I checked bloomberg few hours ago, to follow up on other volatility futures, and here are today's numbers:
|SPAVIX (S&P/ASX 200)||0||N/A|
Unfortunately, it looks like most of the international volatility futures did not take off. VNKY looks solid, but volume still disappoints. India VIX is still in a honeymoon period; let's hope the volume stays.
* open interest as reported by NSE stands at 372750, but I believe that number is OI * 750 (contract size) I reported adjusted number for consistency.
