This is a question for Yanks trading abroad. I understand that as a Yank, I pay US taxes no matter where I live, but it is an important distinction as to whether the income is US sourced or foreign sourced. So I am not sure what applies. The trading would be done abroad (the actual "work"), but I'd be using US brokers and exchanges.
In case anyone is curious as to why I care. There is one place on the planet where Americans can structure their income to pay lower rates, and still keep their US citizenship. The US Virgin Islands. This is because you pay the VI and not the IRS. Generally, income tax rates are the same, but not with passive income. Passive income, if Virgin Island sourced, is only taxed at 10 percent. There are actually several hedge funds located there for tax reasons.
