I just want a straight answer I have a ticket (or two) with IB asking about intraday margins, specifically when they begin. i'll spare y'all a long story about trying to get a simple answer by asking ... When do they begin? their online info states when 100% margin is in effect but not when intraday margin is in effect. I was told "margin requirements will revert back to the 100% requirement until the opening of normal trading hours the next day" normal trading hours the next day is different for all markets/exchanges? oi!!!
