Best Platform for Expert Advisors: MT4 vs MT5 Explained for Beginners
Last Updated: July 2026
Choosing the Right Platform Doesn’t Have to Be Difficult
One of the first questions traders ask when they start using Expert Advisors (EAs) is whether they should choose MetaTrader 4 (MT4) or MetaTrader 5 (MT5). Both platforms are widely used around the world, both support automated trading and both have large online communities—but they are designed for slightly different purposes.
The problem is that many comparison articles immediately begin talking about programming languages, execution threads, optimisation engines and other technical features. While those differences are important, they often confuse beginners who simply want to know which platform is the better choice for learning and long-term trading.
In this guide I’ll explain the differences in plain English. We’ll start with a simple recommendation, compare the platforms side by side and then look at the more advanced technical features for traders who want to understand how Expert Advisors really work.

AI Overview
For most new traders, MetaTrader 5 (MT5) is the better platform for running Expert Advisors. It offers faster backtesting, improved performance, support for more asset classes and is actively developed by MetaQuotes. MT4 remains a reliable choice if you already own older Expert Advisors written in MQL4 or your broker only supports MT4.
Choosing the right platform depends on your goals. Beginners starting from scratch will usually benefit from learning MT5, while experienced traders with an existing library of MT4 robots may prefer to continue using MT4 until they are ready to migrate.
This guide compares both platforms in plain English before examining the technical differences that matter to advanced traders and EA developers.
🏆 Quick Recommendation
If you’re new to automated trading, choose MT5.
- ✅ Better long-term platform
- ✅ Faster strategy testing
- ✅ More powerful programming language (MQL5)
- ✅ Supports more markets than Forex
- ✅ Actively developed with new features
Choose MT4 only if you already own MT4 Expert Advisors or your broker doesn’t support MT5.
MT4 vs MT5: Side-by-Side Comparison
Now that you’ve seen the short recommendation, let’s compare the two platforms feature by feature. This table highlights the differences that matter most to beginner and intermediate traders without diving into unnecessary technical jargon.
Remember that both platforms are excellent trading platforms. The goal isn’t to prove one is “good” and the other is “bad.” Instead, it’s about choosing the platform that best matches your current experience and future trading goals.

Beginner Summary
If I were starting my trading journey today, I would choose MetaTrader 5. It has become the industry’s primary development platform, offers better performance, supports a wider range of financial markets and provides more powerful tools for testing and developing Expert Advisors.
That doesn’t mean MT4 is obsolete. Thousands of traders still use it successfully every day. However, if you’re starting from scratch and planning for the future, MT5 is the platform I recommend.
Why MT5 Performs Better Than MT4
Now that you know which platform is generally the better choice, let’s look at why. Don’t worry—you don’t need to be a programmer to understand these differences. I’ll explain each feature in simple language and show how it affects everyday trading.
Many online comparisons focus on technical specifications that matter mainly to software developers. As a trader, you only need to understand how these improvements can make your trading faster, more efficient and easier to manage.
MQL4 vs MQL5 Programming Language
Every Expert Advisor is written using a programming language. MT4 uses MQL4, while MT5 uses the newer MQL5. Think of MQL5 as the newer generation—it gives programmers more tools to build faster, smarter and more efficient trading robots.
For most beginners, the programming language itself won’t matter unless you plan to create or modify your own Expert Advisors. However, because MQL5 is more powerful, many new automated trading systems are now being developed specifically for MT5.
| Feature | MQL4 | MQL5 |
|---|---|---|
| Ease of Learning | Simple | Slightly More Advanced |
| Performance | Good | Excellent |
| Future Development | Limited | Active |
Strategy Testing and Optimisation
One of MT5’s biggest advantages is its improved Strategy Tester. Before risking real money, traders usually test an Expert Advisor using historical market data. This process is known as backtesting.
MT5 performs these tests much faster than MT4, allowing traders to analyse years of historical data in a fraction of the time. It also offers more detailed reports, helping traders identify weaknesses before using an EA on a live account.
Why This Matters
Imagine testing 100 different versions of the same trading robot. If each test takes five minutes instead of twenty minutes, you could save many hours while developing or improving your strategy. Faster testing means faster learning.
Multi-Threaded Processing Explained
You may have seen the phrase “multi-threaded processing” in other MT5 reviews. It sounds complicated, but the idea is actually simple.
Think of your computer as having several workers available to complete a job. MT4 generally assigns one worker to process trading calculations, while MT5 can divide the work between several workers at the same time. This allows complex calculations and large backtests to finish much more quickly on modern computers.
Simple Example
Imagine asking one person to sort 10,000 trading records. It could take all afternoon.
Now imagine giving the same job to eight people working together. The task finishes much sooner because the workload is shared.
That’s essentially what MT5 does with many of its calculations—it uses more of your computer’s processing power to complete large tasks faster.
My Experience
When I first started experimenting with trading robots, MT4 was the industry standard and almost every Expert Advisor was written for it. Over time, however, I found myself using MT5 more often because strategy testing was noticeably faster and the platform continued to receive meaningful improvements.
Today I still understand and appreciate MT4, especially when working with older Expert Advisors, but if someone asked me which platform they should learn first, my answer would almost always be MT5 because it’s the platform most likely to support your trading for years to come.
When MT4 Is Still the Better Choice
After reading the previous sections, you might think MT5 is always the correct answer. In most cases it is—but there are still situations where choosing MT4 makes perfect sense. Thousands of traders continue to use MT4 successfully every day, and for some traders it remains the most practical option.
The key is understanding your own situation. The best platform isn’t always the newest one—it’s the one that works best for your trading goals and the tools you already own.
Choose MT4 If…
- ✅ You already own several MT4 Expert Advisors.
- ✅ Your trading strategy depends on older MQL4 software.
- ✅ Your broker only offers MetaTrader 4.
- ✅ You don’t intend writing or developing new trading robots.
- ✅ Your current MT4 setup is profitable and reliable.
Choose MT5 If…
- ✅ You’re completely new to automated trading.
- ✅ You want to build or purchase new Expert Advisors.
- ✅ You need faster backtesting and optimisation.
- ✅ You plan to trade more than just Forex.
- ✅ You want a platform that continues receiving major updates.
Should You Upgrade from MT4 to MT5?
This is probably the most common question traders ask. The answer depends entirely on where you are in your trading journey.
| Situation | Recommendation |
|---|---|
| I’m a complete beginner. | Start with MT5. |
| I already own several MT4 robots. | Continue using MT4 until you’re ready to migrate. |
| I’m learning algorithmic trading. | Choose MT5. |
| I only trade Forex manually. | Either platform will work well. |
| I’m building new Expert Advisors. | Definitely MT5. |
Common Myths About MT4 and MT5
❌ Myth: MT4 is obsolete.
Not true. MT4 is still used by millions of traders worldwide and remains an excellent platform for many existing Expert Advisors.
❌ Myth: MT5 is too complicated for beginners.
Also false. From a trader’s perspective, MT5 is just as easy to learn as MT4. Most of the additional complexity only affects programmers developing Expert Advisors.
❌ Myth: MT5 robots are always more profitable.
Profitability depends on the trading strategy—not the platform. A poor Expert Advisor will lose money on either platform, while a well-designed strategy can perform successfully on both.
❌ Myth: You must upgrade immediately.
No. If your existing MT4 setup works well, there is no need to rush. Many traders gradually move to MT5 as they replace or update their trading systems.
💡 Brian’s Practical Advice
I’ve used both MT4 and MT5 over the years, and I’ve learned that traders sometimes spend too much time worrying about the platform instead of improving their trading knowledge. The reality is that neither platform will make you profitable on its own.
Choose a reliable platform, learn it thoroughly, focus on building a solid trading strategy and practise disciplined risk management. Those factors will have a much bigger impact on your success than whether you click the MT4 or MT5 icon on your desktop.
Frequently Asked Questions
These are some of the most common questions beginners ask when choosing between MT4 and MT5 for Expert Advisors.
Can I run Expert Advisors on both MT4 and MT5?
Yes. Both platforms fully support automated trading through Expert Advisors. However, MT4 uses MQL4 while MT5 uses MQL5, meaning robots written for one platform usually cannot run directly on the other without being converted.
Can I use my MT4 Expert Advisors on MT5?
Not directly. Because the programming languages are different, MT4 Expert Advisors generally need to be rewritten or converted before they can run on MT5.
Is MT5 more difficult to learn?
No. From a trader’s perspective, MT5 feels very similar to MT4. Most of the additional features are aimed at developers and advanced users, so beginners usually adapt quickly.
Which platform do most brokers support?
Many brokers continue to offer both platforms. However, an increasing number of brokers now encourage new clients to use MT5 because it supports a wider range of financial markets and continues to receive regular improvements.
Does MT5 make trading robots more profitable?
No. The platform simply provides better tools and faster processing. Profitability depends on the quality of the trading strategy, sensible money management and proper testing—not the software itself.
Which platform would you recommend for someone starting today?
For almost every beginner, I recommend MT5. It is the platform MetaQuotes continues to develop, supports modern trading technology and offers better long-term flexibility for both manual and automated trading.

🏆 Final Verdict
If you’re starting from scratch in 2026, choose MetaTrader 5.
After comparing both platforms, MT5 is the stronger long-term choice for most traders. It offers faster strategy testing, improved performance, broader market support and continues to receive active development from MetaQuotes.
That doesn’t mean MT4 has become a poor platform. If you already own reliable MT4 Expert Advisors or your broker only supports MT4, there’s no urgent need to switch. Many experienced traders continue to use MT4 successfully every day.
The important point is to remember that your success will never depend solely on the platform you choose. Consistent profitability comes from developing a sound trading strategy, practising disciplined risk management and testing every Expert Advisor thoroughly before risking real money.
Choose the platform that fits your current needs, master it thoroughly and focus on becoming a better trader rather than chasing the latest technology.
