K-line is a candle-shaped column line, from which we can see the position of opening price, highest price, high and low price and closing price. The highest and lowest prices are the highest or lowest points of the column line. When the opening price is lower than the closing price, this line is red (positive line), and the low point of the solid line is the opening price and the high point is the closing price. When the opening price is higher than the closing price, this line is green (or blue) (negative line), the low point of the solid part is the closing price, and the high point is the opening price.

When the opening price and closing price are the same, this line is white (cross star), and the intersection is the opening price and closing price. The thick column between the opening price and closing price is called entity, the thin line above the entity is called upper shadow line, and the thin line below the entity is called lower shadow line. K-line also includes xiaoyangxing, xiaoyinxing, xiaoyangxian, xiaoyinxian, xiayingxian, shangyingxian, Toutoubroken yangxian, bald yangxian, shangyingxian, barefoot yangxian, barefoot yinxian and so on.

Generally speaking, we can judge the length of trading time from the type of K-line. For example, the bald and barefoot Dayang line indicates a strong rise. A one-day reversal of a sky-high shooting star has killed countless people. However, it should be noted that when using the K-line chart, the significance of a single K-line is not great. After a period of operation, the stock price forms some special regions or forms on the chart, and different forms show different meanings.

K-line charts are usually divided into daily K-line charts, weekly K-line charts, monthly K-line charts, quarterly K-line charts and annual K-line charts. Usually use the daily K-line chart at most. The lines in the daily K-line chart have moving averages of 5 days, 10 days, 20 days, 30 days and 60 days, which are displayed in white, yellow, purple, green and blue respectively, and the parameters and colors of each line can be changed. From the moving average, we can see the running trend of stocks. The trend in the stock market is the overall running direction of the continuous combination of stock K-lines.

The stock is dynamic. Although it is dynamic every day, the K-line chart of that day will be added and become a part of the K-line chart. After the stock closes every day, the opening, closing, highest and lowest of the day will form a K-line chart, and the daily K-line chart will be combined to form a K-line chart. The daily opening price, closing price, highest price and lowest price are a K-line, with red indicating the day's rise and green indicating the day's decline. When multiple K-lines are combined together, the trend of the stock for a period of time is formed.
