I need Alerts for Vannesa Advanced System

I’m a bit new to forex, but i’ve demo traded for about 3months now.I use MT4 platform. I’ll like to set up alerts for my system (Vannessa Advanced Trading system) and i need help as to how to go about it. The guide i saw in this forum applies only to two EMA’s crossing each other or two SMA’s crossing each other, but i have One EMA crossing against two SMA’s in my system. how do i set alerts for it? thanks in anticipation of your advice.
