Traders need to carefully implement their trading plan, but also need to discern whether the various negative benefits of the market are important and need to be paid attention to, and after identification, they should quickly decide whether to change the details of the investment plan, instead of only saying afterwards (each time it can only be a major premise, it is okay to review and find the reason) afterwards to say what is the reason for the rise and what is the reason for the fall, but never decisively decide what to do when the news comes out.
