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

Remarks

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.
