Of course, we can't assume that all situations will be like this. My personal point of view is that in the process of market trading, the irregular distribution of long and short positions will have a certain impact on the transaction, but most of the impact is beneficial. In the case of favorable long and short positions, the market will be more favorable to bulls, and vice versa. Therefore, the market is beneficial to both long and short positions, but the opposite will also happen. When the distribution of long and short positions is unbalanced, the market will be even more unfavorable to bulls and even bears.
Generally speaking, the long-short distribution is unbalanced, but this situation mostly comes from the contradiction between supply and demand in the market. When bulls and bears are evenly matched, once the contradiction between supply and demand in the market is prominent, bears are in danger of being digested. So the unbalanced distribution of multiple spaces is beneficial. The uneven distribution of long and short positions not only exists in the futures market, in fact, in the real market, there are many stock markets and even bond markets. The irregular distribution of long and short positions in these markets will also have advantages and disadvantages, and accidents will occur if the long and short positions in the market are equal.
For the exchange, the position fee of the exchange is paid at different spreads according to the percentage of the market price. Theoretically, the percentage of each market price is different, but the spread of each market price will not be too big, because futures trading is based on the settlement system of the day, and each market will choose the spread of the market price of the day according to its own situation.
