K-line chart (CandlestickCharts) is also called candle chart, Japanese line, Yin and Yang line, bar line, red and black line, etc. The commonly used term is "K line".

Because the expression of K-line chart is intuitive and easy to understand, K-line chart analysis has also become an important tool and means of technical analysis. The K-line chart originated 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. At present, this kind of chart analysis method is particularly popular in my country and even in Southeast Asia. Because the shape of the chart drawn by this method is quite like a candle, and these candles are black and white, it is also called a Yin and Yang line chart. Through the K-line chart, we can completely record the market performance of each day or a certain period.
