K-line chart has many other names, such as candle chart, daily line, yin-yang line and so on. We often call it K-line. Its original purpose is to calculate the daily trend of rice price. Later, it can also be used in stock, futures, options and other securities markets.

A columnar bar line composed of shadow lines and entities is called K-line. The hatching part above the entity is called the upper hatching and the lower hatching. Entities are divided into positive and negative lines.

Ps: Shaded lines represent the highest and lowest prices of the day's transactions, and entities represent the opening and closing prices of the day.

Among them, red, white columns or black box hollows can be used to represent the positive line, while green, black or blue solid columns can be selected to represent the negative line. When the "cross line" is seen by us, we can think that a line is the shape of the changed solid part.

In fact, the meaning of crosshairs is very simple. The crosshair can reflect the closing price of the day = the opening price.

After analyzing the K-line, you can find the buying and selling points well (although it is impossible to predict the stock market at all, the K-line will have certain guiding value).
