About: - The Expert Advisor (EA) is an automated program that is written by traders or programmers. The purpose of creating an EA is to help traders in the Forex market on their trading decisions. They can be divided into two main categories. There are EAs that are programmed to provide trading signals to the traders that aim to help them with their trading decisions or there are EAs that they can place automatic trades under conditions that were set from the designer of the specific EA. - By placing automatic orders, EAs remove the psychological factor. This aims to decrease the stress for the trading from the traders and at the same time it improves the performance of an account for beginners that do not have the necessary experience in terms of fundamental and technical analysis so they can take the correct trading decisions. - However, because they are manually created by traders or programmers EAs may not be able to measure the fundamental effects of the market. As a result, the EAs may not perform very well when it comes to unforeseen events and usually traders tend to monitor their EAs in a continuous basis.
