When do listed equity options cease trading?

Listed equity options cease trading at 4:00 p.m. Eastern Time on the expiration date. This is important for traders and investors to know because it marks the end of transactions for that particular options contract. After this time, no new trades can be executed, although the options can still be exercised or settled if held until expiration. Understanding the trading hours and expiration times helps investors plan their strategies effectively, ensuring they take action before the cut-off time. Choosing the correct time frame for trading options is crucial, as missing the deadline can result in lost opportunities.
