1. First choose an optimistic future.
2. If you think that the futures price will rise, buy it immediately and sell it when you close your position, you can earn the rising price difference.
3. If you think the futures price will fall, sell the futures at the current price, and then buy it after it falls, so as to get the profit of the difference when the price falls.
At present, the China stock market only has a multi-mechanism and can only buy before selling. Therefore, it is best to choose futures with rising prices to operate, so as to make money in the rising futures market.
