we took the usdjpy trade

How can one be called a qualified trader?

A handful of bitter tears, I have been trading for five years, and I still lose money, what should I do?

What cognitive biases do we have to overcome?

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

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