I am trying to use VIX future live data from IB for which I have real-time prices. It is strange it is working for some contracts (VIX 01-16), but not for others (VIX 12-15). It keeps changing.
If I tried to load VIX 12-15 I receive the following error message:
Error loading chart .... The contract description specified for VIX is ambigous; you must specify the multiplier . (200).
I only have VIX index and VIX futures in my database. I need both. What can I do?
thank you
