For the futures market, the number of short positions and long positions is always the same. Neither side will have extra hands! So you can see an "open position" in the futures market. This number will increase or decrease for a period of time. Today is 10000 lots, and tomorrow it may become zero lots. If you write an empty bill, someone will write more than one bill. No one will open more than one order, and neither will your empty order. Then the daily limit will drop. The so-called "everyone is bearish" always has a degree, right? Didn't everyone expect that it would fall to 2000 points in May? Therefore, on a certain index, "everyone is bearish", then it will fall. Until there is disagreement. For example, this morning, the main contract of stock index futures 1005, the two sides disagreed around 2380 points. Everyone can open a position. Also opened an empty list! In the afternoon, something is wrong, just like you said, "everyone is bearish." At this time, you want to sell 2350 points, and no one wants it. You have to go to 2320 or 2300 to be free. The market price went on like this. You earn what's empty in front. You earn long money. It's not like stocks. In the stock market, everyone may make money or lose money. What you earn in the futures market is long money, or a long and short bet on whether the stock market will go up or down in the future.
