My objection is that selected players get to make virtually unlimited risk free profits by virtue of paying money to the exchanges (co-location). I agree they probably keep spreads narrower but their gains are risk free (front running valid orders) by exploiting timing and fill differences. It should be stopped.
Anyone else check the IEX website? Lots of their customers/endorsements are from big brokerages that excel in predatory HFTing. How does that make sense.
i think it perform very well for Mr Peterffy..but due to exact same problem-complexity of the current markets, groups of 'special interests' and so on ..all this make it really difficult to track IB's performance,but if you trade a lot of stocks and try to analyze next tick after your fill at smart-you will be unpleasantly surprised,that you might be better off by keeping your order open and routed to a common ECN,rather than smart. but at least they(IB) seems to playing it fair,within current bid\ask and offer you an option no to use smart

Does volume at places like IEX get reported in the volume figures? Or are the reported trading volume numbers only for certain public exchanges?
I remember being home in front of my computer watching cnbc and talking to a friend on the phone about WTF was just happening..
