1, the opening price of the day is based on the trend of foreign countries the day before, and all investors participating in the bidding match the bidding, which is not arbitrary!

2, this relationship is not very big, today's price is just higher or lower than yesterday's closing price!

3. The center line is the settlement price of the day and the horizontal line of the next day. This price is the average price of all the volume and amount of the day! ? If you open lower and go higher the next day, as long as the price is still below this line, it will fall relative to the previous day!

4. Is there a picture below? Let's wait and see.
