sorry for asking a dumb question here but i have searched the site and ib's site as well but i still dont know how much initial deposit is required to trade the sp mini and the nasdaq mini. Ib's site has the intraday initial and overnight initial, so which one do i go by to figure out how much money i need to open the act with? i know the act should be funded w more than just the initial to be able to sustain act swings, but still which initial margin requirement do i look at??? thnx guys.
