K-line refers to the K-line chart in the stock trend, which originated from the Tokugawa shogunate era in Japan (1603 ~ 1867) and was used by rice market businessmen at that time to record the rice market and price fluctuations.
Later, because of its ingenious and unique drawing method, it was first introduced into futures. Many people think that the K-line started from the stock market.
Through the K-line chart, we can completely record the daily or periodic market conditions. After a period of trading, the stock price forms a special region or form on the chart, and different forms show different meanings.
