Quote from EnglishTeach:
Still need to clear up a question. I could have sworn the broker told me on the phone that the $300 margins apply to after hours (positions opened before 8:30 and after 3:30 Central), but in the fine print I think it says that exchange minimums apply for those times. It may be a question of when the contract is opened or it it's held through 3:15 or not.
Thanks for responding.
