i know what it is. your OP added no context. it's available intraday on bloomberg. someone speculated that bloomberg is doing their own calculation for it.
I read it's not tradable and doesn't have options. I found a chart on the investing app. It's just an index created for the 0dte frenzy.
For the freebie crowd (delayed 15 minutes):- https://www.cboe.com/us/indices/dashboard/VIX1D/ Also Bloomie had a blurb about it:- Curious whether they will also have a VIX of that, like $VVIX is to $VIX itself?
I see a delay of 15 minutes, do you say it in the paid version? In the Suntrader link the graph seems delayed but above shows the real figure
