Happened again. Order not execute. I checked the setting before I placed these orders. Its a buy stop limit, and the price was hit like 5 times on the minutes chart, and yet, order not execute. I am bless this is an open order, imagine when you depend it on closing your position. Now, I need a recommendation of a futures broker. OEC data is mess up now, so it's own of the questions. In additional, it also mess up my account a little too.
