What is a Forex Trading Robot or Forex Expert Advisor? / Axi (2024)

In the world of forex trading, a forex robot or 'expert advisor' is a program that traders install onto their trading platform in order to execute trades automatically.

These robots use computer algorithms based on pre-set signal criteria that help determine the best price at which you should buy or sell a currency pair.

In this article, we will discuss exactly what a forex trading robot is, what to consider when looking for one, and the advantages and disadvantages of using a robot to help you trade forex.

What is a forex trading robot?

A forex trading robot - also known as an expert advisor - is a trading program designed to help traders by generating signals about when to buy or sell a specific currency pair. These programs are fully automated.

MetaTrader remains the most popular tradingsoftware fortradersand mostEAswere built using the MQL scripting language. Over time, a vast number ofEAshave been built for MT4.

One of the benefits of using a forex robot is removing the trading psychology from the equation which is sometimes detrimental to a trader's performance. While the thought of an automated computer program telling you when to enter or exit trades sounds like it could be beneficial to your profits, it is not a foolproof strategy, and caution is always advised.

Who uses expert advisors?

EAsare widely used in theforextradingcommunity. SometradersexclusivelyuseEAsand choose not to engage in discretionarytrading. Others might choose to diversify anduseEAsalong with their manualtradingstrategies. Whether using EAs in general is the right fit for you or not depends on your personality as a trader. If you struggle to make decisions and feel overwhelmed by your emotions when trading, it might be worth trying out expert advisors.

On the other hand, if it is important for you to be fully in control, you may find yourself second-guessing theEAsfrequently and not feeling comfortable with using them for a longer period of time.

Ademo accountcan be of great help here, as it allows you to test theEAsin a risk-free environment. Beginners often focus on finding thebestforexrobots, but there are notradingsystemsthat are perfect, and even profitableforexbotscan stop working abruptly ifmarketconditionschange.

What do you need to consider when looking for a forex trading robot?

There is no 'holy grail' system when forex trading, regardless of whether we are talking about manual or automated trading. When considering automated trading, the first question you should ask yourself as a trader is whether you want to develop your own forex trading robot or purchase one of the many that are available on the market.

If you decide to purchase an automated trading system, you shouldn't let yourself be easily impressed by those profitable trades and the high success rate.

You can carry out a background check - by reading the reviews from other users and checking if there are any posts in trading forums or on social media. While you shouldn't rely purely on this, it will be helpful to learn about the experience other traders had with a particular expert advisor before purchasing.

Furthermore, you should conduct your own test. Many EA providers offer trial versions and you could utilise the strategy tester tool within MT4. When analysing the stats, it is important to look beyond the obvious and also consider the profit factor, maximum drawdown, and risk-reward ratio.

How are EAs built?

MQL4 and MQL5 are programming languages used to develop trading robots, custom indicators, and scripts for the MT4 and MT5 platforms. It is supported by MetaQuotes, and there is a large community of developers sharing EAs on their forums.

The first step to creating your own EA from scratch is to learn the MQL programming language. While it might seem overwhelming at first, the good news is that there are plenty of free resources available online that will enable you to learn coding EAs within a reasonable timeframe.

After you developed your own system, you should spend time backtesting it and running it in a demo environment before going live with it. Most likely, you will discover that it will need some adjustment before being applied in a live environment.

The benefit of developing your ownEAis that you can understand the logic behind it much better and you can make the necessary adjustments when needed.

Advantages of using forex robots to trade

Discover the advantages of using forex robots in your trading plan:

• Time:Being a full-time trader requires a lot of time and patience. EAs allow you to carry out trades without manual intervention. This can free up your schedule and you can dedicate more time to learning and maintaining a trading journal.
• Emotions:EAs clearly follow the instructions, and for traders who struggle with managing their emotions, it might be easier to trade that way. It will still require some discipline though, as you will eventually face a losing streak and need to stay calm.
• Diversification:Some traders who trade manually might decide to use expert advisors to diversify their strategy. For example, a long-term trader exclusively trading indices may look into short-term EA strategies that trade currencies.

Disadvantages of using forex robots to trade

We've covered the advantages above, now review some of the disadvantages of using a forex robot to trade:

• Glitches: Even if you have a broker with a reliable platform, problems with the EA could occur and potentially lead to wrong trades. If you have not developed the EA yourself or don't have the skills to fix it, it is important to have the support you can reach out to about this. Remember, brokers rarely offer EAs themselves - it will be an independent, third-party developer who puts them on the market.
• Strict rules:EAs follow rules, and cannot recognise a change in market sentiment or how a news release could affect the market.
• Due diligence:There are plenty of EAs available on the market. Some work well, some work less well. As a trader, you should not blindly trust an EA, and even if the strategy is profitable in the beginning, there is no guarantee it will run profitably for a prolonged period of time.
