This time I failed again! To summarize
When making trades, we must firmly believe in our own judgment and not be swayed by others. It's best to avoid looking at the market too much; the more you watch, the more you hear this person is buying and that person is selling, which can lead to an unstable goal. If you close a short position and switch to long, the market might keep dropping. If you close a long position and switch to short, the market might keep rising. It's important to reasonably control your position size and slightly widen your stop-loss level to allow for market fluctuations. If the market breaks down or rises, you must promptly cut losses. Look less at the orders in the market; most are just calls for someone to take over. Let's encourage each other!
