1Why Diversification Is Illusory Without Correlation Checks
Trading EUR/USD and GBP/USD simultaneously can feel like diversification, but these pairs often move in the same direction because they both trade against the US Dollar. If USD strengthens, both pairs typically fall – meaning you have effectively doubled your USD risk.

Correlation coefficients range from -1 (perfectly inverse) to +1 (perfectly direct). Any coefficient above 0.7 or below -0.7 should trigger a conscious decision about whether your combined exposure is intentional.
Key Takeaways
- Understanding market psychology is crucial for consistent profits
- Risk management should always come before profit targets
- AI tools can enhance but not replace human decision-making

Consider the total risk of all correlated trades as a single position and manage it with a combined maximum exposure rule.
