Regarding the issue of the timing when I place orders, I usually do it at midnight. It's because I am a night owl and my mind is clearer and more agile at that time. At the same time, I feel that you are all asleep at midnight, which can reduce the uncomfortable feeling of being watched after placing orders. The fluctuations at night are also larger. So during the day, I usually sleep and watch TV. Unless the market is very good, I generally only glance at the market during the day. Even if there's a good opportunity, I don't want to take action because I'm afraid of feeling tired after placing orders.
