A touch is a later candle whose wick reaches into a gap.

Definition

A touch is a later candle whose wick reaches into a gap.

It is tested on wicks, not closes. A touch says price reached the gap; it does not say how far in, or what happened after.

GBPUSD, 2026-10-07, 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.

GBPUSD, 7 October 2026, 15 minute candles, 06:00 to 18:00 UTC. The rule finds 5 gaps in this window. A bearish gap whose third candle opens at 09:30 UTC runs from 1.32322 to 1.32358, a size of 0.00036 in price. Price traded back into it as far as 1.32325 and no further, which leaves 0.00033 of the gap untraded, so it is touched and not 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.
