I've been keeping an eye on IB Canada for a bit now as a potential brokerage to open an account with (my current brokerage is very pricey), and I have a couple of questions regarding currency issues. I know that IB offers a "Universal Account" where you can trade various types of derivatives and securities, and that you also select a base currency for the account. My question is - if I want to trade both CND and US products, is it possible to split up the account in some manner? Aside from currency exchange risk, I understand that it's preferable to denominate a brokerage account in the same currency as the products that you are trading (e.g. $CND if trading Canadian stocks, $USD if trading US stocks), else you end up with fairly significant costs from the constant currency conversions. So if I choose $CND as my base currency for an IB account, and trade some $USD products, is there a way to work around this, or do you end up running two accounts, one with base currency of $CND and other with base currency of $USD? Thanks in advance for any answers, I'm trying to understand how a trader would best handle trading in products with multiple currencies when using IB.
