I always use the '/portable' switch to keep things simple for myself and my programmer. You right-click on terminal.exe and 'create shortcut'. Then right-click on the shortcut and view properties. On the shortcut tab, add the /portable switch to the program target path.

If you were using an application like CNS Autoboot or AlwaysUp, then you could just pass the /portable argument in the launch settings without using a separate shortcut.
I can't really see a good reason why anyone would want to use the roaming folder for terminal data. I have all my mt4s installed outside of the program files folder anyway.
