For those of you that trade NYSE stocks with non NX size orders- 1100 shares and above, what percentage of the time would you estimate that you receive price improvement when entering limit orders 3-8 cents (varies by stock) through the bid/offer and NOT enabling NX? Recently, price improvement seems to be decreasing, just wanted to some input from the NYSE size traders here. Any comments on this topic/ what stocks give best/worst PI are welcome too.
