Making contracts is like an experienced hunter, always waiting for the prey to appear. When the opportunity arises, one must pull the trigger bravely. Of course, a stop-loss line must always be set. Dharma often says to stop loss! There's no trick to it; it's the secret to surviving in the long run. It sounds simple, but it's hard to achieve. Although there was no damage from a crash earlier, when a quality point came out at 9 PM last night, I didn't pull the trigger. Note this lesson. Keep summarizing and strive to do better next time. Keep it up!
