There are generally two functions:

1. Become the pressure or support level of this stock, that is, the line above the price is generally called the pressure line of this stock, because of the cost Concentrated

The line below the stock price is generally called a support line, also because of the concentration of costs

2. When all the lines turn downward, it is generally called a strong decline. Channel, on the other hand, when it turns upward, it is called a strong ascending channel

It also has other functions, such as the adhesion of moving averages and the shape of moving averages, which also represent different meanings. There are many theories, so I suggest you read books and study them.
