I have two questions: 1) Which platform will work without administrative priviliges? Any experiences? 2) Is there any platform that will not automaticaly "update" itself? Or maybe a platform with an option to turn off the "automatic update"?
Oanda's platform works from a web browser and seems to be fine with restricted privileges, although it runs as a Java applet so these will need to be enabled in the browser. It also will connect via a proxy server if a direct connection is blocked by a firewall. The connection to the server can also be switched on and off without closing down the platform.
