Range(SeriesCollection,ElementValue) Method

elementValue: Specifies the particular element value (for example High, Low, Close or Open of the financial time series) which will be considered within this indicator evaluation. In particular, if you wish to use the element value high then you should pass the parameter High. In a similarly fashion if you wish to use the low, close or open, then you should pass the parameter Low, Close, Open, respectively.

Calculates the range of the series's elements values.

);

sc: A collection of series objects. For example, to evaluate this indicator for two series you will need to pass a series collection containing this two series.
elementValue: Specifies the particular element value (for example High, Low, Close or Open of the financial time series) which will be considered within this indicator evaluation. In particular, if you wish to use the element value high then you should pass the parameter High. In a similarly fashion if you wish to use the low, close or open, then you should pass the parameter Low, Close, Open, respectively.

The range is the difference of a discrete data set is the difference between the largest and smallest members of the data set considered.
