Detecting Added Indicators

[beastment]

Hi,

This seems like it should be straightforward, but I can't figure it out.

I have a strategy that adds a custom indicator (spread). However, what I want to do is NOT add the indicator if it has already been added to the current chart (by another instance of the same strategy that has slightly different parameters).

Basically, I want to be able to keep on adding different instance of my strategy to the current chart, but only have it add the relevant indicator once.

I need something like a Plots.Count function.

Any ideas?

beastment, that sort of dynamic adding of indicators could unfortunately not be supported. Perhaps just use two versions of the same strategy, one that would add the spread and the other not, so if the first is already working then only add the second with your changed parameters for execution of signals?
