The daily K-line chart, also known as the candlestick, was originally a tool used by Japanese rice merchants to express the rise and fall of rice prices. It was later introduced to the stock market and gradually became popular in Southeast Asia. K-line charts are very popular among investors for their intuitive and three-dimensional characteristics. Practice has proven that careful study of the K-line chart can more accurately predict the market outlook, and can also more clearly judge the balance of power between the long and short sides, thereby providing an important reference for investment decisions.
