+     }
+
+//--- 5. Write Data to CSV File ---
+// Write the header row first
+   FileWrite(file_handle, "time", "open", "high", "low", "close", "tick_volume", "real_volume", "spread");
+
+// Loop through the copied rates and write each candle to a new line
+   for(int i = 0; i < copied_count; i++)

+      // Convert Unix timestamp to a human-readable string for better readability in the CSV
+      string time_str = TimeToString(rates[i].time, TIME_DATE | TIME_MINUTES | TIME_SECONDS);

+      // Write one line to the CSV file
+      FileWrite(file_handle,
+                time_str,
+                rates[i].open,
+                rates[i].high,

+   FileClose(file_handle);
+   PrintFormat("Successfully exported %d candles to '%s'.", copied_count, file_name);
+   Print("You can find the file in the terminal's Data Folder under MQL5/Files/.");
