How to set stock warning for Apple mobile phone?

Take the flush software as an example,

1. Enter the flush software and click the "Smart" option in the menu bar.

2. Select "Stock Reminder" in the "Smart" option.

3. Click "Add Reminder".

We set the stock price to rise to 4000 points, give a warning when it falls to 3000 points, and then click OK.

5. After setting, do whatever you want. When you touch the price of 4000 or 3000, it will automatically remind you, and then it will be sold again.
