Its nearly a year now since the move to half ticks. Without to much analysis it feels like contract volume has dropped overall. My volume and returns for strategies involving the shaz have dropped, not by half but around 30%. Sure the flipping has gone but has all the protesting and resulting change of contract specification left shaz traders more profitable, my guess is no? Perhaps the 12 month period in the change of contract has coincided with a year of much lower volatility than previous which is affecting PnL/activity? Any half tick fans out there?
