Imagine that, instead of trading alone, you had someone to help you. Imagine that this someone is in a perpetual search for trading opportunities, executes orders and establishes positions immediately, excels at analysis, is entirely free of emotion, never gets tired, and sends all profits your way. This is not a creature from some fantastic world. This animal is very real and is called an expert advisor. Essentially, an expert advisor is a software program that operates based on a set of defined parameters and allows a trader to trade automatically without manual intervention.
