Hello, I have only traded US markets so far and am mildly interested in trying my strategies out in different markets. Most of my money is tied up in my roth since that was my first trading account. Are there any implications I should be aware of before starting tax wise/commission wise/cash settlement? Right now I just have a margin IRA account. Is it just as simple as applying for foreign market trading, subscribing to the right data feeds and then I can begin buying/selling. Do I have to trade dollars for pounds first before doing a foreign trade for instance? I'd appreciate any advice from someone with any experience. Thank you, Optionsgambler
