Description: A well-known and vastly used momentum indicator, a Relative Strength Index (RSI) by J. Welles Wilder Jr., aims to evaluate the current price to its oversold/overbought area while giving an overview of bearish/bullish momentum. In this indicator, simply adding the super-smoother function (John F. Ehlers) was applied to the RSI line to create a more smoothed line and reduce its noise.
