Parameters

seriesName

The name of the series which will be displayed on the chart, i.e. its label.

s

The financial series where the first element is the traded price on the most recent period, the second element is the traded price of the previous periods and so on, for the asset under consideration.

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.

Return Value

Evaluation

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