vols were 17 went to 23 and then to 20 after the split and I covered most of my position at 18.5 yesterday.
Realized Vol came in a lot after the split.
I didn't notice and change in the quality of my fills.
Commissions are higher but my pnl vol exceeds commissions substantially.
23% was unsustainable, but look at GOOG's 40-50 pt range after their 2 for 1 split. Now it's trading at nearly one year lows on vola on a $90 spot.
