I dont really believe this story.
Sure, SureTrader looked suspicious being offshore, and I wouldn’t send them my money. But many people used them for years and were able to trade and transfer money in and out. While the SEC also investigated them many times and never found outright fraud.
And many of the SEC rules still apply to international firms offering investments to Americans (that’s why we’re not permitted to trade international options), so the SEC would’ve found many wrongdoings if they didn’t even send your orders to exchanges. And the SEC was very interested in them and did try to find reasons to disallow them from doing business with Americans, or shut them down.
Anyway, here is another story on the closing of SureTrader that seems less sensational and more in line with what I’d believe:

(Btw, how many people here on ET complained that SureTrader stole their money and wouldn’t allow them to withdraw? This forum often gets stray visitors who complain about whatever broker they’ve dealt with.)
