I thought Z12 was just available for Zorro S. I didn't realize it's available for demo now. It seems Z3 and Z5 are too.
So, how does the VPS work?
I set a VPS up and use a separate one for each FXCM demo?
I tried to set up an Amazon one for free, but it required a CC# and I didn't feel comfortable giving one. So, I found vps.me/ that has free ones too. No CC# required, but "something" didn't work during registration. It's getting late, I'll try again in the morning.
Z3 looks interesting. I'd like to try it and Z12 after getting the VPS going.
