Hello, my friend. Actually, it makes no difference. Generally the difference is 1 to 2%. The lower margin is only a little less than the first margin payment of your transaction. It turns out that 65,438+00,000 yuan can be used for 5 transactions, but because the margin is a little high, only 4 transactions can be made. This is the reason, but considering that risk control futures investment cannot be traded in Man Cang, the impact on customers can be ignored.
