Trade rules

DirectionLong (buy)
EntryIn an uptrend, a gap down (the candle's high below the previous candle's low). A candle CLOSES above the gap candle's high within 3 candles. Target: the close before the gap.
Cancelled ifPrice trades below the gap candle's low before that close.
TargetGap fills, projected from the breakout
3 common mistakes
  • Buying the gap-down open with no confirmation: some gaps never fill.
  • Aiming past the prior close: the classic trade ends when the gap is filled.
  • Trading gap fills in a downtrend: this setup needs an uptrend to return to.
