Hint taken.
We have been exploring this possibility for quite awhile. It MAY possibly
show up in a future version, but I'm making no promises. The problem with
adding the capability to manipulate attributes in a formula (color, style
etc) is that it will slow down the native number crunching capability of the
formulas.
If we add this ability to the formula language, it will only be done if we
can minimize the impact on basic mathematical operation performance.

Subject: RE: Setting colour on a multi-plot indicator
Dave,
I am completely lost with your explanation. I know that I can plot a
multicolored oscillator...green for increasing and red for declining simply
by using an if statement to plot or not plot(value zero). This works with an
oscillator simply because I can plot to a value of zero. I can also plot a
third indicator simply by adding a moving average into the formula. This
still requires that I manually select the colors that I desire for each and
yes I can simply this operation by assigning all of this to a template.
But...I still cannot assign the color in the formula which is what I thought
the question was(wouldn't that be nice! Metastock can you take a hint?).
Beyond this point your explanation has me lost. So...if you don't mind would
you give us some more detail?
