short near money calls/puts in the afternoon of expiration day. Sometimes within last 30 minutes. Gotta to watch and be ready to buy back - take loss immediately. The idea is your short opts expired worthless. One gotcha, if the company whose opt you are shorting has earning or big news next monday pre-market, your opt may get exercised even if out-of-money if you leave them on the table over the weekend. Happened to me. I shorted BofA call opts, it finished 0.01 of out money. Think I got it made ? Nooo, turns out next monday pre-mkt BofA had big earning and it was pre-mkt. I got ding big time! Out side of that exception I have been profitable 8 out of 10 expirations.
