In the total position of futures, bears and bulls are equal, in other words, the strength of bulls and bears should be equal, so futures prices will change.
The amount of stock bought and sold every day is the same, but the price will still fluctuate, except for the ups and downs. The main reason is that although the amount of buying and selling is equal, the intensity is not always the same. Sometimes buying is so powerful that some people can't buy it. At this time, he will pay a higher price, and the price will naturally rise. If you work hard, the price fluctuation will be the opposite of before.
