Parameters

s

An series where the first term correspond the latest periods price 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.

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.
