Who can see the exact qty and price of orders posted overnight on stock exchanges? (I have little experience in stocks so please be patient )
If you mean GTC orders for the next day, and things like that, I assume any broker can see the orders of its own system at least without trouble.
Here is the quote from nyse: At 4:00 a.m. ET, Limit Orders designated for the Opening Session are matched and executed in the Opening Auction. NYSE Arca will accept orders for the Opening Auction beginning at 3:30 a.m. ET, and will continue accepting orders until the Opening Auction is conducted. I mean the whatever orders described above.
The exchange or ECN only accepts orders during a certain time period. Your broker uses something called an order routes to route your orders to the exchanges. If your order is entered outside of normal business orders for the exchange/ECN, your order will reside in the order router until normal business hours, then be sent to the exchange/ecn. So to answer your question.....no one can "see the order." Your broker holds that order in their system until the exchange/ecn opens their pipes. Then, anyone the pays for depth of market can see your order. 1245
Ok. so all of you are sure that opening price on NYSE and NASDAQ is formed by the exchanges servers and nobody (except the exchange employees) cant see what is happening until Opening Acution starts.. Not even designated MMs ?? Hmmm.. (I bet someone from MMs firm is reading this and rolling on the floor laughing)
I did not say that. I mis-read your question. I thought you were asking what happens to order entered while the pipes are down. You will have to call the NYSE and ask what feeds are available for members and non-members to view before the open. YOu can pay for just about anything these days. http://www.nyxdata.com/Data-Products/NYSE
If you want a clearer picture of the open on NYSE, you need two feeds NYSE open book ultra and NYSE imbalance feed. The open book ultra will give you the continuous limit order book but the imbalance feed will give you the on-open order qty/price/side imbalance, which can be huge. Like if there is 10000 to buy at market on open but there is only 100 shares at top of book on the sell side, then the open price will drift as the imbalance closes. Also the info you posted is for arca, not NYSE, the idea is similar except that NYSE only executes after 9:30am as part of the opening rotation, arca will match you as early as 4am (as you posted). If you were interested in the arca open, the imbalance info is in the arca book xdp feed itself with the book info.
yeah. I found all that in esignal feed for not too much money... tried for a month but didn't find the edge in it for what I do.. so dropped the idea.
