I upgraded my trading computer to Build 989.4, the latest standalone version for Windows. I do most of my trading with my own apps via the API. The installation ran normally, and the TWS looked and acted properly. When my bots placed orders just before the close, the TWS popped up a message box and failed to send in my orders. This is a catastrophic error that could cost me a lot of money. Be advised that Build 989.4 will likely break any apps that use the API.
