RSI IFT (Inverse Fisher Transform) For ThinkOrSwim

[MerryDay]

When I add this Statement to bottom of the Script

I get an error saying only one plot allowed

The ToS platform only gives that error if you stuffed the entire script in the Scan Hacker.
Review the instructions again and follow the tutorial:
