// This EA was made to easily export indicators results |

// |
// Instructions: |
// Modify the InitializeHeaderFile() function so that it |
// displays the CSV column headers in the same order |
// you set the indicators. |
// Modify the WriteHistoryData() function so that it |
// displays the indicators you want to export (remember |
// to place them on the same order you used on the |
// InitializeHeaderFile()). |
// Compile the expert. |
// Run the expert on the desired time range using the |
// Strategy Tester. |
// Results are saved at your MetaTrader/tester/files/ |
// folder. |

Compilation successfull, but the .csv file doesn't create in metatrader/tester/files directory. Any ideas, where could be the problem?
