LinearlyWeightedMovingAverage(Series,Int32) Method

Returns the value of the Linearly Weighted Moving Average (LWMA) for all periods for which sufficient historical data is provided.

[C#]
public static Series LinearlyWeightedMovingAverage( 
   Series s,
   int lengthOfMA
);

Parameters

s: A statistical series.
lengthOfMA: The number of periods over which the moving average is evaluated for each period.

Return Type

A series where the first term is the LWMA of length lengthOfMA for the latest period, the second term is the LWMA of length lengthOfMA for the previous period and so on.

Exceptions

Exception	Description
ArgumentException	Thrown if the series `s` is empty or if its length is less than the `lengthofMA`.

Remarks

The Linearly Weighted Moving Average (LWMA) weights the time series by assigning a weight of 1, to the oldest price and a weight of 2, to the second oldest price and so on... Until the weight of the most recent value is assigned to be the parameter lengthOfMA, after which the LWMA is given by the sum of the weighted prices divided by the sum of the weights. This indicator then shifts the window (one place back) over which the MA is evaluated and the indicator is then re-evaluated.
