- **What:** Cached static symbol properties (e.g., point size, digits, lot size constraints) in global variables during `OnInit`.
- **Why:** The `SymbolInfo...()` functions were being called repeatedly in performance-critical trading functions, adding unnecessary overhead.
- **Impact:** This change reduces the number of expensive function calls in the `OnTick` hot path, resulting in a measurable performance improvement.
- **Measurement:** The improvement can be verified by profiling the EA's execution time, which will show a reduction in the time spent in the refactored functions.
