I had several sell stops in the YM right before the Leading Indicators and Philly Fed release at 10am. I was not long at the time - but I wanted to trade the downside momo if the numbers were bad. I was using booktrader. YM traded thru my stops without the stops executing. So I was thinking maybe I'll get a delayed execution - still nothing. So then I cancelled all orders, and the still live stop orders get canceled. Just to be sure I wasn't short - I logged out and then logged back in and I still didn't see any executions. Has anyone had this experience before? This is scary. What if I was long a ton of contracts and the market dropped 100 points?
