C#  

public static SeriesCollection WeightedMovingAverage( SeriesCollection sc, double[] weights ) 
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.
 weights
 Array of doubles which assigns weights to the kth 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.
Return Value
A series where the first term is the value of the moving average corresponding of the latest period, the second term is the value for the previous period and so on.Exception  Description 

ArgumentException  Thrown if the length of the weights and series differ or if either array is empty. 
I.e. The weights shift with the window of the historical values.
Application
Generally speaking the WMA is used in order to allow more weight to be
assigned to more resent price dynamics. Here the length of the weights array
is used as the length of the period over which the moving average is calculated.
If you wish to control the number of periods used within the moving average
then we refer you to (historicalPrices,
weights, lengthOfMovingAverage)
