Quote from indahook:
true..but if his actual execution was ten seconds after the close he can bust it. To really know he must get the branch sequence number and time from the broker who executed.
I respectfully dissent...
e.g.
Looking at IBM time and sales for yesterday you can clearly see that stock closed 16:01:04 65,900 shares 89.12
NYSE printed 60,000 shares of stock between 16:00 and the close. All those trades stand.
The broker surely has a branch seq. number representing the trade, but I do not know of any rule that forces him to disclose it to the customer.
