I'd stay away from Zulutrade. I've never met anyone that has made much money from it.
Check out connectforex.com it's a bit more professional.
Just my take on signals - I personally think that retail traders stand a better chance of success following signals than trying to trade on their own. Consider the rate of success for individual traders is less than 1%, using a verified signal service that can show long term verified gains isn't such a bad idea.
