When you finished great or (especially) bad trade you should go rest/beer/friends/whores/family. Anything but not trade. Stay away from trade. When emotions will calm, start to think what next.
Because in the end that is what I did to improve. I would turn off my computer and go read a book in the sun.
Really starting to appreciate my profits instead of being in such a hurry to make more all the time.
Realizing there will be plenty of great opportunities down the road brought me happy times.
nothing like profit "down" the road.
