What is Position Sizing?
Position sizing is the most critical component of risk management. It answers the question "How much should I buy?" rather than "What should I buy?". By adjusting your position size based on the distance to your stop loss, you ensure that regardless of the trade's outcome, you never lose more than a fixed percentage of your account.

- Consistent Growth: Normalize risk across different trades, making your equity curve smoother.
- Remove Emotion: Make decisions based on math and logic, not greed or fear.
