Having Single instance of Graphic interface

[MHDD]

Hi 

I have a graphic interface wrote with c# for my Expert Advisor. How can I just have a single instance of my interface for all the chart that I want to use my EA?

Thanks for helping to solve this problem

Control the EA from one chart and feed data into it by querrying the other symbols
