Some friends always want to buy at the lowest price and sell at the highest price, but I think that's impossible. People who have this idea are not experts. Only crops know the extent to which stock prices may rise or fall, and crops cannot completely control the trend, let alone you and me. I used to hope to reach this level, but now I have changed my mindset. I don't even look at stocks that hit new lows, and there may be new lows below them. I only buy stocks that have a rise of about 10% from the bottom, and I have to enter the upward channel, but this often leads to the most fleshy part.
