I don’t have a story of my own to tell in that regard but what I think make someone that experienced as you said quit trading must have to be something huge that cannot be neglected. As an experience trader, I can’t see any possibility of you leaving trading. If you’re that experienced, you would be profitable already and if you’re already, what could be the reason you want to stop trading. It all falls back to your psychological mindset to be able to hold and be consistent in your trading that will determine you leaving or staying. Over all, what I still think is that if you’ve made up your mind to make that money from trading, you won’t leave no matter what it losses you might have gotten from there.
