The launch of futures only means that futures have one more direction choice than stocks and can be short. The specific operations are divided into two situations: long and short. Long: judging that the subsequent market will rise, you can buy futures contracts at a low price, wait for the price to rise to the target price, sell and close the position, and make money in the middle; Short selling: judging that the subsequent market will fall, you can sell the futures contract at a high level first, and then buy and close the position at a low price after the price falls, and the profit is also the difference.
