Trade rules

DirectionShort (sell)
EntryThe first candle CLOSE back below the left rim, 25 to 180 daily candles later (30 to 260 on Bitcoin 4H), after a dome 12-45% high with its top in the middle half of that time.
Cancelled ifNo signal if the dome is a spike (under 20% of the candles in its top third), does not fit a smooth curve, or comes back to the rim too fast or too slow.
TargetDome height, projected from the breakout
3 common mistakes
  • Shorting the top of the dome before the rim breaks.
  • Calling a sharp spike and drop a rounding top.
  • Shorting stocks in a bull market without comparing to just holding.
