public static SeriesCollection LinearlyWeightedMovingAverage( SeriesCollection sc, int lengthOfMA )
- 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.
- The number of periods over which the moving average is evaluated for each period.
Return ValueA series where the first term is the LWMA of length
lengthOfMAfor the latest period, the second term is the LWMA of length
lengthOfMAfor the previous period and so on.
|ArgumentException||Thrown if the series |
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.
