The reason why the long-short ratio of futures is not 1 is that there is a certain proportional relationship between the trading volume and the position of futures. If there are multiple transactions at the same time, it means that the strength contrast between buyers and sellers has changed. In addition, if many are empty, the ratio will not be 1. According to the relevant information, once there is a market, whether it is a cow or a bear, the list you have been holding at this price will become a cow or a bear, but obviously the ratio will not be 1.
