The essence of futures is to sign long-term contracts with others to buy and sell goods (or stock indexes, foreign exchange, interest rates) in order to achieve the purpose of maintaining value or making money.

If you think the futures price will go up, go long (buy and open positions), go up (sell) and close positions, and earn: price difference = close positions-open positions.

If you think the futures price will fall, short (sell the position), fall (buy) and close the position, and earn: price difference = opening price-closing price.

Since it is a contract, there must be an opponent, so as long as there is a transaction, the buyer and the seller must be equal. There will be no phenomenon that the number of short positions (positions) is greater than that of long positions (positions) or that the number of long positions (positions) is greater than that of short positions (positions).

If the short position is greater than the long position, the price will fall;

The bulls are stronger than the bears, and the price will keep rising until it stops falling (or several boards).
