Ok, I'm not a professional; I run a couple million of family money at IB, and that's it. But recently two friends from a foreign country (Australia) asked if I could trade some capital for them, in my main account. They would simply transfer the money to me (as opposed to me running it in an IB account under their name opened in Australia.) Legally, what problems or paperwork might I have? Should I put the money in my pool, which I suspect will create tax headaches for me. Or insist they open IB accounts and give me the right to trade. Are they trying to launder money through me? They don't seem like the type, and the amount were talking about here is a pittance (About 100K AU).
