Indicator: MFI or RSI enclosed by Bollinger Bands

Indicator allows choosing either MFI or RSI and draws a BB over it to identify oversold / overbought conditions.

Oversold/Overbought breaches are highlighted using different colors for easy identification. Has helped me a lot during sudden pumps to identify the tops, hope you find a use for this.
