I want to look at the trend of the external market and predict that the approximate opening price of the domestic futures market is based on the domestic closing price. Remember this price every time. The closing prices of foreign countries on the same day and the trend of Europe and the United States after the closing of Asia are for reference only; I predict the opening price of the day completely based on the domestic closing price 15 and the opening price of the next day. This is more accurate, but recently I found that the external market often waits there after the opening and does not move until after 8: 55. Sometimes it is often a few minutes before and after 9 o'clock;
