VNC over SSH is proving pretty robust for me FWIW. I log to the cloud too, using a log monitoring service which sets up alerts. One situation where I need to log in over VNC is for some reason, IB isn't allowing new API connections. I have to log in to TWS, uncheck "allow ActiveX/socket connections", check it again and all is good. I use the log monitoring service to alert me when this is happening.
This trading week is ending on the positive side with the equity curve growing and the trade statistics remaining unchanged. Super happy about that. Looking forward to next week. 15000 cum net profit on a USD 4500 account.
