Yeah you can do that both in the app and think or swim but I recommend think or swim. It's probably the most powerful brokerage app/website you can use for retail. You can set up timed market orders and sell at 3pm or you can do it via OCO bracket orders in think or swim - I recommend the OCO, it's basically a neat flowchart system of various orders attached to an option. It has time as a condition too
Thank you. I’ll do a deep dive on OCO.
