Risk-to-reward (R:R) ratio is a critical concept that determines whether your trades are worth taking. A good R:R ratio ensures that your potential reward outweighs your potential loss, typically aiming for at least 2:1 or higher. For example, if you risk $100, your target should be at least $200. This ensures that even with a lower win rate, you can remain profitable over time. Calculate your R:R ratio before entering any trade and adjust your targets accordingly. Avoid trades with poor ratios, as they often lead to inconsistent results. By focusing on favorable R:R setups, you build a sustainable path to long-term success.
