What is the most important trading rule?
The most important rule is to protect capital. Use a written plan, define risk before entering, keep position sizes sensible, and avoid trading money you cannot afford to lose.

Spot on. Protecting capital is the absolute foundation of trading, especially when you step into the prop firm arena. Maintaining sensible position sizes and strict risk control is what keeps you clear of daily loss limits and hard drawdown breaches.
When you are managing evaluation or funded accounts, treating risk management as a non-negotiable routine is the only way to ensure longevity. A written trading plan removes emotion from the equation, keeping your sizing disciplined even during volatile market sessions.
