dotnetCHARTING Namespace > FinancialEngine Class > UpperBollingerBands Method : UpperBollingerBands(SeriesCollection,ElementValue,Double,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.
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.
Evaluates the position of the Upper Bollinger Band for a given standard deviation level.

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.
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 Value

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

ExceptionDescription
ArgumentExceptionThrow 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.
