Hello, thats my first post.

i try to compile you code, but there are al lot of things that give me an error.
And btw...i found a copy/paste fault.

You write two times: "= series(LowPass(Price_D1,200));"

I'm not clear with the variable "LOOKBACK" and "LookBack" in the Indictator, because you don't init it somethere.

Nice regards
Will
