Evaluates the position of the Lower Bollinger Band for a given standard deviation level.
Syntax
Visual Basic (Usage)  Copy Code 

Dim s As Series
Dim standardDeviationLevel As Double
Dim lengthOfMA As Integer
Dim value As Series
value = StatisticalEngine.LowerBollingerBands(s, standardDeviationLevel, lengthOfMA)

Parameters
 s
 A series where the first term correspond the latest periods
values and the previous element is the value of the element before that and so on... The length
of this series is equal to the number of periods used in the evaluation of the standard
deviation and the moving average.
 standardDeviationLevel
 The number of standard deviation 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
Exception  Description 
ArgumentException  Thrown when the series in empty or the number of standard
deviations considered (i.e. the parameters standardDeviationLevel) is not positive number.
