change indicator buffer's color from expert

[Gholamhossein Eslamizadeh]

I add several instance of an indicator by using this command:

 ChartIndicatorAdd(0,0,handle);

from an expert. all of the buffer's color are default and kind of ugly and wage. I should change their color. how to access INDICATOR_COLOR_INDEX property of indicator's using their handles?

please avoid non relevant answers. it is not possible to add input color to the indicators since I don't have its source code.

I cannot use PostMessageW I want to use built in functions since I don't want to use dll allow.

I don't want to build another indicator to just change color of this indicator since it is complex and reduce speed. 

and solutions like these.

thanks in advance.

To control the color of the indicator line from the Expert Advisor, you need to make a setting in the indicator (in the input parameters).

An example of such an indicator: Custom Moving Average Input Color
