The easiest way to trade

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?

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 can you see the general direction right, but make a bad point in the transaction, and lose money instead?

What kind of system can accurately locate support resistance and trend when doing transactions?

Why is it so hard for an analyst to be the best trader?
