There are many types of moving averages, which can be roughly divided into the following categories. It depends on yourself which one you use. The one that suits you best is the best. (Written by myself, not copied and pasted)

1. A moving average. M20 is generally used, and the most famous usage is "Grandvey's moving average rule" (also known as "eight dozen moving averages"). This method of judgment is relatively subjective. Whether "subjective" is good or bad depends on your own preferences.

2. Two moving averages. MA20 and MA10 are commonly used in the short-term and can be used in two ways: golden cross, dead cross, and separation. The distance multiplication is to look at the distance between the two moving averages. EMA144 and EMA169 (also called "Vegas Channel") are commonly used in the long term and are used to look at positions. The "Vegas Channel" is considered a relatively reliable strong support and resistance line.

3. Three moving averages. Introducing a "crocodile line formation" recommended in the chaos trading method. MT4 comes with it, in the Bill Williams project. For specific usage, please refer to "Chaos Trading Method".

4. Multiple moving averages. The most famous multi-moving average system is the "Guppy moving average". There are 12 Guppy lines in a day, 6 Guppy long-term lines, namely EMA30, 35, 40, 45, 50, and 60; 6 Guppy short-term lines, EMA3, 5, 8, 10, 12, and 15 respectively. Guppy moving average is broad and profound and can be used in many ways. Guppy himself used it to judge the "stability" of the trend, but later everyone discovered that the Guppy long-term is also a good position indicator; the convergence and divergence of the Guppy moving average can reflect market sentiment; and some people use the Guppy moving average Cross pattern to determine trend reversal.

5. The above are all famous usages, and there is also a set of "non-famous moving average system": 4 moving averages. The two fast lines are EMA13 and EMA26 (which are the parameters of MACD), and the two slow lines are EMA52 and EMA102. The last two bars are exactly 4 times the previous two bars, which are equivalent to EMA13 and EMA26 in a larger period. The usage is that the golden cross of EMA52 and EMA102 determines the direction, and the golden cross of EMA13 and EMA26 determines the entry and exit positions.

——Finally, to summarize, the moving average is the moving average, and the moving average has its limitations. Of course, I believe that there are definitely masters who only use moving averages for trading, but most masters do not only use moving averages. Therefore, don’t be obsessed with the moving average. All the above methods will cause losses when encountering consolidation. The parameters of the moving average are not the most critical, but how you use them is the most critical.

——As far as I am concerned, I have experienced the learning process of two moving averages - the Alligator line and the Guppy moving average. At present, I prefer to use the Guppy moving average.
