KDJ is only used as an indicator to judge buying and selling. It is better to combine with MA line, but it is not necessarily accurate.

You can choose your favorite stock from the combination of daily line and MA line first, and then look at the weekly K-line chart. Stocks with good weekly lines are relatively stable.

When to buy, you can look at the line of 15 minutes and 60 minutes.

For KDJ, it is better to buy in lower areas than in higher areas.

But there are too many factors that affect the stock, which is not so simple to judge. Another possibility is that KDJ is already in a high-risk area and dealers will continue to do so.

By the way, battery stocks and foot-and-mouth disease concept stocks should be more popular recently.

002 139 and zhongmu are recommended.
