In the trading process, there is a saying: follow the trend. If you can't beat them, join them. Never be stubborn. The market can switch between bullish and bearish very quickly. Right now, it's neither a bear market nor a bull market—it's a "monkey market" with lots of ups and downs. Setting stop-losses is really necessary. If your position gets stopped out, take a break; don't get emotional. After 9:00 every day, go long.
