Divergence Ea modification

Hi guys...i just got this multi oscilliator divergence ea...has a bunch of oscilliators for trading divergences, it however still lacks a crucial one that i use..."macd oscilliator".....is there a way to input this oscilliator into the source file(which i would gladly share here). would be glad for help on that aspect(or perhaps a reference to a previous multi divergence ea with the macd histogram oscilliator)....once again thanks
