To be honest, I used to have the habit of using stop loss, but I was hurt and brainwashed, and I fantasized about a violent bull market every day. So no matter what I bought later, I abandoned the habit I had always developed. As a result, I am now a stuck person like everyone else, and I feel sad and uncomfortable every day. When I get out of the trap or wait for short-term opportunities, I will definitely use stop loss, because stop loss is the lifeline and a habit of saving life. In short, if you have green mountains, you will not be afraid of running out of firewood.
