I had moved a stop up and submitted two market orders too sell WMB at matrket after hours.
These were filled whilst away both of them putting me short. I was sold out at low whereafter share recovered where I had to be back square for a loss on the way down and UP.
Order entry and incidental mistakes have been plentiful. They have cost me the difference between good growth and a net down position.
I have been in numerous upside break outs but are net down at present!
Trade placement is requiring more attention.
Order verification and clearing of duplicates is essential.
Especially when a number of trades are in play.
