Sister Fa Dianjin: Are you a novice, a veteran, or a master?

My usual trading system continues to fail, what should I do?

If a trading system built by myself often fails and causes losses, should I abandon this system and replace it with another one? Is there a stable and profitable trading system?

What cognitive biases do we have to overcome?

Fund management has always been a headache for me. May I ask you guys, how can I do a good job of position control?

Are you happy doing business?

There is no such question, so I mention it.

I resigned yesterday, due at the end of the month, I want to do trading full-time, but I don’t know how far this road can go?
