Since MetaTrader 4 build 880 was released, it's no longer easy to programmatically fill values in Login dialog.

This library hides the complicated stuff and provides easy to use API to login to any MetaTrader 4 account from within MQL4 script/expert.

Any contribution appreciated.

// Just in case...
   if(loginDialogIsOpen()) closeLoginDialog();

// Let's do it!
   if(auth("ACCOUNT_NUMBER","PASSWORD","SERVER IP/HOSTNAME"))
     {
      Print("Hooray, I found the login dialog, inserted credentials, now wait until MT4 connects :)");
     }
   else
     {
      Print("Sorry, I could not even find the Login dialog... Is your MT4 older than v880 or something?");
     }
