I trade ES with IB and I keep getting my stop order triggered AND executed at price OUTSIDE of the reported trading range. Anyone with the same experience? Today for example, I had ESZ9 stop sell at 1059.25 at 10 minutes before 4PM ET. It traded down 1059.50 before ramping to 1062 but IB says my stop was executed at 1059.25! This has happened many times. WTF?
