Operating System support
If someone from CQG reads this, could you please tell us why you can't develop the various trading apps in Java so that instead of only having a Windows version, the rest of us in the *nix world won't have to install a VM just to run Windows?
Case in point: MotiveWave.
I understand there's a lot more Windows users out there, but nonetheless, this is 2016 and CQG has been in business for... how long? Come on, seriously.
