Relative Strength Index + MFI breach

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

เอกสารเผยแพร่:

Small revision of the code, better identifications of the parameters, suppression of some useless lines! The settings for the Upper line and the Lower line of the RSI are always in the "Style" tab
