Installation

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
