Futures are T+0 transactions and can be bought and sold at any time during the trading period. Futures prices change every day, sometimes even by a large margin.

There are mainly two kinds of people who participate in futures trading. One kind is speculators (the purpose of buying and selling futures is only to earn the price difference of futures through trading). ); The other category is hedgers (such as soybean seed value enterprises and soybean processing enterprises, who can avoid the risks caused by soybean price changes by buying and selling soybean contracts).

Therefore, futures trading is gambling. Because transactions are frequent, as long as there is buying and selling, there will be gains and losses.
