Change the chart background from black to another colour?

Hi, 

I spoke to customer service on chat and they informed me this function is not available, it would be great to have the ability to change the colour so I can distinguish between 2 different instruments, of course the symbol name at the top is there, but a more visual indicator would really help.

The CS team advised me to post this request o the forum.   

Regards,
