The historical K-line chart of K-line (Candlestick Charts) is also called candle chart, Japanese line, Yin-Yang line, bar line, etc. The commonly used term is "K-line" , originated from the rice market trading in Japan during the Tokugawa Shogunate era (1603-1867) in the 18th century, and is used to calculate the daily rise and fall of rice prices. Because of its unique marking method, people introduced it into the analysis of stock market price trends. After more than 300 years of development, it has been widely used in stocks, futures, foreign exchange, options and other securities markets.

The basic composition of the K-line is a columnar line, which is composed of shadow lines and entities. The part of the shadow above the entity is called the upper shadow, and the part below it is called the lower shadow. The entity is divided into positive line and negative line. The shadow line indicates the highest and lowest trading price of the day, while the body indicates the opening and closing price of the day.

K-line classification: According to the calculation period of K-line, it can be divided into daily K-line, weekly K-line, monthly K-line and annual K-line. The weekly K-line refers to the K-line chart drawn based on Monday's opening price, Friday's closing price, the highest price for the whole week and the lowest price for the whole week.
