Is there any stock trading software that can automatically warn?

Basically all stock software has this function. .....

First of all, I don't know what type of your software is, address book, great wisdom, great wisdom L2, straight flush?

Simply say two:

For Daxin: select function, early warning function, add stock, enter early warning price, confirm and select "Yes".

Great Wisdom L2: Select tools, early warning, add conditions, price early warning (of course, you can also choose other conditions), add stocks, confirm and start early warning.
