Double top or bottom

An indicator of patterns #13 - #20 ("Double Tops" and "Double Bottoms", types Adam-Adam, Adam-Eva, Eva-Adam, Eva-Eva) from Encyclopedia of Chart Patterns by Thomas N. Bulkowski. Adam - sharp tops/bottoms, Eva - flat ones.


  • Alerts - show alert when an arrow appears  
  • Push - send a push notification when an arrow appears (requires configuration in the terminal)
  • PeriodBars - indicator period
  • K - an additional parameter that influences the accuracy of pattern shape recognition. The smaller the value is, the smoother the row of peaks/valleys should be, so fewer patterns will be recognized  
  • AdamAdam - type Adam-Adam
  • AdamEve - type Adam-Eva
  • EveAdam - type Eva-Adam
  • EveEve - type Eva-Eva  
  • ArrowType - a symbol from 1 to 17
  • ArrowVShift - vertical shift of arrows in points  
  • ShowLevels - show levels
  • ColUp - color of an upward line
  • ColDn - color of a downward line
  • Auto5Digits - automatic multiplication of ArrowVShift by 10 when working with 5 and 3 digit quotes.

Note. Arrows appear on a forming bar and do not disappear.

It cannot be guaranteed that the indicator recognizes the patterns exactly as implied by the author.

Recommended optimization parameters: PeriodBars, K and different combinations of parameters AdamAdam, AdamEve, EveAdam, EveEve.
