I don't personally know of online firms with fraud protection in which clients lost money due to the actions of the broker's employees (which was what my post was addressing). But in response to your broader question, there's a thread here http://elitetrader.com/vb/showthread.php?s=&threadid=90860 about someone who says he's getting no response from E*Trade about unauthorized transactions.Quote from GTC:
I disagree. Do you happen to have known or heard any examples in which the brokerage firms that have fraud protection did not restore its deserving clients' accounts after the fraud occurrence?
Personally, I've been a victim of unauthorized trades by a full-service broker. I promptly reported the problem to the firm's management and to the clearing firm. I got no money back. My case wasn't isolated; the broker and many of his coworkers went to jail.
