Candle chart, also known as K-line chart, shows the same information as bar chart, but it is more beautiful and vivid. The candle chart is drawn according to the opening price, the highest price, the lowest price and the closing price of each analysis period. Take the daily K-line as an example, first determine the opening price and closing price, and draw the part between them into a rectangular entity. If the closing price is higher than the opening price, the K line is called the positive line, which is represented by a hollow entity. On the contrary, it is called a negative line and is represented by a black entity or a white entity.
