Mql4 Error Code 5004
up vote 0 down vote favorite I wrote an EA using an indicator which reads in a configuration file. This configuration file is put in the folder MQL4\Files. When I run the EA with the live chart, it works well. But when I tried to test this EA using the strategy tester, it returns an 4103 error: can not open file. Any idea why this happens? And how to address mql4 error 130 this problem? file algorithmic-trading metatrader4 mt4 share|improve this question edited Dec 26 '15 at 19:16 user3666197 7,85721330 asked Dec 23 '15 at 15:53 Carter 213415 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted A thing that happens is a feature of the MQL4 ecosystem: For security reasons, work with files is strictly controlled in the MQL4 language. Files with which file operations are conducted using MQL4 means, cannot be outside the file sandbox. The file is opened in the folder of the client terminal in the subfolder MQL4\files ( or Tester\Files in case of testing ). If FILE_COMMON is specified among flags, the file is opened in a shared folder for all MetaTrader 4 client terminals. How to address this? Simply, take care of using just the "relative" specification of the file-path ( and keep in mind, which of the three possible root-directory cases is being used in which modus-operandi ). aFH = FileOpen( "aFileInsideDefaultDirectoryRoot.txt", ... ); // // USED: // in Strategy Tester---+ // plain EA-mode-----|------------+ // FILE_COMMON-mode--|------------|----------------+ // | | | // RESULTS: v v v // in a file in { tester\files | MQL4\Files |
