How Important Is Risk Management?

How to explain leverage in the forex market?

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

If you have a bad mentality, does this mean that you are not suitable for trading?

I have had a few positions liquidated recently, but fortunately the losses were not very large. I would like to ask everyone, is there any way to prevent liquidation? Is there any trading discipline?

How do you handle when you're in the "wrong trade"?

I heard from trading masters that transactions are divided into correct transactions and incorrect transactions. Profit orders may be wrong transactions, and loss orders may also be correct transactions. How do you define "wrong trade"? What is the most impressive mistake you made? What kind of result? What enlightenment did it have on your subsequent orders? I hope you guys can share it, thank you!
