I have a margin account at IB. The base currency is USD but I want to have more then one currency in the account. I've been told that this is possible by IB but they haven't gotten back to me on this matter when I ask for specifics. I'm thinking of placing basket orders for four different markets in four different currencies. Each market won't exceed 25% of the total portfolio. 1 Has anyone tried this successfully with basket orders? 2 What happens if the order is bigger then the available funds for the currency? The reason for this is to pick four markets where a particular script works well and to reduce risk.
