Hello IB API traders, I have an automated trading system ( excel DDE )that cancel/replace limit orders in a dozen of markets and this afternoon TWS froze, sound alerts for market data and trades didn't work, orders were filled and when I realized it 5 minutes later, it was too late.... I lost 2.5K$. It is the first time it causes such losses. Most of the time I hear the sound alert for market data, restart TWS if I can't cancel orders and in the worst case, I just get filled in a few markets leaving me with small losses. How do you handle TWS freezes? What can be done? Is there some 3rd party softs that can alert you if a program ( tws ) is not working well/ losing connection? Thanks a lot for your help.
