If you had the expiry (sually a month) then the answer is no - As long as it is a partial sell and you leave the remainder to sell (You can amend the sell by the way), you pay the brokerage ONCE and the remainder will trade at $0 brokerage.
If the order expires TODAY and only a partial sale has gone through - then the remainding stock will need to be placed again at an additional brokerage.
"They were sold on default expiry." > What is the defalt date?
