Has anyone had problems with a stop order with IB. Today afternoon at around 1:30pm I had a stop order to sell 5 NQ at 1379. At 2:11pm I knew I still had the position, for 30 seconds I looked at some other window and when I came back I saw the order got executed at 1381.5, I was pretty surprised at the execution price. But at that time I did not have real time historical chart or time and sales to check whether 1379 was hit. My order execution time was 14:11:33 I came home and verified with time and sales window that around that time the price of NQ never dipped below 1381. I ended up missing the end of the day rally and it potentially cost me 1350 because my target was to get out at 1395. How do they settle these kind of problems. Looks like TWS does not store the history of your orders to figure out why the order got executed.
