how to see many symbols in one window? (Comparision)

 

Please help!

I know how to import into history center many additional "offline" symbols (other from given by broker's server). and how to see them as "offline" charts in MT4.

But I would like to heve a tool to compare visualy price action of any of these offline symbols in one window (as a cluster of lines ,and max 8 symbols simultaneously).

- best in additional indicator window created for that purpose (because I need "Main" window for " "main" symbol).

If you know such a script..... PLESE HELP!, I would be very thankful.
