Evaluate the Weighted Moving Average(WMA) where the weights associated to all the elements of
the historical values are given and the WMA is evaluated for all periods for which there is sufficient
historical data.

# Syntax

#### Parameters

*s*
- An series of historical values, where the first element corresponds to the market
on the last period, the second term to the value on previous period and so on.
*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.
*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.
*lengthOfMA*
- The number of periods over which the weighted moving average is evaluated.

#### 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.
