  Why would anyone but high-frequency traders want to use it? And in that case, HFT would be on aggregate a losing proposition.

    because that's were most of the trading volume is going to be.

      I don't know. I think ~15% of the daily volume is traded at the opening/closing auctions. Why do you think the end-of-second (or end-of-tenth-of-second) auctions won't be popular?
