When I open trades, I like to set and forget about them, only checking on them once in a while to find out if I can trail my SL according to my trading plan. The way I remove emotions is simply by distracting myself with other activities and I found that to be effective. My advice is when you open a trade, and after setting your stops, go and do other things; go work out, play video games, go cook something good, do anything else you like that would keep you away from the charts. This way I am able to remove my emotions, "sit on my hands" and improve my discipline and also prevent myself from doing a mistake; I let my trades work out themselves and don't try to micro manage them.
