I used to have an account there and all U.S. clients got the boot late last year. In fact, not only didn they refuse to take new accounts, but they made everyone who did have an account with them close their account by the end of January 2010. So, they no longer service U.S. clients. Pick another winner.
I moved to GO Markets, but find that they are now no longer accepting new U.S. corporate/partnership accounts.
I fear it is only a matter of time before many, many more offshore brokers choose to no longer do business with Americans.
