 ## 3. MQL5 Implementation Details
 
-* **Universal Engine (`Symbol_Strength_Calculator.mqh`):** The core logic is encapsulated in a flexible engine that can handle any symbol string provided by the user. It includes robust error handling for missing data or synchronization delays.
-* **Dynamic Dashboard:** A custom-drawn dashboard panel in the indicator window provides a real-time, sorted list of the active symbols with their exact strength values (to 3 decimal places), color-coded to match the chart lines.
-* **Optimized Performance:** The indicator employs smart history limiting on the first load to prevent lag, and subsequent updates are incremental.
+* **Universal Engine (`Symbol_Strength_Calculator.mqh`):** The core logic is encapsulated in a flexible engine that can handle any symbol string provided by the user. It includes robust error handling for missing data or synchronization delays, ensuring the indicator doesn't freeze the terminal while waiting for data.
+* **Robust Data Handling:** The indicator includes advanced synchronization checks (`IsDataReady`). It ensures that historical data for all selected symbols is fully loaded and synchronized before performing calculations. This prevents the display of misleading or "glitchy" lines during chart startup or timeframe changes.
+* **Safe Smoothing Algorithm:** The smoothing logic is designed to handle data gaps and initialization phases gracefully, preventing mathematical overflows or "exploding" values that can occur when smoothing incomplete data series.
+* **Dynamic Dashboard:** A custom-drawn dashboard panel in the indicator window provides a real-time, sorted list of the active symbols with their exact strength values (to 3 decimal places), color-coded to match the chart lines. It automatically hides symbols that are disabled in the settings.

 1. **Check Symbol Name:** Ensure the symbol name entered in the parameters matches **exactly** what is listed in your Market Watch window (e.g., your broker might use "XAUUSD" instead of "Gold", or "SPX500" instead of "US500").
 2. **Check Experts Tab:** Look at the "Experts" tab in the Terminal toolbox. The indicator will print an error message if it cannot find a symbol (e.g., `Symbol 'Gold' not found!`).
