I would say first of all, accept that this is normal at this stage of your journey. Not a weakness. Secondly, I don’t think it will ever go away completely. The more consistent you get, the more red days irritate you. Because you go from “not knowing any better”, to “WTF, I know I am better than that.” Solution : as you get more consistent (with lots of resilience), you will realize that you are able to recoup red days fairly easily(assuming you are trading “correctly”). So you go from “one step forward, two steps back” to “three steps forward, one step back” to “that was one of those freak days, oh well” Good luck.
I you have a written trading plan you can keep in mind the old saw, “Can I trade 100% Inline With My Plan And Rules On The Next Trade I Take?”
