Definition
A look-ahead window is the stretch of candles after a gap that is watched to see whether price returned to it.
The site's touch and fill counts use a window of 8 candles, which is 120 minutes on the 15-minute charts. A gap with fewer than 8 candles left in its day is left out of those counts, because it was not watched for as long.
