C#  

public static SeriesCollection GeometricMovingAverage( SeriesCollection sc, ElementValue elementValue, int lengthOfMA ) 
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 periods on which it can be evaluated.
Return Value
A series where the first term corresponds to the Moving Average on the last period and the previous value is the value of the Moving average on the previous period and so on.Exception  Description 

ArgumentException  Thrown if the series is empty. 
Illustration
If we are considering a traded asset and the periods considered are days then by passing
an array containing the closing daily prices of a given asset, and by choosing to use the
5day Geometric Moving Average (i.e. passing the length of the GMA of 5
), then
this method will evaluate the Geometric Moving Average (GMA) for all days for which the
closing price on that day and the four previous days is known.
