Hi all, I have an account in EUR denomination with IB and I want to daytrade US stocks and futures. Hope someone can answer my two simple questions: 1. Which of the options a,b below is the least expensive way to daytrade USD denominated instruments with a EUR account? a) convert a chunk of the account into USD. I'd have to pay the bid/ask only once at conversion (plus there is a small commission), but I would incur in currency risk. b) keep the account in EUR and incur in the EUR/USD bid-ask spread at every transaction ( it is not clear to me from IB's website if they apply commissions in this case). 2. If I have, say, 20k EUR and 30k USD in the account, do I get hit twice by the zero-interest threshold? In other words, is it correct that I will not be earning interest neither on the first 8k EUR nor on the first 10k USD? Thanks.
