My original point was that it was TLTC because it was probably marketable at the time that the cancel was sent, regardless of whether it was before or after 16:00.
Well, its kind of hard to tell isnt it, since if it wasnt marketable it would not have executed. I doubt they can determine marketability at 4pm exactly, else they would not print the close 1 minute and 30 seonds later.
Was the limit order marketable at any time between placing it and 16:00? What was the limit and what was the quote?
What time does the NYSE print the closing price for stocks? Is it 4.15pm ET? If so, is there a reason why my requests to cancel NYSE orders are not being accepted now?
The specialist closes a stock when it prints imbalance/close trades. It can be any time after 4:00pm. I saw some close prints well after 4:15pm NYSE will reject any FIX messages that comes after 4:00pm with 58=REJ - MARKET CLOSED
Thanks for your reply speculatus. Is there a cutoff time for NYSE imbalance/close trades being finalised? Using a silly example to demonstrate my point, is there anything stopping a closing price being printed after 8pm?
