Check the tape. Did the stock get taken by someone else? Then maybe you were a hair slower than someone else. It could also be that you may be getting slightly delayed data to your execution platform. The stock that was offered also could have been cancelled before your order got to the offer. I've received a lot of partial fills on orders like this because someone else was faster to the stock.
a stock was at 40.10 by 40.13 I had order to sell 200 shares at 40.26. I get filled and i noticed the bid offer really didn't change. what was the reason for this? did someone just sweep thru the openbook and the offer wasn't reflected?
This happens to me a lot. The only difference is that I don't place my limit out. I place it when the price nears my target. Because of this I miss the prints that go off on nyse above the best offer. For ex. I am in at 90.50 and I am waiting for the inside quote to get to 91. Instead, there is a huge print at 91, while the stock is still quoted by nyse at 90.60 x 90.70. And then the stock does not go up there and I am left with my shares. This really upsets me. Because if I had placed the order at 91, I woulda got filled. Its one thing for the stock to NOT go up to where you want but it's a totally different feeling when it prints the price that you want and yet you have no chance to get it. It's a terrible feeling... Why is this happening so much lately?
A maximum of 10 secs. If the specialist feels it should go back to electronic he can manually reset it. Check out the Oct 03 Webinar or the NYSE site attached. http://www.nyse.com/marketinfo/hybmarket/1126821290301.html
be extremely careful with arca market orders on nyse stocks that aren't super thick. on friday i was chasing wy which took a fast tumble and was heading up. because i knew sdot would hold i sprayed a few market arca orders and got fills 35 cents above the ask. i never saw any other trades there but me. i should have thrown arca limit orders 10 cents above
some say volatility will severely go down with new hybrid, how is this explained? with it being more electronic with no specialist to neutralizee, the volatility should skyrocket. prints that rip thru the book and come right back down etc...
it depends very much on the stock...gg and ma are both hybrid, yet gg is very orderly and tradable, ma is a pure beta gamble from open to close.
Well like I said before in previous threads, you will notice little difference in stocks that have already been run via electronic orders from hedge funds & abrs, mainly the metals & homebuilders in my experience. There was a negative effect but to a lesser extent. Still, it's a lot more negatives than positives, sometimes even no positives. That has been the trend for 5 years. I personally believe that the daytraders are labeled as targets by the big boys, mainly GS. Daytraders been the targets of specialists ever since the institutions got sick of the NYSE bullshit. Now, GS wants to do what they did with Nasdaq. But the kicker is that GS, Merrill, etc. have been getting into the clearing business. It's a clever & elaborate plan, they do not exactly want you to blow out and take big hits.
those price mprovements sound like fun... Im gonna start placing orders way out of the bid ask, c if fish myself something...
