Somedude, Opt789 is absolutely correct if the situation is exactly as you describe. IB must make you whole. The fine print will not protect them from a glitch in their software in this instance. This is not a case were the damages you suffered were beyond their control. You probably signed an arbitration agreement when you opened your account. You might have no choice but to get an attorney involved, but try to avoid that. Follow Opt789's advice. And please be persistent. Start with phone calls, but if that doesn't very promptly lead to a satisfactory resolution, put every subsequent action in writing and keep careful records. And please let us all know how this turns out. If IB gives you the run around we want to know that. The right thing for them to do is apologize and correct your account balance.
This brings up a related point. It seems when i opened my current account there was a footnote (small type!) connected to the arbitration agreement stating that I was not required to sign the agreement. I don't think I did as a matter of fact. Does anyone know if SEC regs do not permit brokers to force clients to agree to arbitration as a condition of opening an account? If so, I would think it is better not to sign these agreements, as one could always go to arbitration in any case.
