Maybe you can help me with the question about trading on CFE.
With which broker can I trade S&P 500 Variance Futures (VA)?
The market for Variance futures on the CBOE Futures Exchange is unfortunately inactive, there is not much trading if any on most days. (Probably they will be delisted soon?). Some other CFE futures contract (such as VIX) are very active and can be traded for example on Interactive Brokers. The broker is not the issue, it is just that the VA contract is a failure so far.
