The mainstream market software includes: Master Boyi, Wenhua Finance, Fuyuan, etc.
The mainstream trading software includes Hang Seng, Kingsoft, Trading Pioneer (TB), Yisheng and so on.
As for which one is useful, it depends on the habits of investors. Everyone's standards are different. You can download it all and try it for a while before making a decision. Personally, I prefer to use Mandarin Finance and Master Boyi. Master Boyi's interface is simple, but its functions are much less than those of Wenhua Finance. Personally, I prefer Hang Seng's interface to trading software. Trading pioneers are mainly used by programming enthusiasts, and most of Yisheng's users are speculators.
