The rule is that you can't just grind for points; you also need to know how to play the fluctuations. Those who only incur losses every day, such as only losing on transaction fees and only cutting losses, are all targets of the platform's risk control.

Don't say anything like not playing contracts or being banned for not trading; that can't be the reason.
I will post the rules in the comments section, everyone like it so more people can see.
