UpperBollingerBands(SeriesCollection,Double,Int32) Method

Evaluates the position of the Upper Bollinger Band for a given standard deviation level.

[Visual Basic]
Overloads Public Shared Function UpperBollingerBands( _
   ByVal sc As SeriesCollection, _
   ByVal standardDeviationLevel As Double, _
   ByVal lengthOfMA As Integer _
) As SeriesCollection

[C#]
public static SeriesCollection UpperBollingerBands( 
   SeriesCollection sc,
   double standardDeviationLevel,
   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.
standardDeviationLevel: The (positive) number of standard deviations which the lower band in shifted from the moving average.
lengthOfMA: The length of the moving average used within the evaluation of the Bollinger Bands. Note that this also corresponds to the length of the period over which the standard deviation is evaluated.

Return Type

A series where the first term corresponds to the value of the Upper Bollinger Band for the latest periods, the second terms to the previous period and so on.

Exceptions

Exception	Description
ArgumentException	Throw if the series historicalPrices is empty or if the number of standard deviations given (i.e. the parameter standardDeviationsLevel)is a negative number.

Remarks

Please note that by standard deviation level we not only refer to the number of standard deviations shifts away from the moving average at which the Higher Bollinger Band is drawn but also the number of time series points which are used in the evaluation of the standard deviation and the moving average.
