Version 4 is Buggy
I cannot do much with this. Cannot roll futures, and cannot see the VIX term structure. The quotes in the position screen are usually off, sometimes by a lot. Fortunately just logging in using a browser works. Quite amateurish. The new version also freezes all the time when fetching positions or balances.
