Are technical indicators really useful?

Indicators have their own uses, just like scooping soup with hedges, making cakes with axes and drinking water with chopsticks.

There are many indicators in the stock market, but most systems have their own indicators, which are often the best indicators, such as MACD, kdj, W& etc. L and other indicators are excellent indicators in the sub-graph, while MA, WTOW and BOLL in the main graph are all good indicators. Many popular color indicators are made by modifying the expressions of these indicators. If the indicator has a deep understanding of the stock market, his indicators may be better than the traditional indicators, but if he is only a computer expert and doesn't know much about the stock market, his indicators are not as good as the traditional indicators.

Traditional indicators cannot be used as soon as they are available. You need to modify and optimize them according to your own needs. Compared with me, the system comes with parameters 5, 10, 20, 60. If you look at the short term, this indicator system can be used. If you look at the center line or the long line, you have to modify the parameters of this system. The center line takes 20 as the express line, and the combination is 60, 120.
