FYI:

I started a demo run of Z2fx last week. It showed a day of H4 bar info, then "[zzz] Weekend until 15.10.0213". Next message (not sure when it displayed) was "Broker: Account - Connection with trading server" and the rest was cut off and I don't see any way to read the rest of it.

The "Server" message was still "Weekend" (on Monday night US time).

I stopped and restarted the test and now it's OK.
