If you are not trusting your "system," then it is likely not producing consistent positive results, otherwise if something is working, there would be no temptation to tweak it when your green trades are consistently outperforming any red ones. Emotion is the only reason traders lose money, so yes, when you have things set in place, according to what consistently works, get up and walk away when you start second guessing. Play the percentages, manage risk, protect capital, and just keep in mind that technicals don't move stocks, humans do. The market is 100% manipulated 100% of the time, by humans and their immediate intentions. It's MM's, big money, and news that move stocks, up or down. Happy trades!

In order not to tilt or rage every time I lose the position, I personally gave myself a word before commenced trading. I promised myself to calm down every time I am about to rage because of the mistake. Otherwise, I promised to leave trading forever. It's difficult for those can't keep words, but actually this is the strategy I comply with and it helps me to survive on the market. Sometimes I hit a punching bag and nerves calm down. I also tried to practice meditation and it really helped me to calm down quickly without any anxiety or nervousness after losing the position. The last advice - always comply with risk management strategy, and never try to boil the ocean.
