Thanks for the question. I’m trying to make sure I understand the question. There seems to be 2 topics here.
The first being that you don’t feel you were able to exit I a price that you thought you would. If this is correct, this is a standard topic/question we can address at the meeting.
The second being that you had a limit order “sitting” in the platform for -41.8 and it “later” filled for -40.92. If this is the case, this should not happen and would be a broker issue. In this case I would suggest contacting IB to resolve the issue. A note here however, “IF” you put the limit order in “and” it filled immediately, then I’d be relatively certain that you put the order in incorrectly. This is extremely easy to do with the IB platform.
