Parameters

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.

smoothingFactor

The number between 0 and 1 which is known as a smoothing factor. The closer the value is to zero the more influence more resent measurements will have on the EWMA.

lengthOfMA

The number of periods over which the moving average is evaluated for each period.

Return Value
