Trading is a game of Probability and Technical analysis is just a guide for a trader when he wants to make a buy or sell decision
when trading in the short term but technical analysis is not effective for predicting future prices.
A professional trader will build a solid trading system combined with the right money management and the right trading psychology
That's right, some market analysis methods can be used for short-term trading. but for the long term, I believe we just need to choose the right assets for us to prepare in the future. because we will never know the future state of the market. while the project, we can choose and analyze which is good and which is not good.
