Every now and then, you may get two executions while changing an order without hitting the "T" letter. But TWS usually reports as two fills.
I'm talking to IB chat online. The person told me "please manage your current position" when I asked "Do I need to liquidate it now?".
I guess they are telling you that if it is showing up as an open position in the TWS you should assume it is going to be your trade and either hold it or liquidate it as if it were a normal open position you initiated.
i think you might be screwed on this, from what you are telling us they are saying. one thing you might want to do is hedge the position by shorting ES, it would have been better if you could have short it, when you noticed all of this happened.
According to IB's log, I entered the order and changed many times and final change was at 10045, then the order "dropped off my screen" (direct quote from IB Help). Hours later IB found the execution and sent me the email. Now, they blame me not reproting to them the order was dropped at the moment. I didn't notice it either. TWS didn't show it as open order at the time and IB system didn't catch the execution either since no report in TWS. They sent me the email hours later.
If you had an open order and it suddenly disappeared from the TWS screen you must assume it is still a working order since you didn't cancel it.
Did you cancel your first long and enter a new long? Or did you change the price of the long and hit transmit again to new price? If you changed the price and hit transmit again, this error shouldn't happen and IB will probably eat their programming mistake. That really sucks, you should have IB figure out what's causing the problem so it never happens again. Have them do an audit trail of your trades in that time period. Maybe def can help you with this issue.
How do we know if an order is still open if TWS does not show so? Many times, TWS rejects orders or we cancel orders and TWS removes them from the order entry grid as we all expect. With this yo-yo login problem, it's hard to notice that an open order is dropped suddenly. I entered another order to cover my short position and TWS showed me that I was flat after that execution. Had TWS showed it as PINK or other information, I would contact them immediately and take necessary action. The system failed and they need to fix that bug.
TWS are you using what java software version are you using what type of computer do you use etc .... let IB know everything .... good luck ....
So you had your original buy order up and then you started to modify the price but before you hit transmit, the original order got filled (before the price change)? If this is what happened, then IB should eat it. Reaching here, but is it possible you have some weird shortcut mapping that would make this change operation trigger a transmit?
