Library "CommonMarkup"
Provides functions for chart markup, such as indicating recession bands.
markRecessionBands(showBands, lineY, labelY)
Mark vertical bands and show recession band labels if argument showBands is true. Example "markRecessionBands(bar_index,3.0"
Parameters:
showBands: - show vertical recession bands when true. Functionally equiv to no op when false
lineY: - y-axis value for line positioning
labelY: - y-axis value for label positioning
@return true - always answers the value of showBands
