Very simple. Even websites like Hexun have a position inquiry system that can query the position cost of a certain company's seats. So if you have a large amount of money in a certain position, you don't want others to know this, especially when you have to open a position in a very favorable position. Because there are some big funds that specialize in sniping. I just want to see in the position system that if you only have long positions, some people will keep going down until you can't be seen in the position report (you have been closed), and then go up again. Moving positions also has this purpose. When you make more profits, you can retreat quickly and then secretly start over again with a different identity.

In addition, there are spot seats for long-term positions. Since it is a long-term position, it will naturally have to be changed later in the delivery month. At this time, the order for the delivery month is also closed, and a new position is opened for the far month in the account opening company. It is difficult for an opponent to keep track of you by changing seats like this. Even if you follow the above, the opponent he faces is not you alone, but all the company's funds in the same direction as you, so you are much safer.
