K line is also called Yin and Yang line, bar line, red and black line or candle line. After the stock price has been trading for a period of time, a special area or form will be formed on the chart. Different forms show different meanings. The K-line chart originated from the Tokugawa shogunate period in Japan and was used by merchants in the Japanese rice market to record the market conditions and price fluctuations of the rice market. It was later introduced to the stock market and futures market because of its delicate and unique marking method. [1] Through the K-line chart, the market conditions of each day or a certain period can be completely recorded. The three K-line combinations of insertion line, holding line and positive stimulus line are the most common classic bottoming forms.
