769 to 1.11780, a size of 0.00011 in price. A candle opening at 09:30 UTC traded through its far edge, so it is filled.

The window was chosen because it shows the term clearly. It is one chart, and it says nothing about what the next gap will do.
