dotnetCHARTING Namespace > FinancialEngine Class > LinearMovingAverage Method : LinearMovingAverage(String,Series,ElementValue,Int32) Method


seriesName
The name of the series which will be displayed on the chart, i.e. its label.
s
A series where the first element is the price on the earliest period, the second element is the price on the next earliest period and on so.
elementValue
Specifies the particular element value (for example High, Low, Close or Open of the FinancialEngine 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 moving average is evaluated for each period.
Returns the value of the Linearly Weighted Moving Average(LWMA) for all periods for which sufficient historical data is provided.

Parameters

seriesName
The name of the series which will be displayed on the chart, i.e. its label.
s
A series where the first element is the price on the earliest period, the second element is the price on the next earliest period and on so.
elementValue
Specifies the particular element value (for example High, Low, Close or Open of the FinancialEngine 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 moving average is evaluated for each period.

Return Value

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 priceSeries 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.
