Protect the capital
First rule of trading:
Do not lose your capital.
Before thinking about profit, think about protection.
Always:
Stop loss
Risk management
Reasonable position
A trader who protects their capital survives for a long time.
Emotions
Fear and greed destroy more accounts than the market.
A disciplined trader:
Do not panic during drops
Do not become euphoric during rises
Calmness is a weapon.
