I know when I opened a trading account, and I have a few of them, they all had a form that I had to sign basically saying that even though they had an algorithm to help stop you from going over your limit or margin, technology is not perfect and if I am going to trade with them, I have to accept responsibility.Quote from gnome:
OP probably signed arbitration agreement when account opened. No attorney, no lawsuit.... and $700 is too small to mess with beyond begging broker to "make things right".
There is also an agreement that the client bears full responsibility for all online errors. I think he's SOL, unless broker just wants to be "nice".
If you only lost $700, be glad, it could have been a lot worse, if you are daytrading, get used to losing money, I don't think you have much of a chance against the Schwab lawyers.
I would have to ask myself if I really wanted to invest both the time, and money, to fight for $700, and remember, you were the one to put the numbers in, you are somewhat at fault. Just my pennies worth.
