EURUSD LONG TRADE

Can retail investors make a lot of money by trading? How can I earn it?

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?

What should I do if my trading system encounters a retracement?

Why do really successful traders never share their methods or strategies?

Seeking expert guidance, what is the difference between left-hand trading and right-hand trading?
