So many times I wake up and see my money 10%+ down, it's becoming boring to see that, I do not feel any emotions at all. Main reason? Because I also saw it go up 10% as well, much more. This is why I do not worry because I know that even if it's down now, it will go up eventually in the end.
Maybe you've been in the space of longer period of time, and that you've built the emotional pains that may caused it, it's not always easy to withstand the pressure the market downtrend comes with, that's why I always say that traders should've been provide what he can afford to loss.
