This script includes MACD histogram plus MFI in four states
All backgrounds are compared to previous bar in +/- 10%
1. Green (green) + Volume + Range (++)
2. Fading (yellow) - Volume - Range (--)
3. False (gray) - Volume + Range (-+)
4. Crouching (red) + Volume - Range (+-)
I allowed myself to take a piece of code of one of the indicators MFI present on Tradingview for the added to a RSI!
I made this srcipt to avoid cluttering the screen, so we can see the oversold / overbought of the MFI without having any additional indicator
