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.

weights

A double array which represent the different weights associated with the given prices.

Evaluation

The FIR indicator is evaluated by the following formula:
FIR = ((historicalValues[i]*weights[0]) + historicalValues[i-1]*wights[1] + ...)/(Sum of weights)
