Trading indicators are available in many search engines. You can search by yourself, such as communication indicators and great wisdom. But I recommend you to use the stock express investment platform. You can download the "stock through train" for free, which is easy to use and suitable for investors. The specific method is Baidu's "Stock Express Train" and then click the first "Free Stock Express Train, Rapid Wealth Growth" to download the completely free version of "Treasure Island Stock Express Train". Including free stock closing, understanding the latest stock investment strategy and operation skills. Very useful. I hope it helps you.
