How to set an EA based on indicator colour changing

[FXAmoneymaker]

HI is it possible to set an EA based on indicator colour: like if the indicator changes to red going down ( it sells ) if it changes to green goin up ( it buys )
if that is possible to set it that way, can you please share your settings using any indicators just to get an idea how to do it.

@fxamoneymaker Check available buffers if you have the source code of the indicator. usually there is at least 1 buffer that mybe is not visual but indicates the trend (which then will be painted in different color). That's how I do so.

Of course you need some basic knowledge to do so.

In case you don't have the sources, there might be a way to read the color from a chart object, but that's a different story and not what I use in general.
