What this brother said is so right. In fact, many times when I've lost a lot of money, it's because I didn't close my profitable positions completely and ended up averaging down after being stuck, leading to losses. Actually, it's best to set a break-even position. Last night, I incurred losses because I didn't close my small profitable position and continued to add to my position in the opposite direction. I really need to pay attention going forward.
After actually closing my position, my heart really felt calm. Looking at such a poor market, I felt nothing. Today, I continued to enjoy half a jin of Yulin specialties and went out for a walk, which improved my mood a lot. Although I wasted a whole day yesterday and lost 1100 in oil, when I calculate it, it doesn't really hurt my foundation. I'll just take it as a lesson for myself.
I hope to find my own problems from each trading failure and be able to correct them. It's really hard to make money, but losing money is really easy. Let's encourage each other, my friends.
