Explain the difference between the highest price and the closing price > the difference between the lowest price and the opening price. The red column represents that the closing price is greater than the opening price, that is, it rises that day. The bottom of the column represents the beginning and the top represents the end. The upper shadow is the difference between the highest price and the closing price, and the lower shadow is the difference between the closing price and the lowest price. When the upper shadow line is longer than the lower shadow line, the difference between the highest price and the closing price is greater than the difference between the lowest price and the opening price, which probably means that the stock will fall. Looking at the K-line of stocks is a very common means of stock trading. The stock market is changing rapidly, so we can use the K-line to find out some "rules", so as to make a clear analysis, make better investments and gain profits. The stock K-line is the K-line chart. We also call them candle charts, daily charts, yin and yang lines, etc. K line is its most common name. It was first used to calculate the daily rise and fall of rice price, and then it was applied to stock, futures, options and other securities markets. K-line is a columnar line with hatching and entity. 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. The positive line is not only represented by red, but also by white columns and hollow black boxes. Choose green, black or blue solid columns to represent negative lines. Besides these, when the "crosshair" is seen by us, the solid part is transformed into a line. In fact, the meaning of the crosshair is very simple, that is, the closing price of the day is the opening price. Through the analysis of K-line, we can grasp the trading point well (K-line is also instructive, although the stock market is unpredictable), and it is also the best manipulation for novices. I want to warn you here that K-line analysis is very difficult. If you just started trading stocks and don't know K-line, I suggest using some auxiliary tools to help you judge whether a stock is worth buying.
