Chebyshev-Gauss RSI

The Chebyshev-Gauss RSI is a variant of the standard Relative Strength Index (RSI) that uses the Chebyshev-Gauss Moving Average (CG-MA) for smoothing gains and losses instead of a traditional Simple or Exponential Moving Average. This results in a more responsive and potentially smoother RSI line.

This version is enhanced with features from the built-in TradingView RSI indicator, including:

• A selectable smoothing moving average of the RSI line.
  
• Bollinger Bands based on the smoothing MA.
  
• Automatic divergence detection.
  

How it works:

1. It calculates the upward and downward price changes (gains and losses).
   
2. It applies the Chebyshev-Gauss Moving Average to smooth these gains and losses over a specified lookback period.
   
3. The smoothed values are used to calculate the Relative Strength (RS) and then the final RSI value.
