NYSE cancel at close question

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?
