It's not often I know the answer to a question, so:
"Up" and "down" aren't words that Amibroker recognizes. You need either
to define them before they are used or to substitute something else for
them that AB will understand. At a guess, the technique defines "up" as
C > O and "down" as C < O. [It could be C > Ref(C,-1) or C < Ref(C,-1).]
So before your Plot() statements, add these lines:
up=C > O;
down=C < O;
Alternatively, you can change that part of the Plot() statement to:
|IIf(C > O, colorGreen, colorRed) .
Note that you don't really need nested IIFs to get the job done. This
version will also color bars red if C==O. If you want C==O to come out
green, you can use:
IIf(C < O, colorRed, colorGreen) .
Good luck with it.
