I have sold SPY weekly call option with strike price at $302 which is expired today. at 16:00pm, spy closed at 302.01. however, after 16:00pm, spy traded below $302 and now at $301.45. will my option be assigned?
i think it is quite tricky here. since option buyer has right but not required to exercise the option, it is foolish for call buyer to exercise the spy call at 302. but if the buyer does not inform its broker not to assign, by default all option in the money even of 0.01 will be automatically exercised.
