Quote from pretzel:
This is what happened:
1. I have an active sell limit at 978.25
2. the market moves past 978.25
3. I dont have any indication on the TWS that my order was filled
4. I thought my computer or TWS has a glitch
5. I cancelled the order
6. Sold another one at market.
7. My position says 0
8. The canceled order was stuck all the time - contract is 0 but the line did not disappear
9. I got a phone call from IB saying I have a sell at 978.25 which was not reported ( 2 hours after the fill)
10. The fill was added to my TWS another hour later

You knew, or should have known something was up. This can and does happen w/ any broker. Count it tuition and be the wiser next time.
