click on the "Spread Controller" and then if you click on the "contact us" in the yellow bar and simply ask for info on the spread controller they will send you the link to download it. It is free no strings attached, (they have never sent me anything other than the link)

I do not know if it will work with your simulator but it does let you set the spread to your choosing and will run in the mt4 tester with that spread until you remove the script. So it could very well work with your simulator..
