After reading the material I could find and trying various solutions, I still cannot get the ChartApplyTemplate to work. The template is not applying to the chart being opened and the error I receive is 5002 - the file cannot be found. Here is my code: int iChartID = ChartOpen(sChartNameL,5); ChartApplyTemplate(iChartID,"C:\\Users\\Jean\\AppData\\Roaming\\MetaQuotes\\Terminal\\DA3C92B1779898CC0CACD726A655BECB\\Files\\ADX.tpl"); Print(GetLastError()); I have also tried: int iChartID = ChartOpen(sChartNameL,5); string sTerminalDataPath = TerminalInfoString(TERMINAL_DATA_PATH); ChartApplyTemplate(iChartID, sTerminalDataPath + "\\MQL4\\Files\\ADX.tpl"); I have tried to place the template in various directories. Files as stated above but I have also tried to insert a files subdirectory in the mql4\experts subdirectory and also tried to use the files subdirectory under the MQL4 subdirectory. I have also left the template in the default templates directory. I have tried these various locations as I believe Metatrader has a sandbox environment for where files may be accessed. Please can you help me.

You are using the wrong variable type for your chart ID, it should be of type long . The code should read as an example. long iChartID = ChartOpen("EURUSD",5); ChartApplyTemplate(iChartID,"Popular.tpl"); For the location of the template file, from the documentation: if the backslash "" separator (written as "\") is placed at the beginning of the path, the template is searched for relative to the path _terminal_data_directory\MQL4, if there is no backslash, the template is searched for relative to the executable EX4 file, in which ChartApplyTemplate() is called; if a template is not found in the first two variants, the search is performed in the folder terminal_directory\Profiles\Templates.
