how does IB's margin calculations work? just as an example... lets say i go on margin (for forex) 4 times in a single day (buy, then sell all) each time borrowing $500,000 USD. do they charge a margin fee according to the number of hours i borrowed the $500,000? Ooorrr... do they charge "per day" incuring a charge as if i were in it for the full day? further, if they do charge per day, would i incur a "per day" charge for each of the 4 times i borrowed? or would i only incur one charge, since all the trades were made in the same day and did not exceed $500,000? thanks for your help! (yes, i'm new...)
I'm an IB client. I don't trade FOREX but I'm rather certain that if you are flat at the start and end of the day there is no interest charged or paid. You are day trading and that is the way it works for stocks and futures. One caveat. Find out what time the FOREX day ends. Jack
