One step forward two steps back

Costly exercise in bad trading running against uptrend. Trouble was also that every position was full one, so I blow all money management reasoning. Around 11.25 I had profit of 5 pips times two positions but I didn't take it. I wanted more, I really get up that morning on wrong foot. About minute before my exit I was red just for 12 pips x4 positions. Than gbp/usd took of like crazy and every second was costly. Than it looked like a fake spike up and I shorted again with with full 4 positions and lost again more.
-50
-35
-23
-13
-9 x 4 = -36

-157






In hindsight if reversed my positions would be very nice. It's so easy to fight the trend and so hard to just let yourself with the flow.
