Hello, the handling fee of the stock index is around 1000. Because the multiplier of the stock index is 300, the value of a fluctuation point is 60 yuan.

According to the current stock index price of 3794, the handling fee of flat warehouse is about 1 100 yuan, and the unilateral opening and closing of warehouse is about 28 yuan. In other words, Ping Jin needs to earn nearly 20 fluctuation points to make a profit, and it needs to close its position overnight for more than one fluctuation point to make a profit.

It can be calculated from the above that the handling fee in Ping Jin is 40 times that of opening and closing positions. In order to avoid the high handling fee of closing positions, investors are advised to open positions in the form of reverse locking and then close positions bilaterally on the next trading day.
