The post-K-line chart is introduced into the stock market and futures market because of its ingenious and unique drawing method. The drawing method of K-line chart in stock market and futures market includes four data: opening price, highest price, lowest price and closing price.

K-line is a columnar line with hatching and entity. The hatching part above the entity is called the upper hatching and the lower hatching. Entities are divided into positive and negative lines. (Shaded lines represent the highest and lowest prices of the day's transactions, and entities represent the opening and closing prices of the day. Among them, the positive lines are usually represented by red, white columns or black boxes, and the common negative lines are represented by green, black or blue solid columns. In addition to the above situation, when the "crosshair" is seen by us, the solid part is converted into a line. In fact, the meaning of the crosshair is very simple, that is, the closing price of the day is the opening price.
