Well thank you for the forum here, I'm actually unsure of the exact trading of these vehicles so far ???
There appears to be a lack of volume and I am unable to obtain a live quote, also there are additional fees imposed on these vehicles.
So In conclusion at this time, while the two new ETF's VXUP and VXDN may be a closer representation of actual $VIX values, they may not be considered "tradeable".
I guess, yes, it's wait and see approach
