+While MetaTrader 5 (MQL5) does not natively support a formal unit testing framework, the goal of writing automated tests to:
+- Verify correctness
+- Support ongoing development
+- Ensure long-term maintainability
+
+This directory is intended to hold future test scripts that validate core components (e.g. position sizing, stop loss logic, and indicator handling) using **script-based test runners** and **mockable components**.
