666 points profit in DowJones

What is your basis for entering the market?

What do you think is the most important thing in trading?

As a "trader", what trading discipline do you have to restrain yourself?

What is the core secret of your profitable trading? Can you share it?

The core of what I want to ask is the meaning of "tools and strategies". It's like drawing a hand of cards. How to play this hand to win is the core. In trading, what you need to know is how to design your own "cash machine", that is to say, what core profit do you rely on? Turn the transaction into a complete planned planting and harvesting. What do you earn money from? What is the core secret?

Do you guys have any good suggestions to save novice Huiyou like me from taking some detours?
