I had a long position open in ES 09-13 in SuperDOM. Currently there was an open sell limit order at 1670.50. OCO was active. I decided to add a stop at 1668 using Ctrl+Alt+L-click which I have successfully done before. A sell limit order for 1668 was executed instead which got filled immediately without the usual confirmation screen, exiting my position at 1669.50.
This is most discomfiting as I've never had this happen to me before. I don't know if you can shed any light on the matter.
