A Forex signal is a suggestion for entering a trade on a currency pair, usually at a specific price and time. The signal is generated either by a human analyst or an automated Forex robot supplied to a subscriber of the forex signal service. Due to the timely nature of signals, they are usually communicated via email, website, SMS, RSS, tweet or other relatively immediate method. I have personally had great experience with Forex Vice. In fact I have been following them for 8 months. Its basically a service that you install their EA and when they make a trade, you copy their trade. However it is kind of expensive and may not be good start for beginning traders.
