Anyone else getting horribly bad fills at the open, when buying/shorting on IB? If I buy , I will get the filled at the high of the 1 min bar from 6:30 to 6:31, and if I short, I will get the low of that same bar. 5/5 today. Is this normal? I have been getting way better fills with scottrade. 2/2, I got a resonable, in the middle price price today. Is this because I submitted a regular limit order to buy/sell instead of using the "OPG" command.
