then why do big guys only have this kind of trades on ETF? no futures?
also, why are there only certain data feeds reflect those transactions? stockcharts consistently shows some.
VIX family in the last 8 trading days has made a strong statement - they intend to part away from their 50-day MA. I remember many during Mar of 2009 didn't believe and downplayed the similar moves.
When VIX' making multi-day divergence, you better pay attention and not to second guess too much.
It's time to watch if indices want to stay above their 50 MA now, until VIX family changed their mind.
