Short VX futures as in short the VIX as in short vol. The short vol is the most crowded trade in the world and in fact is the most crowded traded in history.
to really give the whole story i would suggest looking at the complete report, including commercial.
this has been lopsided many times to the non commercial end re short vol ; but despite that most will find no edge in fading that.

What does commercial vs non commercial mean on that?
"commercial" is a trader or entity who has been classified as using that "particular" instrument for hedging purposes.

I think that crossing the spread turns the trade into a statistical nightmare. Risk / reward / payoff.
I always wondered what sellers do, do people even take their offers at the mid deep OTM?
Built into price--not IV. Expanding on my 50 delta option example, an actual 50 delta option has a range of possible values at expiry between 0 and lots. Its value is highly dependent on IV. A close approximation to a binary trade would be a vertical spread with the underlying splitting the two strikes which will be valued at half the width of the strikes (let's just ignore skew for a moment). This is independent of IV.
So the outlier outcomes and impacts are built into the price--not IV.
There is so much bad information in your posts I would highly recommend reading "Dynamic Hedging" as a starter and maybe even a Statistics for Dummies book. I'm being serous. There are some real fundamental flaws in your knowledge of simple math that I strongly advise you to fix sooner rather than later.
