The low closing date in futures refers to the lowest price, that is, the lowest point in a period of time or history. Futures close at 3 o'clock every day, and the closing price is just the low point. If you want to do a good job in futures, you can't operate frequently, wait for opportunities, just do ten points every day, analyze the market trend by integrating the bollinger band and the time-sharing line, and then place orders steadily.
