EveningStar

A long rise, a small star, then a fall into the rise.

body = |close - open|, range = high - low, upper wick = high - max(open, close), lower wick = min(open, close) - low

the first bar rises with a long body; the star's body <= star_body_pct / 100 * the first body and its bottom >= the first close; the third bar falls and closes at or below first close - penetration * first body. The star may open at the first close: no gap is required.

A bar whose high equals its low, or that has a missing price, is never part of a pattern. Computed on the prices the bars are drawn with: on Heikin-Ashi or Renko bars those are the built candles.
