Horn shaped top or bottom

An indicator of patterns #28 and #29 ("Horn bottoms" and "Horn tops") from Encyclopedia of Chart Patterns by Thomas N. Bulkowski.

Parameters:

  • Alerts - show alert when an arrow appears  
  • Push - send a push notification when an arrow appears (requires configuration in the terminal)
  • BarsInsideFrom - minimum number of bars between the tops
  • BarsInsideAdd - the number of bars between the tops can be in the range from BarsInsideFrom to
  • BarsInsideFrom+BarsInsideAdd-1. If the value is -1, the number of bars can be any no less than BarsInsideFrom
  • K1 - an additional parameter that influences the accuracy of pattern shape recognition
  • K2 - an additional parameter that influences the accuracy of pattern shape recognition
  • ArrowType - a symbol from 1 to 17
  • ArrowVShift - vertical shift of arrows in points  
  • Auto5Digits - automatic multiplication of ArrowVShift by 10 when working with 5 and 3 digit quotes.
Note. Arrows appear on a forming bar and can disappear during bar formation. Notification (Alerts and Push) are generated based on a formed bar.

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

Recommended optimization parameters: BarsInsideFrom, BarsInsideAdd, K1, K2.
