It seems that like Alpari UK, Alpari RU has also stopped to offer their data.
You will probably need to do this once you have generated the fxt files :

The problem with dukascopy data is that you can not do a backtesting on more than 12 months as MT4 can't work with a fxt file size more than 2GB. You will need to optimize on 2010, then to test on 2009, 2008 and 2007.
You should start with one pair to understand the method also as you could get some issues like to have only partial data.
In download_dukascopy_data.php, replace :
$currencies = ... ;
$currencies = array("EURUSD" => 1175270475);
