Trade rules

DirectionLong (buy)
EntryThe first candle CLOSE back above the left rim, 25 to 180 daily candles later (30 to 260 on Bitcoin 4H), after a bowl 12-45% deep with its low in the middle half of that time.
Cancelled ifNo signal if the bowl is V-shaped (under 20% of the candles in its bottom third), does not fit a smooth curve, or comes back to the rim too fast or too slow.
TargetBowl depth, projected from the breakout
3 common mistakes
  • Calling a V-shaped crash and rebound a rounding bottom.
  • Buying in the middle of the bowl instead of at the rim break.
  • Expecting a quick trade: these take months on a daily chart.
