Let's talk about K-line chart first: K-line chart is a kind of technical analysis, which was first created by the Japanese in19th century. It was used by Japanese rice market merchants at that time to record the market and price fluctuation of rice market, including opening price, closing price, highest price and lowest price, with positive candle representing the day's rise and negative candle representing the day's decline. This chart analysis method was particularly popular in China and even Southeast Asia at that time. Because the chart drawn in this way looks like candles, and these candles are black and white, it is also called yin-yang line chart. Through the K-line chart, people can completely record the market performance every day or at a certain time. After a period of trading, the stock price forms a special region or form on the chart, and different forms show different meanings. Some regular things can be found from these morphological changes. The forms of K-line chart can be divided into reverse form, arrangement form, gap and trend line. The post-K-line chart is introduced into the stock market and futures market because of its ingenious and unique drawing method.

The drawing method of K-line chart in stock market and futures market includes four data: opening price, highest price, lowest price and closing price. All K-lines are centered around these four data, reflecting the general situation and price information. If you put the daily K-line chart on a piece of paper, you can get the daily K-line chart, and you can also draw the weekly K-line chart and the monthly K-line chart. If investors need to make short-term investments, they can use short-term charts for price analysis, such as 5-minute charts, 30-minute charts and 60-minute charts.

Then, from the origin of K-line chart, do you know what K-line chart is? If the explanation in the last paragraph is written in one sentence, and all other shivering explanations are removed, the K-line chart is used to record the market and price.

There is no difference between the K-line and the pen to directly record today's opening price, highest price, lowest price and closing price, but the K-line chart draws it and produces many theories and various indicators.

If you really understand the origin and reason of K-line, do you still expect to see the secret of stock price rise and fall in one more recorded data? Can you see anything from it? I think you have understood. What I want to say is that the K-line chart is only a form of price record, and it does not contain the secret that the stock price will rise or fall in the future.

Of course, the K-line chart or price record is not useless, and it is meaningful and valuable for long-term analysis and cycle analysis.

We can judge the periodicity of an enterprise by analyzing the data of 5- 10 years, whether it is strong, weak or counter-cyclical, and try our best to judge the trading time of this enterprise. In this regard, it is meaningful to do some price statistics. Of course, this can also be achieved by other data recording methods, but we don't need to record another one ourselves because of the convenient form of K-line, which is also what we want to explain.
