Implementing System

Hi all,
I don’t know if this is the right place to ask but here goes…I’m trying to learn Elangs system.I was using FXCM but it does not have 4 hr charts so I downloaded Meta Trader 4 which he uses.I cannot for the life of me figure out how to draw EMA linesbased on the close or open,it does not give me that choice:confused: AN explanation would be greatly appreciated because the quicker I learn the sooner the day comes when I will be free and not be a wage slave anymore:)
