  CSVFile.SetValue(r, "off" , double to string ( symbol information double ( symbol (), SYMBOL_ASK ), _number ));

// Demonstrate SetValue by column index (index 0..n-1). Here we set the first column of the first row to a custom value if (CSVFile.RowCount() > 0 && CSVFile.ColumnCount() > 0 )
    CSVFile.SetValue( 0 , 0 , "CUSTOM_TIME" );

//Write CSV to file. If necessary, ANSI encoded files can be written via FILE_ANSI. if (CSVFile.WriteCSV(filename, true , ";" , file_ANSI )) {
Print format ( "Successfully written %d rows and %d columns: %s" , 
                CSVFile.RowCount(), CSVFile.ColumnCount(), file name);
  } other {
printFormat ( "Error writing CSV file: %s" , filename);
  }
