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.

lengthOfPeriod

An integer which represents the length of the period over which the indicator will be iteratively evaluated.

Evaluation

The RSI indicator is calculated by the following formula:

RSI = 100 - 100/(1+RS),

where:

RS = (Average of noOfPeriods days up closes) / (Average of noOfPeriods days' down closes),

Interpretation

An RSI above 70 is considered overbought and below 30 is considered oversold.
