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.

weightSeries

A series which assigns weights to the k-th previous historical values for the given period on which the moving average is being evaluated. Here k is just the length of the weights array given.

lengthOfMA

The number of periods over which the weighted moving average is evaluated.

Return Value

Application

Generally speaking the WMA where the weights are all set and the window over which GMA is evaluated is shifted is used when you wish to give emphasis to particular dates.

Note: The length of the weights array must equal or be greater than the length of the historicalPrices series. If it's greater than we ignore the supplementary values.
