K-line Jianghu Academy: How to judge whether you can trade full-time?

What should I do if I am about to liquidate?

I have been unable to set the stop loss in the transaction, how can I do a good stop loss?

Ask for advice on how to manage trading positions in order to achieve long-term stable profits?

Why are there so few stable profitable Huiyou? There are many liquidated and repeated losses? Is it really because of technical analysis?

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