i went short (s&p emini) at the open today and had a buy limit at 1091.00 and a stop at 1100. i got filled on the 1091.00 buy limit and I left and forgot to cancel my 1100.00. i was gone for three hours and came back and saw my stop still on my screen and had the worst feeling in my stomach. my stop was missed my 25 cents. it the mental mistakes that really kill traders and I just about made one.
.. mistakes happen..
