I am not sure why it is so difficult to explain this to you, apparently you have never kept your TWS running overnight.
There is a difference between TWS on your PC logging off and TWS server resetting at 12AM Eastern. When the server comes back, your TWS is still running and it will reconnect to the server automatically. There is then a problem of the server running in syn with your TWS. The following picture may help.
OK, I get it now. A long time ago I changed the log off time to 12:00 Midnight Eastern. So what happens is that at Midnight my TWS logs off. Evidently the server reset takes place at or around the time my TWS is logged off. Later, if there is something I'm watching, I log back on. So the bottomline is that in my case my log off time and server reset are at the same time, and therefore I was not aware of what you were describing.
In terms of orders, I generally do not like to trade afterhours, but occasionally I leave an order in. Then I shut TWS down. When I turn TWS back on in the AM, if there was an execution I hear the ding when TWS opens. But I always look in the Account Window under the portfolio section to check that. Up to now at least there has been no problem.
By the way, I did read the links you provided. Very helpful. But if I understood correctly IB has already corrected the issue. Is that not the case?
