Where should beginners start trading?

My usual trading system continues to fail, what should I do?

If a trading system built by myself often fails and causes losses, should I abandon this system and replace it with another one? Is there a stable and profitable trading system?

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

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?

Winning ratio and profit-loss ratio, which one do you value more?
