MT4 vs MT5: Which MetaTrader Version Wins for Prop Traders

What MT4 and MT5 Actually Are

MetaTrader 4 is a desktop trading platform developed by MetaQuotes Software and released in the mid-2000s. It was designed primarily for retail forex and CFD trading, ships with the MQL4 scripting language, and uses a hedging account model where multiple positions on the same symbol can coexist. MT4 became the de facto retail forex standard during the 2010s, with thousands of brokers and prop firms offering it as their default platform.

MetaTrader 5 was released by MetaQuotes a few years after MT4 as a ground-up rebuild rather than a version increment. It targets multi-asset trading (forex, CFDs, futures, stocks, and crypto where the broker supports them), exposes a full depth-of-market ladder, supports both hedging and netting account modes, and uses the redesigned MQL5 language. MetaQuotes stopped issuing new MT4 broker licenses around 2018, but the existing MT4 install base remains massive and fully supported.

For prop traders, the practical distinction is not which is newer but which one the firm offers. Forex-focused prop firms (FTMO, The 5%ers, FundedNext, Goat Funded Trader) typically support both, with a subset of plans on MT4 only or MT5 only. MT4 still wins on raw broker count and educational content; MT5 wins on order types, asset breadth, and modern features. Indicators and Expert Advisors written for one do not run on the other without a full rewrite.

Side-by-Side Specs: MT4 vs MT5

The table below summarises the headline differences. The two platforms share visual DNA, but the engine, language, and asset support diverge significantly under the hood.

Pricing and Licensing

Both MT4 and MT5 are free for end users. The cost sits on the broker or prop firm side: they license a server installation from MetaQuotes and pass the platform to traders at no charge. Traders download the client terminal directly from the broker's website or from MetaQuotes. There is no per-user subscription, no per-contract platform fee, and no premium tier from MetaQuotes itself.

Indirect costs come from third-party indicators, Expert Advisors, and VPS hosting. A serious MT4 or MT5 algorithmic trader typically rents a Forex VPS for around $20 to $40 per month to keep an EA running 24/5 next to the broker's data center. Paid indicators on the MQL5 marketplace range from a few dollars to a few hundred for sophisticated systems. Educational MT4 content is more plentiful than MT5 simply because MT4 has been around longer.

What Prop Firms Charge On Top

Prop firms typically wrap their own evaluation fee around the platform. FTMO, FundedNext, The 5%ers, and similar firms charge anywhere from around $80 for small accounts to several hundred dollars for $200K evaluations. The platform itself does not change that pricing. What does change is which version of MetaTrader you receive: some firms default to MT5 for new sign-ups, others let you choose MT4 vs MT5 at checkout.

Charting and Indicators

MT4 ships with around 30 standard technical indicators, classic chart types (line, bar, candlestick), and the ability to load custom indicators written in MQL4. The interface is dated by modern standards but reliable. Most paid forex indicators (smart money concepts, ICT tools, order block markers) are written for MT4 because of its longer install base.

MT5 expands the indicator library to around 38 built-in indicators, adds more timeframes for cleaner intraday analysis, and includes a built-in economic calendar inside the chart workspace. The chart rendering engine is faster on large data sets, and the multi-currency strategy tester is significantly more capable. MQL5 is closer to standard C++ and easier to develop more complex strategies in, though the syntax is unfamiliar to MQL4 veterans.

Indicator and EA Compatibility

This is the single most important practical difference. An indicator or Expert Advisor written for MT4 will not run on MT5, and vice versa. They use different languages, different APIs, and different account models. If you have a paid MT4 indicator suite or a working MT4 EA, switching to MT5 means either repurchasing the MT5 version (if available) or commissioning a port. Plan around your existing toolkit.

Order Types and Execution

MT4 supports market, limit, stop, and stop-limit orders, plus take-profit and stop-loss attached to positions. It does not support partial fills natively, which means orders are filled in full or not at all. The hedging account model lets traders hold long and short positions on the same instrument simultaneously, useful for some grid and martingale strategies.

MT5 adds two more pending order types (buy stop limit and sell stop limit), supports partial fills, and offers both hedging and netting account modes. The netting model aggregates all positions on a symbol into a single net position, which matches how most futures and stock exchanges report positions. For a futures-style trader, MT5 feels more natural; for a forex grid trader, MT4 hedging is often preferred.

Broker and Data-Feed Connectivity

MT4 connects to thousands of forex and CFD brokers worldwide. The MT4 server software is mature, widely supported, and runs in every major financial center. Bridges exist to connect MT4 to Interactive Brokers, Currenex, and some FCMs, though forex remains its center of gravity.

MT5 connects to a growing roster of brokers offering multi-asset accounts. Because MT5 includes Level 2 depth of market data natively, brokers that route to exchanges (futures, stocks) integrate more cleanly than they did with MT4. Crypto-friendly brokers (those offering BTC, ETH CFDs) have largely standardised on MT5 in recent years.

Prop Firm Support: Which Firms Offer Each

Both versions are well-supported across the forex prop firm ecosystem, with MT5 gaining ground in newer firm rollouts. The table below maps current platform availability at major prop firms. Always confirm during sign-up, since firms periodically deprecate one version on specific plans.

Why Futures Prop Firms Skip MetaTrader

US futures prop firms (Topstep, Apex, MyFunded Futures, Tradeify, Bulenox) do not offer MetaTrader at all. They route through NinjaTrader, Tradovate, TradingView, Sierra Chart, and Rithmic-based platforms instead. MetaTrader's home turf is forex and CFD prop firms, primarily operating outside the US futures regulatory framework.

Mobile Experience

Both MT4 and MT5 have native iOS and Android apps from MetaQuotes. They cover the basics: charting with standard indicators, order placement, position management, and account history. The mobile apps feel similar across both versions, and most retail traders cannot tell the difference. Mobile is suitable for trade monitoring and emergency closes, not for primary execution.

Neither mobile app supports custom indicators or Expert Advisors loaded from the desktop. If you rely on a custom MT4 indicator suite for entries, you cannot replicate that on your phone. This is universal across both versions and is rarely a deal-breaker since most prop firm traders execute from a desktop or laptop.

Strategy Testing and Automation

MT4's strategy tester is single-threaded and single-symbol. It works for testing a basic EA on one currency pair, but back-tests of multi-currency portfolios or tick-level high-frequency strategies are slow and limited. MQL4 is straightforward to learn for traders coming from any C-like language.

MT5's strategy tester is multi-threaded, multi-currency, and supports tick-level back-testing on real historical data. It is genuinely useful for serious quant work in a way MT4's tester is not. MQL5 is closer to modern C++ and gives developers cleaner OOP support, more standard library functions, and better debugging. If your edge is systematic, MT5 is the better engine.

Learning Curve and Community

MT4 has the larger community by orders of magnitude. Years of YouTube tutorials, written guides, paid courses, and free indicator libraries mean a new MT4 user finds an answer to almost any question within minutes. The MQL4 codebase on the MQL5 marketplace and GitHub is enormous.

MT5's community is smaller but more active and modern. Newer content tends to be MT5-first, particularly anything involving multi-asset trading or modern algorithmic techniques. For a complete beginner, MT4 is the lower-friction starting point because of sheer content volume; for a developer-track trader, MT5 is more future-proof.

Total Cost of Ownership Year One

Both versions have effectively the same cost profile. The biggest variable is how heavily you invest in indicators, EAs, and VPS hosting. Discretionary traders running stock indicators on one chart can use either platform completely free.

Quick-Reference Decision Matrix

The decision matrix below summarises which trader profile is better served by each version. The right answer depends on your asset focus, your tooling, and whether your prop firm even gives you a choice.

When MT4 Wins

• You already own a working library of paid MT4 indicators or EAs and do not want to rebuild
• Your prop firm only offers MT4, or your preferred plan is MT4-only
• You run grid, hedging, or martingale strategies that depend on the hedging account model
• You are a complete beginner and want the largest possible volume of tutorials and forums
• You only trade forex pairs and do not need multi-asset access

When MT5 Wins

• You trade or plan to trade multiple asset classes (forex plus stocks, indices, or crypto)
• You need depth-of-market data and Level 2 quotes natively
• You build systematic strategies and want a multi-threaded, multi-symbol back-tester
• You want partial fills, the netting account model, or the wider order type list
• You are starting fresh in late 2025 and want the modern, actively-developed platform

Migration Path: MT4 to MT5

Traders moving from MT4 to MT5 face three migration tasks. First, sourcing MT5 versions of any custom indicators or Expert Advisors, either by purchasing new licenses or commissioning ports from the original developers. Second, adjusting strategy logic to the netting account model if the broker provisions netting accounts rather than hedging. Third, relearning the strategy tester workflow, since MT5's multi-currency tester operates differently from MT4's single-symbol tester.

Most prop firms make migration easier by offering hedging-mode MT5 accounts, which behave nearly identically to MT4 for position management. The chart and workspace setup transfers conceptually but requires manual reconstruction. Budget a week of part-time effort to feel as fluid in MT5 as you were in MT4 after years of use.

Common Pitfalls Prop Traders Hit

The most common MT4 mistake on a prop evaluation is over-relying on hedging. Many forex prop firms count hedged positions as separate trades that each consume daily risk, and the apparent reduction in exposure can mislead traders into thinking they are flat when their risk is still active. Read the firm's hedging rules carefully before deploying grid strategies.

The most common MT5 mistake is assuming MT4 indicators will load. They will not. If you switch to MT5 you need to source MT5-native versions of every custom tool you use. The second-most-common MT5 mistake is confusion between hedging and netting modes: a netting account aggregates positions, so a second buy order extends the existing long rather than opening a new ticket, which surprises traders coming from MT4.

Reliability and Server Stability

MT4 has had two decades to harden. Server crashes are rare, the protocol is well-understood, and broker IT teams have deep experience managing the infrastructure. The desktop client is light and runs reliably on modest Windows machines. Most platform-side incidents trace back to the broker's server rather than MetaQuotes software itself.

MT5 is newer but has been in production for more than a decade and is similarly stable. The richer feature set means a slightly heavier client, but the difference is invisible on any modern laptop. Both platforms benefit from running on a dedicated VPS for algorithmic traders who need 24/5 uptime without local machine interruptions.

Integration With Third-Party Tools

MT4 integrates with TradingView via paid webhook bridges, with copy-trade services like Myfxbook AutoTrade, ZuluTrade, and Signal Start, and with trade journals like FX Blue, MyFXBook, and TraderVue. The bridge ecosystem is mature. Most third-party trading services list MT4 support as their default.

MT5 increasingly supports the same third-party tools, with copy-trading networks and journal services gradually adding MT5 connectors. The MQL5 marketplace also serves as a built-in store for indicators, EAs, and copy-trade signals directly from inside the platform, which gives MT5 an integrated commerce advantage MT4 lacks.

Verdict for Prop Traders

Choose MT4 if your prop firm and your tooling already revolve around it, if you trade forex exclusively, or if you depend on hedging-account behavior. Choose MT5 if you are starting fresh, plan to trade multiple asset classes, want modern back-testing, or value the wider order types and depth-of-market data. Both are free, both work at the major forex prop firms, and both have native mobile apps. The choice is rarely critical; it is more about ecosystem fit than raw capability.

Bottom Line

MT4 and MT5 are sister platforms from the same vendor that solve overlapping but distinct problems. MT4 is the older, forex-anchored, hedging-first standard with the largest community and the deepest legacy indicator library. MT5 is the newer, multi-asset, netting-capable, deeper-tested platform that most new brokers default to. For prop traders, the version usually picks itself based on the firm's offering. If you have a free choice, lean MT5 for forward-looking flexibility and lean MT4 if your existing toolkit and prop firm anchor you there.

Frequently Asked Questions

Is MT5 just a newer version of MT4?

No. Despite the version number, MT5 is a ground-up rebuild rather than an upgrade. It uses a different scripting language (MQL5 vs MQL4), supports more asset classes, and uses a different account model. Indicators and Expert Advisors do not transfer between them, so switching is closer to changing platforms than upgrading software.

Which is better for forex trading?

MT4 has a slight edge for pure forex because of its hedging account model, deeper library of forex-specific indicators, and larger forex-focused community. Most retail forex traders and forex prop firms still default to MT4. MT5 works fine for forex and adds depth of market, but the ecosystem advantage on forex still leans MT4.

Which prop firms offer MT4 vs MT5?

Major forex prop firms including FTMO, FundedNext, The 5%ers, Goat Funded Trader, FundingPips, and E8 Markets all support both MT4 and MT5. Plan availability varies, so confirm at sign-up. US futures prop firms like Topstep, Apex, MyFunded Futures, and Tradeify do not offer MetaTrader in either version.

Can I run my MT4 Expert Advisor on MT5?

No. An EA written in MQL4 will not run on MT5 because the languages, APIs, and account models differ. You either need to source an MT5-native version of the same EA or pay a developer to port it. Budget at least a few hundred dollars for a competent port of a complex system.

Is MT4 being phased out?

MetaQuotes stopped issuing new MT4 broker licenses around 2018, but existing installations remain fully supported and the platform is still widely available. Reports of an imminent shutdown are exaggerated. MT4 will likely keep running for years; new development at MetaQuotes is MT5-focused.

Does MT5 support hedging?

Yes, but only if the broker enables hedging mode on the account. MT5 supports both hedging and netting account models, set at the server level by the broker. Many forex brokers offer MT5 hedging accounts to make migration from MT4 simpler. Confirm the account type before assuming hedging is available.

Which is faster?

MT5 has the faster engine, particularly for chart rendering on large data sets and for multi-currency, multi-threaded strategy back-testing. For discretionary trading on a few charts, the speed difference is imperceptible. For systematic work involving heavy back-tests or thousands of bars, MT5 is meaningfully faster.

Can I use both on the same account?

Generally no. A trading account is provisioned on either an MT4 server or an MT5 server by the broker, not both. Some brokers offer parallel accounts under one client login, letting you operate an MT4 account and an MT5 account side by side. Prop firms typically lock you to whichever version your plan was purchased on.

Are MT4 and MT5 free?

Yes, both are free for end users. You download the client terminal from your broker or directly from MetaQuotes at no cost. Brokers cover the licensing fee with MetaQuotes. Indirect costs (paid indicators, EAs, VPS hosting) are optional and vary by trader.

What is the biggest difference between MQL4 and MQL5?

MQL4 is closer to a simplified C dialect, easier for beginners but limited for complex projects. MQL5 is closer to modern C++ with proper object-oriented features, a richer standard library, and better debugging. Algorithmic developers find MQL5 more productive; quick-script writers often find MQL4 faster to draft.

Does MT5 work for futures and stocks?

Yes, where the broker supports those assets. MT5 was designed for multi-asset access and integrates futures and stock exchange feeds more cleanly than MT4. The catch is that few US-regulated futures brokers offer MetaTrader at all, so MT5 multi-asset is mostly relevant outside the US futures market.

Which has a better mobile app?

The mobile apps for MT4 and MT5 are functionally similar. Both cover charting, order placement, position management, and account history on iOS and Android. Neither runs custom indicators or EAs. Most traders cannot tell them apart day to day, so mobile is not a meaningful tie-breaker.

Should beginners start with MT4 or MT5?

Beginners benefit from MT4's larger volume of tutorials, free indicators, and community content. The learning curve is also gentler because the platform is simpler. Once comfortable, traders can graduate to MT5 if their strategy needs multi-asset access or modern back-testing. Many beginners never need to switch.

Is depth of market important?

For forex spot trading the depth of market is mostly cosmetic since spot FX is an OTC market and the displayed depth reflects the broker's aggregated feed rather than a true central order book. For futures and stocks routed through MT5, depth of market is genuine exchange data and useful for order-flow trading. Importance depends on asset class.

Will MT4 be supported in five years?

Almost certainly yes. The install base is too large for MetaQuotes or brokers to drop support abruptly. New broker licenses are no longer issued, but existing servers continue to operate. Plan for MT4 to remain viable for years; plan also for new feature development to remain MT5-focused.
