Quote from traderNik:
I have to believe that if a trader knows he's in a mistaken position, it's his responsibility to get out now and ask questions later. If it turns out that the OP could have gotten out completely and decided to try to get cute with the position, he is going to be out of luck with IB. However, as RAY points out, how does IB prove that the trader was aware of the position just because he is logged in. Does TWS auto-log screen toggling? No way...
It will also be very interesting to see what the OP says about the idea that the whole problem was caused by a double click on order entry. Expensive fat fingers. There's gotta be a mouse setting that mitigates the risk of that kind of thing. Link to trading-optimized mice, anyone?
As long as I've been in this business, it's always been the correct practice to immediately close out errors. You don't play the market with them.
Likewise, I'd say it's the traders responsibility to BE aware of the position when he logs in. In other words, you just don't log in and stare idly your first screen. How about open up your account page, check your balance, your positions, etc etc. I do that every time I log in, AND I do it just before I log out to make sure something isn't sitting there I don't want.
I think there is a proper expectation that traders are business-like and responsible with their accounts. Certainly, IB shouldn't be exposed to market risk just because a trader fails to check out his account on a timely basis.
