Hi Arnaud,
Is there any way to make this script available for you Currency Index charts? https://www.tradingview.com/script/jMYQyEzE-ZTLs-Percentage-based-Renko-Emulator/
It would be fantastic for these charts in order to visualise instantly which currency is moving most in % terms against the others.
I don't think that's possible. I'll check to be sure
Why are some indicators available and others not?
Because Tradingview don't make them available outside their website
