Most Forex signal services require your computer to be within your hands reach along the trading time, so you don't miss a signal due to a delay.
But now, this does not matter anymore if we consider what's called a "Trade Copier". This is an automated MetaTrader robot (Expert Advisor) that is commanded directly by the signals service trader.
An authentic Forex signal service providing such a trade copier is "Vladimir's Forex Signals & Mentoring": they use multiple sources to prepare and refine their signals, including Vladimir's own trades, bonus trades, as well as guest pro traders and a real money account traded by worldly-wise followers. So that, if you have no time to trade, or reading charts for a long time is so boring for you, you can get the trade copier automatically grab and perform the signals for you. You can even leave it trading while you're in your bed.
