What is the only certainty in countless changes?Those who delete posts and pictures are liars, and they can't be faked only when they are posted on the same day, because anyone with eyes can see it if it goes up or not.If you feel unconvinced, you can buy stocks on the same day as me and send them out on the same day, so that everyone can see for themselves whether they have risen or not, instead of deceiving everyone with your poor P-chart, or satisfying your pathetic vanity of losing money every day to find a sense of existence.

Those who delete posts and pictures are liars, and they can't be faked only when they are posted on the same day, because anyone with eyes can see it if it goes up or not.So I take buying down as the core basis of trading. There is a limit to the decline of individual stocks in the short term, and when it reaches the limit, it will rise immediately. Therefore, grasping the limit decline of individual stocks and turning it into your own opportunity to enter the market can help you buy before the rise.

Those who delete posts and pictures are liars, and they can't be faked only when they are posted on the same day, because anyone with eyes can see it if it goes up or not.What is iron logic?
