MetaTrader 5 vs MetaTrader 4: Which Forex Platform Should You Choose?

The MT4 vs MT5 Debate That Won't Die

Walk into any Forex trading forum, and you'll see the same argument playing out. Traders defending MT4 like it's their religion, traders claiming MT5 is the only rational choice, and a whole lot of confused beginners wondering what the actual difference is.

Here's the reality: both platforms work. Traders make money on both. Traders blow up accounts on both. The platform itself isn't what determines your success. But choosing the right one for your trading style matters. MT4 and MT5 have real differences that affect your daily trading experience, your strategy options, and even which brokers you can use.

This article cuts through the fanboyism and gives you a practical breakdown. I'll explain what each platform actually does well, where they fall short, and how to decide which one belongs on your desktop.

The Origin Story: Why Two Platforms Exist

Before we dive into features, understand why MetaQuotes created MT5 in the first place. MT4 launched in 2005 and became the dominant Forex platform through sheer inertia. It was everywhere, brokers loved it, traders built their businesses around it. But MT4 had a problem—it was built specifically for Forex. The underlying architecture couldn't handle other markets properly.

MT5 launched in 2010 as a multi-asset platform. Stocks, futures, Forex, crypto—all from one interface. MetaQuotes wanted to create a platform that could do everything, not just currency trading. But here's the irony: the Forex community largely rejected MT5 and stuck with MT4. Traders were comfortable, their indicators and EAs were built for MQL4, and they didn't see the point in switching.

More than a decade later, we're still having this debate. MT4 remains the most popular Forex platform. MT5 has gained ground, especially among brokers who want to offer multi-asset trading. Neither is going away anytime soon.

Core Architecture Differences That Actually Matter

The difference between MT4 and MT5 isn't just cosmetic—under the hood, they're fundamentally different systems.

Order execution policy: MT4 uses last-in-first-out (FIFO) by default, though many brokers implement workarounds. MT5 enforces FIFO strictly because of regulatory requirements in some jurisdictions. This matters if you scale into positions. In MT4, you could have multiple positions in the same pair at different entry prices. MT5 consolidates them into a single position with an average price. Some traders love this, some hate it. Know your preference.

Market depth: MT5 offers DOM (Depth of Market) visualization showing available liquidity at different price levels. MT4 doesn't have this built-in. If you trade based on order flow or want to see where the liquidity is, MT5 has the edge. For most retail Forex traders who don't care about order book depth, this doesn't matter.

Hedging capability: When MT5 first launched, it didn't allow hedging (holding simultaneous long and short positions in the same instrument). Traders revolted. MetaQuotes eventually added hedging support to MT5, but it required brokers to enable it. Not all brokers do. Check with your broker if hedging matters to your strategy.

Timeframes and charts: MT4 tops out at 9 timeframes. MT5 offers 21 timeframes including more granular options and the ability to customize timeframes. If you're obsessed with analyzing M2 or M6 charts, MT5 has you covered. For most traders, the standard MT4 timeframes are plenty.

Technical indicators: MT4 comes with 30 built-in indicators. MT5 has 38 built-in indicators plus the ability to combine multiple timeframes on a single chart. If you're an indicator junkie, MT5 offers more out-of-the-box power.

Programming Languages: MQL4 vs MQL5

This is where the platforms diverge most significantly for traders who develop their own tools.

MQL4 (MT4): Simpler, easier to learn, more forgiving syntax. If you have basic programming knowledge, you can knock out a basic EA or indicator in MQL4 over a weekend. The language was designed for traders, not computer scientists. There's a massive library of existing MQL4 code—thousands of free indicators and EAs are available online. The community has been building MQL4 tools for nearly 20 years.

MQL5 (MT5): More powerful, more complex, object-oriented programming. If you know C++ or Java, MQL5 will feel familiar. If you don't, there's a steeper learning curve. MQL5 can handle more complex calculations, process data faster, and create more sophisticated indicators. But you pay for that power with complexity.

Code compatibility: This is the pain point. MQL4 code doesn't run on MT5. MQL5 code doesn't run on MT4. There's no simple converter that works reliably. If you've built your trading system around custom MQL4 EAs, migrating to MT5 means rewriting everything from scratch. This is why many traders refuse to switch—the switching cost is too high.

Speed and performance: MT5 executes code faster than MT4. For most traders, this difference is imperceptible. Your typical EA doesn't need that kind of processing power. But if you're running complex calculations, backtesting massive datasets, or running dozens of indicators simultaneously, MT5's performance advantage becomes real.

Backtesting: MT5's Strategy Tester is significantly more powerful. You can test EAs across multiple currency pairs simultaneously. You can test multi-currency strategies. The optimization algorithms are better. If backtesting is central to your strategy development, MT5 has clear advantages.

The Broker Reality: Availability Dictates Choice

Here's the practical truth that most comparison articles ignore: you can only use what your broker offers. And brokers are all over the map on this.

Some brokers offer only MT4. They've built their infrastructure around it, their clients use it, and they have no incentive to switch.

Some brokers offer only MT5. These are often brokers who focus on multi-asset trading or who want to future-proof their technology.

Many brokers offer both. They'll let you choose when you open an account.

Platform migration: Some brokers have actively migrated clients from MT4 to MT5. They might stop supporting MT4 for new accounts, or eventually phase it out entirely. If your broker pushes you toward MT5, there's often a reason—technology, regulatory compliance, or cost.

Account types: Here's something that catches people: some brokers offer different trading conditions depending on which platform you use. Same broker, same account type, but spreads or commissions might differ between MT4 and MT5. Always check the specific conditions for the platform you're choosing.

Regulatory considerations: Some jurisdictions have moved toward MT5 because of its FIFO enforcement and more compliant order handling. If you're trading through a regulated entity in certain regions, you might not have a choice—MT5 could be mandatory.

Market Access: Forex vs Multi-Asset

MT4 was built for Forex. It handles currency pairs brilliantly. It doesn't really do anything else.

MT5 was built for everything. Forex, stocks, stock indices, futures, crypto, commodities—one platform, all markets.

The Forex-only trader: If you only trade Forex, you don't strictly need MT5. MT4 does everything you need. You can analyze pairs, execute trades, run EAs, manage risk. MT5 doesn't offer magical advantages for pure Forex trading that justify switching if you're already comfortable with MT4.

The multi-asset trader: If you trade Forex and stocks and futures, MT5 becomes compelling. Managing multiple platforms across different asset classes is annoying. MT5 consolidates everything in one place. You can switch between EUR/USD and Apple stock and crude oil futures without changing platforms.

The crossover trader: You might not trade multiple asset classes now, but what about two years from now? If there's any chance you'll expand beyond Forex, MT5 gives you room to grow without learning a new platform later. Starting with MT5 even for pure Forex isn't a bad move if you think your trading might evolve.

Interface and Usability: What You Actually Experience

Most traders spend hours staring at their trading platform. The user experience matters.

MT4 interface: Familiar, straightforward, Windows 98 aesthetic that hasn't aged gracefully. But it works. Everything is where you expect it to be if you've used any trading platform before. The learning curve is minimal. You can figure out 90% of MT4's features in an afternoon.

MT5 interface: More modern, more customizable, slightly more complex. There are more menus, more options, more things to click. This can be overwhelming for beginners but powerful once you know what you're doing. You can customize workspaces, save different chart layouts, and organize your screen more efficiently.

Chart capabilities: MT5 allows you to open up to 100 charts per window (MT4 allows fewer, though most traders never hit that limit). MT5 has better built-in charting tools—more drawing objects, more sophisticated technical analysis tools. If you're a heavy chart user, MT5's capabilities are genuinely better.

Mobile apps: Both MT4 and MT5 have mobile versions. They're similar in functionality. If you switch between desktop and mobile frequently, the transition is seamless on both platforms. Neither has a significant mobile advantage.

Performance and Reliability: Speed Matters

When you're in a trade and need to exit, milliseconds can feel like hours.

Execution speed: MT5 is faster. The architecture is more efficient, order processing is quicker. For most traders, the difference is negligible—you're not high-frequency trading, and your broker's infrastructure matters more than the platform software. But if you're a scalper trading news events, every bit of speed counts.

Resource usage: MT5 is more resource-intensive. It uses more RAM and more CPU power. On a modern computer, you won't notice. If you're trading on an older laptop or running multiple platforms simultaneously, MT4 runs lighter.

Stability: Both platforms are mature and stable. Crashes are rare on either platform assuming your hardware meets basic requirements. MT5's newer codebase should theoretically be more stable, but MT4 has been battle-tested for nearly two decades. Both are reliable enough that platform stability shouldn't drive your decision.

Data feeds: MT5 handles more data types and higher data volumes. If you're a data nerd who wants tick-by-tick historical data going back years, MT5's data handling is superior. For most traders who just need daily or hourly price data, both platforms are adequate.

Community and Resources: The Ecosystem Effect

Trading platforms are ecosystems. The value comes partly from what the platform does, partly from what the community has built around it.

MT4 community advantage: There are millions of MT4 users. That means thousands of free indicators, hundreds of free EAs, countless YouTube tutorials, forum threads answering every possible question. If you have a problem with MT4, someone has solved it already. The Code Base at MQL4.com has over 10,000 free applications you can download in seconds.

MT5 community growth: The MT5 community is smaller but growing. Many new developments are happening on MT5, especially from institutional developers who need MT5's advanced capabilities. The gap is narrowing, but MT4 still has a massive head start in community resources.

Paid products: The MetaTrader Market sells indicators, EAs, and trading tools for both platforms. MT4 has more products available, but MT5 is catching up. If you're planning to purchase trading tools, check availability on your preferred platform before committing.

Learning resources: YouTube has endless MT4 tutorials. MT5 tutorials are less common but increasing. If you're a visual learner who likes video content, MT4 has a advantage in the quantity and variety of learning materials.

Forum support: The MQL5 forum (which covers both platforms) is active and helpful. Questions get answered. Problems get solved. Neither platform leaves you stranded for support.

Cost Considerations: Is One Platform Cheaper?

This often surprises traders: the platform itself is free. You don't pay MetaQuotes to use MT4 or MT5. The broker pays MetaQuotes, and they make their money back through spreads, commissions, and swap fees.

But there are hidden costs:

VPS hosting: If you run EAs 24/7, you need a VPS. Some brokers offer free VPS hosting for MT4 or MT5 accounts that meet minimum trading volume requirements. Check whether your broker's free VPS supports your preferred platform.

EAs and indicators: Some paid tools are platform-specific. If you buy an MT4 EA and later decide to switch to MT5, you'll need to buy the MT5 version. Some developers charge separately for each platform.

Data feeds: Advanced data services might charge differently for MT4 vs MT5 feeds. If you're using premium data sources, check platform compatibility and pricing.

Commission structures: As mentioned earlier, some brokers offer different commission structures depending on platform. This is broker-specific, not platform-specific, but it affects your real trading costs. Always check the trading conditions for your specific platform and broker combination.

Who Should Choose MT4?

MT4 makes sense if:

You're a beginner: The learning curve is gentler. There are more tutorials, more free resources, more people to help you. You can focus on learning to trade rather than wrestling with platform complexity.

You only trade Forex: MT4 handles Forex trading perfectly well. You don't need MT5's multi-asset capabilities. The extra features would just be clutter you never use.

You rely on MQL4 tools: If you've built your trading system around MQL4 EAs and indicators, switching to MT5 means rewriting code. That's a real cost in time and potential bugs. Stay with MT4 unless there's a compelling reason to switch.

You want maximum community resources: The MT4 ecosystem is unmatched. Free indicators, free EAs, endless tutorials. If you're the type who likes to experiment with different tools, MT4 gives you more to play with.

You prefer simplicity: MT4 does fewer things than MT5, but what it does, it does simply. If you want a trading platform that gets out of the way and lets you trade, MT4's minimalist approach has appeal.

Who Should Choose MT5?

MT5 makes sense if:

You trade multiple asset classes: Forex plus stocks plus futures? MT5 lets you manage everything from one platform. That convenience becomes real when you're actually juggling different markets.

You're a serious algorithmic trader: MQL5 is more powerful, MT5's backtesting is superior, the Strategy Tester handles multi-currency optimization. If trading system development is your focus, MT5's technical advantages matter.

You're starting fresh: If you're new to trading and haven't built up an ecosystem of tools on either platform, starting with MT5 positions you for the future. The learning curve is slightly steeper, but you're learning the more modern, more capable platform from day one.

You need advanced execution features: If FIFO order handling matters to you, if you want market depth visualization, if you need more sophisticated order types, MT5 has capabilities that MT4 simply doesn't offer.

You want future-proofing: MT5 is where MetaQuotes is investing development resources. MT4 is in maintenance mode—still supported, but not evolving. Long-term, MT5 is the platform with a roadmap.

The Migration Dilemma: Should You Switch?

For traders already using MT4, this is the real question. And there's no universal answer.

When to stay with MT4:

Your current system works well
You have custom MQL4 tools that would need rewriting
Your broker offers better conditions on MT4
You only trade Forex
You're profitable and don't want to mess with success

When to consider switching to MT5:

You're expanding into stocks or futures
Your broker is phasing out MT4
You need features MT4 can't provide
You're starting from scratch with a new trading system
You want access to more advanced backtesting and optimization

The hybrid approach: Some traders run both platforms. MT4 for existing systems and tools, MT5 for new development or multi-asset trading. It's not ideal—managing two platforms is annoying—but it lets you migrate gradually rather than all at once.

Trading Styles: Which Platform Suits Your Approach?

Different trading styles place different demands on your platform. Here's how MT4 and MT5 align with various approaches.

Scalping: If you're a scalper making dozens of trades per day, execution speed matters. MT5 has the edge here—faster order processing, more efficient use of resources. Scalpers also appreciate MT5's Market Depth feature, showing liquidity at different price levels. But here's the reality: if your broker has slow execution, the platform won't save you. A fast platform on a slow broker still yields slow fills. For scalpers, broker selection matters more than platform choice.

Day trading: Day traders need reliable execution and solid charting. Both platforms handle this well. MT5's additional timeframes might be useful if you're analyzing M5 or M15 charts with M2 context. But most day traders find MT4's nine timeframes sufficient. The decision comes down to personal preference and what you're used to.

Swing trading: Swing traders hold positions for days to weeks. You don't need millisecond execution or complex order types. MT4 is perfectly adequate. You're not running complex algorithms, you're not backtesting intensively. You're analyzing charts, placing trades, managing risk. MT4 does this simply and effectively. Many swing traders see no reason to switch to MT5.

Algorithmic trading: This is where MT5 shines. If you're developing EAs, backtesting strategies, optimizing parameters, MT5's capabilities are superior. The Strategy Tester alone is worth the migration. Multi-currency backtesting, genetic optimization, faster execution—these matter when you're running automated systems. Serious algo traders gravitate toward MT5.

Position trading: Long-term traders who hold positions for months don't need advanced features. You're analyzing weekly or daily charts, making a handful of trades per year. MT4 is more than sufficient. The ecosystem advantage matters more—MT4 has more long-term traders sharing strategies, more indicators suited for swing and position trading.

Copy trading: If you're copying signal providers, the platform they use dictates your choice. Many signal providers still use MT4. Some have migrated to MT5. You go where the signals you want to follow are. The platform itself is secondary to the strategy you're copying.

News trading: Trading economic releases requires fast execution and reliable order placement. MT5's architecture handles the order flow spikes around news better. But again, broker execution quality matters more than platform software. A great platform on a broker with slippage during news won't help you.

Carry trade: Long-term currency traders earning interest differentials don't need complex platform features. MT4 handles carry trading perfectly—swap rates are visible, position management is straightforward, long-term charting works fine. No compelling reason to switch to MT5 unless you want to analyze other asset classes alongside your carry positions.

Price action trading: If you trade based on candlestick patterns and support/resistance, you want clean charts and drawing tools. Both platforms deliver here. MT5 has more drawing objects, but most price action traders use a handful of tools at most. The difference is negligible. Choose based on which interface you prefer.

Testing Both: The Only Way to Know for Sure

Reading about platforms helps. Actually using them tells you what you need to know.

If your broker offers both MT4 and MT5, download each. Open demo accounts. Spend a week trading on each. Place trades, draw charts, set up indicators, run backtests. You'll quickly develop a preference based on actual experience, not theoretical features.

Pay attention to:

How intuitive does the interface feel?
Can you find the features you use most without digging through menus?
Does the charting tools match how you like to analyze markets?
How fast do orders execute during volatile conditions?
Can you easily customize workspaces to your liking?

The "best" platform is the one that disappears when you're trading—the tool that helps you execute your strategy without getting in the way. For some traders, that's MT4. For others, it's MT5. You won't know until you try both.

The Bottom Line

The MT4 vs MT5 debate generates way more heat than light. Both are capable platforms. Successful traders use both. Unsuccessful traders use both. The platform is a tool, not a strategy, not a system, not a path to profitability.

Choose MT4 if you want simplicity, a massive community, and you focus purely on Forex. The ecosystem is unmatched, the learning curve is gentle, and it does everything most Forex traders need.

Choose MT5 if you want multi-asset access, advanced backtesting, and future-proof technology. It's more powerful and more capable, but also more complex and requires more learning investment.

The real question isn't which platform is objectively better. The question is which platform fits your trading, your goals, and your preferences. Answer that, and the MT4 vs MT5 decision solves itself.
