There is a popular saying in the stock market: "It's not how much you make in the stock market, but how long you live", and it is this saying that makes me have palpitations about long term investment.
The broader market out of the downward channel, the shares generally stop falling, the broader k-line pattern has come out of a good pattern, you can consider entering the market.
Only when K-line analysis is combined with volume analysis can we truly read the language of the market and gain insight into the subtleties of stock price changes.
