Quote from e-miNY:
Hey Don, do you agree with the statement that an offer (at least a big one) is 99% bluff? Would a professional seller who thinks prices will go down be offering? Wouldnt they just hit the bid? The reason they are offering is because 1) they are not a aggressive seller (maybe they have already put on half the position). 2) they want to buy it - they bluff some newbie into offering in front of them so they have some supply to buy from.
Is there any more reasons for a big offer?
Quote from Avid_Consumer:
thanks vm for the info Don. i just don't understand why they would need to do this, who it really benefits. i mean why should one participant in the whole market be able to shut out anyone else even for a second as they attempt to match their orders. they're just one market center.
i guess the question is really about ecn 'interference', what would an example of that be?
it poses a real risk, if one market center has the power to lock out all the others at his discretion. what's to prevent abuse of this power under emergency conditions? i can't think of a rational reason why they should have it in a free market
they can cease my ability to exit a position at any competing mkt center, at will. why can't i shut him out when i feel like it.. they're supposed to add liquidity, not block it
thx again

I understand from Hybrid system that from now or from the beginning of 2007 these trade throughs should not happen anymore. So can anybody explain why it still happens that there is for example
ecn bid 10.00
nyse bid 9.97
and trades are at 9.97
Thanks
Quote from Bitstream:
u can see it for uself if it is a scare print: just buy the bid and if u get a fill u know u are wrong and get out on the offer @b/e. i do it sometimes cuz it can be real resistance, especially at round numbers.

Quote from Scalper007:
No way! Trading NYSE stocks is much harder and much more dangerous than Nasdaq for all I know. In nasdaq, you can get in and out easily without any interference. In Nyse you got the specialist spreading up and down all over the place; crossing the markets preventing you from executing on the ecns; and here's what happened to me in my effort to test hybrid stocks such as MA the past couple of days: I buy it at 84 and the stock is trading around 84 on nyse AND the ecn, and guess what..All of a sudden the pervert comes in with a bid of 83.60 and an ask of 83.63 crossing the ecns even though there are bids on the book...Thats an immediate 40 cent loss out of no where. This kind of nonsense never happens in nasdaq. Yes, stocks fall 40 cents in seconds, but it falls through all the bids. It doesn't just jump from 84 to 83.60 when there are bids!! Nyse is a BIG BIG mess. And maybe the hybrid isn't just what I thought it to be. Did anyone else see this nonsense in MA? I seem like the only one who sees this.... I mean if this is what hybrid is supposed to be then nyse traders are in for a big surprise.. I am beginning to wonder if the hybrid system's immediate fill has any value when the fills are just totally nasty.
Quote from Don Bright:
Pretty hard for a Specialist to manipulate much (especially these days). They cannot initiate a downtick, cannot initiate an uptick, and can only participate with other orders except when making a fair and orderly market.
That being said, the automated programs that are triggered do seem to have that ability, but these from hedge funds and other program traders.
IMO,
Don
I sure hope to hear some feedback on this one.Quote from Scalper007:
What about those huge sizes that the specialist flashes and just when you wanna hit it, he removes it. So thats not the specialist? It's a program? I see this often in lvs and x...If the specialist is doing that, Isn't that manipulation?
