Quiet trading in the VIX pit so far Wednesday, with 59,000 calls and 25,000 puts traded in the product. More than half the call volume is due to one spread trade after the Dec 30 – 35 call spread was bought on the index for $1.05, 15000X. It might be a closing trade or a position adjustment, as open interest is sufficient to cover in both contracts and Dec options on the volatility index expire two weeks from today.
