If you buy a target, you need to know:

1. Is there a banker

2. How is the description

3. What is the profit and loss ratio

4. When is the right time to open a position

5. There is a position

6. What proportion of your overall position should be placed on this target

7. What is the target price and how to sell it

8. If the judgment is wrong, how to stop loss

The above are 8 questions that I will think about every time I buy a target. I hope you will develop this habit.
