GBPUSD Trading Tip Outcome

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 should I do if my trading system encounters a retracement?

What should I do if I am about to liquidate?

As far as I know, many master traders will rely more on the sense of the market, how to cultivate this feeling?

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?
