Quote from bonds:
To clarify, I tried to hit the bid with 5000 shares showing on the bid at 13.32, i got no fill whatsoever, and not a single print went off...
ie the bid just disappeared and all of a sudden it instantly went to 13.30 on the bid and 13.31 on the offer.
Another thing ive noticed is that sometimes i put a bid out on an ecn that does not have any bidders... then instantly there are other bidders along side with me and they have priority over me
ie there are no bids on NYSE and i bid 5000 NYSE then all of a sudden there is 20000 on the bid and prints go off and i am not getting any fills...
i can only assume that when i route my bid an hft algorithm sees it and decides it wants to get priority ahead of me?
and from my experience there are posted bids/offers that every time you try and hit them they disappear. i have noticed this regularly, i thought this was not allowed but it is happening over and over to me and im sure others as well.
"tried to hit the bid" or did you actually hit the bid?
