Extended information:

Yin line: In the securities market, it refers to the K line where the opening price is higher than the closing price. The K-line chart is generally marked with light blue, indicating that the stock is falling. When the closing price is lower than the opening price, that is, the stock price trend shows a downward trend, the K line in this case is called a negative line.

Yang line: In the securities market, it refers to the K line whose closing price is higher than the opening price. The red line marked on the K-line chart indicates the rising trend. The thin line at the top of the K line is called the upper shadow line, the thick line in the middle is the entity, and the thin line below is the lower shadow line. When the closing price is higher than the opening price, that is, the stock price trend is upward, we call the K line in this case a Yang line, and the entity in the middle is indicated by blank or red.

Taking the Yang line as an example, the part between the highest and closing prices is called the "upper shadow", the part between the opening price and the closing price is called the "entity", and the part between the opening price and the lowest price is called the "upper shadow". Make "lower shadow".

Drawing method:

First find the highest and lowest price of the day or a certain period, and connect them vertically into a straight line; then find the opening price of the day or a certain period and the closing price, connecting these two prices into a long and narrow rectangular cylinder.

If the closing price of the day or a certain period is higher than the opening price (that is, opening low and closing high), we will display it in red, or leave a blank space on the column. This column is called It's called "yang line".

If the closing price of the day or a certain period is lower than the opening price (that is, opening high and closing low), we will express it in blue, or we will paint the live column black. This column is " Yinxian".
