Why does TWS say that the NDX Index is closed? It is not available in IB TWS. NDX Index c8259.81 How do I know when this kind of thing will happen? Is this a fluke?
Curious. NDX is always available on my TWS with no issues. TWS is installed offline on my PC and the stable version 64 bit TWS 972. Today had issues with server freezing with version TWS 978 and reverted down to 972. No further server freezes.
