I can't believe this thread isn't huge, I guess there aren't as many listed scalpers out there as I think.
I started noticing this in the Broker stocks a week and a half ago, they are definately harder to trade now. I heard a rumor back then, that it was new specialist software that tracks the futures, probably the e-minis, and links it with their bid ask. This is what feels like is happening. the bid ask will be
40.10 x 40.15 with size 40x45 and the minis will tick up a point and suddenly the bidask is 40.20x40.22 with size 35x50. There will be no print of the 40.15 size, he just changes the bid ask. It really makes entering stocks impossible, and then with the issue of not getting price improvememt, and prints outside the bid ask out of nowhere, which I also have noticed, it makes me think Nasdaq time, or maybe futures?
I think the NYSE is making a big mistake, I bet if you add up all the scalping volume on the NYSE it is very significant.
What can we do about this guys? Or how do we beat it?
