How to use:

1. Add the following include line to your indicator or expert advisor

   #include <ScriptCaller.class.mqh>
   
   

2. Add the following code to initialize/deinitialize class instance.

   ScriptCaller* g_scriptCaller = NULL;
   
   int OnInit()
   {
      g_scriptCaller = new ScriptCaller();
      return INIT_SUCCEEDED;
   }
   
   void OnDeinit(const int reason)
   {
      if (g_scriptCaller) {
          delete g_scriptCaller;
      }
   }
   
   

3. Finally, put the following code to call script!

   g_scriptCaller.callScript("ScriptName"); // Do not end with .mq4
   
   

4. If the script shows input dialog, and you want to close it automatically, call as follows.
   

   g_scriptCaller.callScript("ScriptName", true); // if the 2nd parameter is true, dialog will be closed automatically.
