Do you have a multi key? meaning you can send to various ECN's at once? I find that when this happens it happens because of the lag in the routing, i.e. I send to EDGX and i get all my EDGX shares but none of the shares on the other 2 NSDQ or ARCA.
If you set up a multi key it will send your shares to all three at the same time, so it will go to EDGX, ARCA, and NSDQ, and they wont have time to pull, i have found that this greatly increases my chances of getting the shares which are there.
You just have to be quick on the math, and risk overfills at times because if you want 2000 shares you would have to key in 700 cause its sending 700 to all three ecns. You may risk getting overfilled by 1-200 shares at times, but its better then taking a swipe at a level for 2k only to miss and post on the offer and watch it fall 5-6 ticks.
you got to remember too that sometimes you actually are going to be just a millisecond or 2 late, especially when looking at punching a level with a bit of size on it, because there are probably 300 other traders looking at the exact same thing, all waiting till it gets ugly to punch the level.

My god.. how does the SEC let this go on ?
Happening ALL THE TIME NOW. You try to lift a bid or offer, and miraculously it is lifted or smacked a milli second after you press the button, putting you on the bid or offer.
I cant say every HFT program does this but THIS NEEDS TO END.
ITS ILLEGAL.
