For decades, mathematicians have been trying to predict the stock market mathematically. Therefore, various indicators and algorithms, such as MACD, KDJ and RSI, have been introduced.

After the founding of New China, the history of China stock market is relatively short. There are some similarities and some particularities between China stock market and foreign stock markets. For example, the split share structure is a characteristic of China. Therefore, it will definitely be more difficult to forecast the China stock market. But I believe that many professional or amateur mathematicians are also studying and forecasting the China stock market.

However, perhaps because of my lack of knowledge, I haven't heard of any expert who is a recognized authority in this field. If anyone knows, you can recommend it, hee hee.
