Don't sign up for a signal service expecting to make money right away. If it was that easy, 90% of traders would just join signal services and forget about it.
However, unlike many people who are completely against it, joining a live chat room or website that is a paid service can help you learn IF the members/administrators are experienced and successful traders and have the ability to teach others. Before paying money for a service like this though, you must study on your own and know all the basics.
What instruments do you want to trade? Futures, forex, stocks?
