Only Shanghai Stock Exchange Index (f3) and Shenzhen Stock Exchange Index (f4) have yellow lines. The 180 index and the 50 index are not. The yellow line of the index is different from the yellow line of the stock. The white line of the market is weighted to consider the influence of the stock circulation on the stock index, commonly known as the index. The yellow line does not consider circulation. When the relationship between the two lines rises, it shows that the large-cap stocks have a good upward momentum. Yellow characters on a white background indicate that small-cap stocks are rising well. During the decline, Huang Xiabai said that large-cap stocks fell sharply, and Bai Xiahuang said that small-cap stocks fell sharply. The white line of individual stocks is the stock price. The yellow line is the average price of the day.
