Just letting you guys know that stop doesn't work, at least for me. I have entered a GTC buy stop to add to my Euro futures position, the price was touch twice, the second time the price zoom through it, but the order was not execute. I closed out my position since I don't trust it handling my order any more. I am really disappointed on this. Thought I am going to give some business to IB, guess I will move to some where else.
