Has anyone an idea what is happening?
I just about dismissed it completely because when I loaded it the FM line wasn't working so I thought the noisy deriv line was the main signal. I changed the deriv color so it shows up on dark mode, then realized the FM line shows up on other symbols.
If the price is changed to log it seems to work on everything.
src1 = input(title="Source", type=input.source, defval=close)
UseLog = input(true, title=' Use Log Price?', type = input.bool)
src = UseLog ? log(src1) : src1
deriv = change(src, input(1))
