I still remember a student asking me a long time ago (really a student, I teach mathematics, and occasionally talk about stock concepts. Later, after graduation, he kept in touch with me and started investing), how should the teacher make a correction? He was using the moving average Ma to look at it. My answer is that it doesn’t matter how the market goes, but these systems at least have a higher winning rate or profit-loss ratio than those who do it randomly. The correction may fluctuate and wait for the line to go up. There may be a correction, or the price may fall when it is a correction. It may not necessarily fall if there is any deviation from the moving average, nor may it not stop falling after it falls, because the moving average system is all artificial support and resistance. We can only say that this way the winning rate is It will be on the high side, so I can’t say it will definitely win.
