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



sc
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.
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 considered within the evaluation of the moving average of each of the days on which it can be evaluated.
Returns the value of the Linearly Weighted Moving Average(LWMA) for all periods for which sufficient historical data is provided.

Parameters

sc
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.
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 considered within the evaluation of the moving average of each of the days on which it can be evaluated.

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

ExceptionDescription
ArgumentExceptionThrown 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.
