Here we evaluate the Weighted Moving Average(WMA) where for each period for which the
WMA is evaluated the historical terms are weighted in accordance with the same set of weights.
- 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.
- Array of doubles 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.
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.
|ArgumentException||Thrown if the length of the weights and series differ or
if either array is empty.|
