Specifically, hedgers will buy and sell futures contracts with the same quantity and duration at the same time, and then wait until the price fluctuates to earn profits by buying and selling different futures contracts.
The advantage of this strategy is that it can reduce the risk, because the profit and loss earned by the hedger will offset each other, leaving only the net profit or loss. At the same time, hedgers can also make use of market fluctuations to make profits, because when the market price fluctuates, hedgers can get profit opportunities by buying and selling different futures contracts.
