method set_tolerances(this, tolerance_Bmin, tolerance_Bmax, tolerance_Cmin, tolerance_Cmax, tolerance_Dmin, tolerance_Dmax)

  Namespace types: Match

method add_if(id, item, condition)
convenience function to add a search pattern to a list, only if given condition (input.bool) is true
  Namespace types: Pattern[]

Pattern
  type to hold retracement ratios and tolerances for this pattern, as well as targets for trades

Config
  allows control of pattern plotting shape and colors, as well as settings for hiding overlapped patterns etc.

Match
  holds all information on a Pattern and a successful match in the chart. Includes XABCD pivot points as well as all Line and Label objects to draw it
