Stock index futures don't mean how many points will explode. It depends on how much money you have. For example, you have 500,000 yuan in it, the price of the first-hand stock index futures is about 6.5438+0.5 million yuan, and you still have 350,000 yuan available. Every point of stock index futures is 300 yuan, so if the stock index futures fall more than 654.38+0. 1.000 points, you will explode, which means your availability.
