What method do I usually use to judge the support level and resistance level? I think this is the most accurate method? It is to observe the historical price of the K-line chart of trading varieties. What is the highest point? What is the lowest point? What is the closing price? These can often explain the problem. This method of judging the support level and resistance level can be realized on the K-line chart (Balox) at any time: daily chart, weekly chart and monthly chart. In most cases, the price will be concentrated in a certain area, not a certain point; If so, I will think that the area is a support area or a resistance area. It should be pointed out that the range should not be too large, otherwise it will be of no reference significance to investors. The top or bottom of the stock market often constitutes resistance or support; The unfilled gaps in the technical drawings also form effective support or resistance levels; The EMA also helps investors to judge the support level and resistance level; Observing the trend line can also judge the future support and resistance of the market. It should be noted that when the main support level is broken down, the support level is transformed into the main resistance level; When the main resistance level is broken, it becomes the main support level. Another way to find support and resistance levels is to observe the price retreat during operation? That is, the price fluctuation contrary to the current trend is also called adjustment or correction. Let's take a round of rising market as an example: the market rose from 3000 points to 4000 points, then the price turned back to the next point, reaching 3500 points, and then continued to attack and push the price higher. 3500 points is the 50% retracement of the market from 3000 points to 4000 points. 3500 points proves that the support is very strong. In other words, because the price drops by 50% and then turns around again, the 50% retracement proves that the support is effective. The same is true of the rising callback in the falling market. Some retracement percentages are of great practical significance for judging the support level and resistance level, such as 33%, 50% and 67%. There are also two numbers called Fibonacci odd numbers (Fibonacci is a mathematician): 38% and 62%. These five groups of figures are very helpful to judge the support level and resistance level. Most good trading system software has these percentage retracement tools. As long as you click the starting point on the K-line chart in the price trend with the mouse, and then click the high point of the price, the percentage retracement number will be automatically displayed on the technical chart. Another way to judge the support level and resistance level is to measure these two positions by geometric method based on a certain price. Gann, who has a legendary experience in stock and commodity futures exchanges, has actively advocated this method. He also used the five figures mentioned above to calculate his geometric angle (balox). Some more advanced trading systems have GANN fans to help you measure this angle. Finally, the psychological price is used to determine the support level and resistance level, which are often integers. In the market, this method has been tried and tested. A method for calculating adhesion resistance potential: golden section method: the first resistance potential = lowest price *1.191; Second resistance level = lowest price *1.382; Third resistance level = lowest price *1.618; The fourth resistance level = lowest price *1.809; Fifth resistance level = lowest price *2.
