Trade rules

DirectionShort (sell)
EntryTwo equal main swing lows make support. After a close below it, price drops 2% (Bitcoin) or 2.5% (stocks) further, then rallies to within half an ATR of the level within 30 candles. Within 3 candles of touching it, a candle CLOSES below the previous candle's low.
Cancelled ifA close more than half an ATR above the old support, a candle trading above the retest high before the entry, or no retest within 30 candles.
TargetRange height, projected from the breakout
3 common mistakes
  • Shorting the first touch of the old floor before any candle closes back down.
  • Drawing the level after the fact: it has to be a floor that held at least twice.
  • Holding the short after a close back above the old support. The flip failed.
