I made some minor tweaks and enhancements. The main thing is the addition of a Weighted Moving Average (WMA). This really helps track the overall cRSI trend up and down and it can be used as a simple indicator for buying and selling. Buy when the RSI goes from oversold and crosses up through the WMA line. Sell when the RSI goes from overbought and crosses down through the WMA. Also made the cRSI line and the bands easier to see.
