I have a feeling all this flash order bs came into the news because somebody at NYSE or others associated with them wanted to screw the other "exchanges/ecn's" & they figured this was the best way to do it...make them look bad.
Who knows, maybe NYSE secretely "flashes" orders to their #1 patron, GS!

dude, how can they 'sell' your information if you keep your trade to yourself until you want to execute?
your 100 shares of SIRI is not of interest to the pros.
Quote from pacific7:
I'm trying to find out if any other traders have been having problems with stocks that appear to have a lot of liquidity on level II only to place a market order to close a position, and the big liquidity vanishes out of thin air instantaneously??? I usually end up getting filled anywhere from 3,4,5 even 10 cents out of the money from where there was apparent big liquidity on BOTH sides of the level II when the order was sent.
Could this be the broker/dealer with some sort of blackbox scalping or shaving my trades, the broker dealer's clearing firm shaving my trades, or an outside algorithmic trading systems showing apparent liquidity for the stock then picking up on my order (from the now much talked about flash orders that high frequency traders pay for) then dropping all of their level II orders? (http://www.nytimes.com/2009/07/24/business/24trading.html?_r=3&ref=business for details on this)
It happens to me about a half a dozen times a day usually on a hot news traded stock with some volume and volatility. I've tried sending the orders on several routes including ARCA, SRDOT, NASQ, ASUROUX. They have all failed me at the worst times, usually when I have decent size in the trade). It's very frustrating and seems like a big rip-off/cheat. I have tried putting out an limit orders and they NEVER gets filled. SOMETHING always steps in front of my order. Even if the limit order is a penny away from the last print something will step in front of it even if it's a fraction of cent better than my order. How does this happen?
I trade with Sterling software. I did read a few posts awhile ago that said brokers with Sterling platform can easily front run there traders orders with black box's, but did not know it this was BS or not.
I'm really trying to get to the bottom of this issue and what's really going on. Any suggestions on changes I could make with order entry would be most appreciated.
Please do not respond to this thread if you have a problem with a certain broker dealer and are trying to throw punch's. Also, no hype from a broker dealer tying to pump their own firm.
Just the truth...!!!!
Thanks

I guess I am slow with this HFT/flash controversy,( sorry, futures trader here), please tell me where I make an error.
From what I understand, flash orders are limit orders placed in the book for a really short time in order to deal solely with other HFTs and spot their algos.
What does it have to do with the fact that MMs get your orders data before it is matched and liquidity goes away when you submit a buy @ ask for example?
Thanks for your help.
