The easiest way to trade

Dear Hui friends, how to solve the situation of small profits and big losses?

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?

What do you think are the core competitiveness of a good broker?

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?

Why do successful traders not advise others to trade?
