The real deal with trading on MT4 is understanding what EA is before deciding whether to use it or not. I see many people confused about the term Expert Advisor, but in fact, it is a programmed system that helps us trade automatically.

Originally, new investors had to sit in front of the screen all the time, watching charts, analyzing data, making buy or sell decisions repeatedly. Especially in the FOREX market, which is open for trading up to 20 hours a day, fatigue is inevitable. Sometimes, decisions are wrong because we are tired, scared, or greedy, and money disappears.

This is where EA comes in to help. It is a set of computer commands programmed to analyze statistical data, make buy or sell decisions, and manage Stop Loss and Profit Target automatically—all without human supervision.

The advantages of EA are many. First, you don’t have to sit in front of the screen; EA can operate 24 hours a day according to the set pattern. It doesn’t get tired or scared, and it makes decisions based solely on data, without emotional interference.

Second, with enormous amounts of data and news flowing in every second, people can get confused about which information is important. EA helps with this because it will only select information relevant to its trading pattern. It won’t be fooled or distracted.

Third, EA has an accurate Stop Loss system. When a trade moves to the predetermined loss point, EA will immediately issue an order to exit, reducing losses and preventing money from disappearing due to forgetfulness or not being in front of the screen. When the market rises, EA records profits according to the set target.

However, EA is not a perfect trading method. It has limitations. The first issue is that an EA programmed for FOREX cannot be used for gold or oil; it is specific to one asset class.

The second issue is that EA only follows the preset instructions. If you set a profit target of 6%, it will close the position at 6%, even if the market rises to 20%. There’s no flexibility or adaptation to market conditions.

The third issue is that EA does not guarantee you won’t wipe out your account. If the system misreads data or if there’s abnormal market movement, EA might issue wrong orders, resulting in losing all your money.

My perspective is that you should use EA alongside manual trading. In the beginning, when you lack experience, EA can help you make some profit or prevent losses. At the same time, trade some manually to learn, understand, and develop your skills.

What EA still doesn’t do well is decision-making when opportunities increase. Usually, EA stops immediately when reaching the target, but with awareness, we can see opportunities and continue to profit. Therefore, learning to trade on your own remains important. EA is a tool to assist, not a complete solution.
