Second time this happened in a week. I have a pending stop/limit order that hits the stop price. The order line drops off my main page, and the order also drops off the pending page. But, no execution. This is scary and frustrating. Called IB both times and they have no response. One more thing. Both of these instances I had orders that had been modified. Is something getting screwed up when I modify? In the past when I transmitted a modified order the status color would hang on light blue, but both these times it went blue immediately, or rather, never really changed that I noticed. Am I modifying the order line wrong? Any comments from users that have experienced this much appreciated.
