ACE
There is an iron rule in trading that will not change in another 100 years
Suitable forever from generation to generation
A high price is good and a bad thing, a low price is bad and a good thing
It is negative to increase holdings at high levels, and it is good to reduce holdings at low levels.
High position is good, run quickly when the price rises
It is bad to sell at a low position, and rush inward when the volume shrinks.
How do experts speculate in the market? Reverse thinking is indispensable
Emotions are running high, get out quickly
Reduce the volume to the extreme and then do it harder
