From a personal investment point of view, I think the ant order only plays a role in the initial practice, because before the investment system is established, you need to be familiar with the market enough, you need to have a large enough fault tolerance rate, and the first purpose of the ant order at the beginning is the venue practice fee. Wait until you have enough disk feeling, and then try to expand the amount to exercise your mentality, especially the control of personal emotions. The larger the position, the more important the mentality.
