Hi all, Firstly, yes ive tryed customer service both online & on the phone but they have difficulty in understanding my question. Here goes; I live in Australia and have a AUD dollar IB a/c, i'm wanting to trade US stocks and therefore considering changing my base currency to USD. Now, would I have to buy the AUD/USD fx pair to hedge my currency exposure or when I change my base currency to USD does that simply create a sub-account within my AUD de-nominated a/c therefore taking out the need for me to put on a hedge? Any help is much appreciated. Thanks.
