What should you learn most when you start trading? It is not MACD, golden cross, dead cross, or various indicators; it is not waves, Dow theory, or even more so, the probability theory in mathematics.
Probability theory, which can be learned in elementary school, is also the simplest and most commonly used knowledge! In fact, the one I am most grateful to is my elementary school teacher. Although he only taught me for a few years, the knowledge he gave me is richer than the knowledge I learned in middle school. It makes me very useful in trading and I can apply what I have learned. So this is also the reason why I insisted on trading in the first few years!
