1. You need to understand the concept of cost. All activities are based on cost. It is impossible for any organization or individual to make an investment regardless of cost, so pay attention to the cost moving average and learn how to look at it.

2. You need to understand what band theory is (you don't need to think too complicated). If you connect the N-word in the K-line diagram like this, you will find that it is similar to the N-word, which can't go up all the time in a cycle. The main force can't invest a lot of money, and it is impossible to watch others make money while he doesn't, so when it goes up to a certain extent, it will be called back to suppress (profit-taking). What you need to pay attention to is that after the N-word's low and high

3. You need to understand the trend. Everything you do is in the hope of making money, so you should not operate against the trend. In the upward trend, don't be short, and don't be long in the downward trend. The N-word theory is also based on the trend.

You will find all the information about the above three points, study them carefully and memorize them, then look at them one by one, draw lines while watching them, and gradually accumulate your experience.

You can buy books such as Walking the World with a Ruler, Handicap, Five Lines Blooming, and Quantitative Analysis of Numbers, and search online for terms you don't understand.

If you can't do stocks, it is not recommended that you do any other investment products, such as foreign exchange, futures, gold, comprehensive commodities, spot and so on.
