The K-line is also called the candle map, which is drawn from the opening price, the highest price, the lowest price and the closing price of each trading day (or every analysis cycle). The K-line structure can be divided into three parts, the upper film line, the lower film line and the middle entity.
The K-line is a columnar line consisting of a shadow line and an entity. The middle rectangle is called entity, and the thin line on the top of the image line is called the upper shadow line, and the lower part is called the lower shadow line. The substance is divided into the sun line and the shade line.
The K-line shows the strength of the buyers and sellers and the transformation process and actual results.
When the closing price is higher than the opening price, the entity part is usually painted red or blank, called "Yang line".
When the closing price is lower than the opening price, the entity part is usually painted green or black, called the "Yin line".
