sc.RangeBarValue

This ACSIL structure member is considered out of date/deprecated. Instead use the sc.GetBarPeriodParameters and sc.SetBarPeriodParameters functions.

sc.GetBarPeriodParameters
sc.GetBarPeriodParameters()

sc.SetBarPeriodParameters
sc.SetBarPeriodParameters()

CCIPredictor Example (from Studies4.cpp ACS folder in your Sierrachart):

Old code
