Expiration time

The time of day by which all exercise notices must be received on the expiration date. Technically, the expiration time is currently 5:00PM on the expiration date, but public holders of option contracts must indicate their desire to exercise no later than 5:30PM on the business day preceding the expiration date. The times are Eastern Time. See also Expiration Date.

This is a definition, not a recommendation. Options carry risk and can expire worthless. See how the desk actually trades at TrueTrader.
