Does anybody have any experience with IB, where stop price triggered and fill way above market price but the fill price does not show on the chart? I trade DIA, and set stop at 110.80 but was excuted at 110.87, at that time the market price was 110.80/110.81, but does not show on the chart. I ask IB for an explaination, and they first said my fill price was at 110.78, then i reponded saying it is impossible, then they say they overlooked, and will not make adjustment to the error. They do not admit the error, and make no effort to correct it. Is price sometime don't show on the chart? if it is, then is not their fault.
