Downgrading to PC, really I see it the other way.Thanks for the reply Simon. I downloaded the installation file this morning but it's called CitrixOnlinePluginWeb.exe - a .exe file is a PC only install program. So it won't work on a Apple Mac unless you use some kind of PC emulation software like Parallels, which is no good for trading as is too slow. So unless you have a native Apple program or plan on developing one I won't be able to use your platform as I've got no intention of downgrading to a PC anytime soon.
