Need Help On If function

["neo" <neo1@xxxxxxxxx>]

I am trying to use the If function to break an indicator in two so that it
plots in green if up and red if down. The problem is that I do not see a
pure If function. The only one is an If, Then, Else. If I put a 0 for else
then I get a color dot there I do not want. Is there something that could be
put there that would plot no color?

I have thought about creating a null function that would plot in the same
color as the background. Is there another way?
