Extended data
In the spot market and futures market, the same commodity is bought and sold at the same time in the same quantity but in the opposite direction, that is, the same quantity of futures is sold or bought in the futures market while buying or selling the real thing.
After a period of time, when the price changes make the profit and loss in spot trading even, the losses in futures trading can be offset or compensated. So as to establish a hedging mechanism between "now" and "period" and between near and far, and minimize the price risk.
The trends of spot and futures markets converge (under normal market conditions). Because these two markets are affected by the same relationship between supply and demand, prices rise and fall together. However, due to the opposite operation of these two markets, the profit and loss are also opposite, and the profit of the futures market can make up for the loss of the spot market.
