MT4 vs MT5: What Are the Differences and Which to Choose in 2026?

MetaTrader 4 and MetaTrader 5: two generations

MetaTrader 4 (MT4) was launched in 2005 by MetaQuotes Software. It quickly became the go-to platform for retail forex trading thanks to its intuitive interface, MQL4 programming language and vast developer community. For over 15 years, MT4 dominated the market with no real competitor.

MetaTrader 5 (MT5) was launched in 2010 as the successor to MT4. Despite what the name suggests, MT5 is not simply an upgrade of MT4. It is an entirely redesigned platform, built for financial markets broadly and not just forex. MT5 took time to gain traction, but by 2026, the majority of brokers have adopted it as their primary platform.

It is important to understand that MT4 and MT5 are not compatible with each other. Indicators, robots (EAs) and scripts written for MT4 do not work directly on MT5. This incompatibility slowed MT5 adoption for years, as many traders had invested in MQL4 tools they did not want to rewrite.

Key differences between MT4 and MT5

Timeframes. MT4 offers 9 time units: M1, M5, M15, M30, H1, H4, D1, W1 and MN. MT5 offers 21, adding M2, M3, M4, M6, M10, M12, M20, H2, H3, H6, H8 and H12. These additional timeframes enable far more granular technical analysis and accommodate a wider range of trading strategies.

Order types. MT4 offers 4 pending order types: Buy Limit, Sell Limit, Buy Stop and Sell Stop. MT5 adds two more: Buy Stop Limit and Sell Stop Limit. These hybrid orders allow you to place a limit order that only activates after a stop level is triggered, providing extra flexibility for breakout strategies.

Depth of Market (DOM). MT5 integrates an order book (Depth of Market) that displays bid and ask prices with available volumes at each level. This tool is absent from MT4. Depth of market is especially useful for traders who analyze order flow and available liquidity before entering a position.

Economic calendar. MT5 includes an economic calendar directly in the platform, showing upcoming macroeconomic events and their expected impact. On MT4, traders must use external websites or third-party plugins to access this information.

MQL4 vs MQL5: which language to choose?

The choice between MQL4 and MQL5 is often the decisive factor for traders who use trading robots (Expert Advisors) or custom indicators.

MQL4 is a procedural language that is simpler to learn. It was designed specifically for forex trading and has a massive existing code base. Thousands of free and paid robots and indicators are available in the MQL4 community. Its syntax is close to C and remains accessible to beginner programmers.

MQL5 is an object-oriented language, more powerful and flexible than MQL4. It allows the creation of more complex programs with better code structuring. MQL5 supports classes, interfaces and inheritance. The MQL5 strategy tester is multi-threaded, which dramatically speeds up backtesting. A backtest that takes 10 minutes on MT4 can be completed in 1 to 2 minutes on MT5.

The MQL5 ecosystem is gradually catching up with MQL4. The MQL5 marketplace offers an increasing number of robots and indicators. Developers can now sell their creations directly on the MetaTrader platform. By 2026, the MQL5 community is mature enough to meet the needs of most traders.

When to choose MT4 and when to choose MT5

Choose MT4 if:

• You own irreplaceable MQL4 robots or indicators that you cannot rewrite.
• Your broker only offers MT4 (increasingly rare in 2026).
• You trade exclusively forex with simple strategies.
• You are accustomed to the MT4 interface and do not need additional features.

Choose MT5 if:

• You want access to multiple markets (forex, indices, commodities, stocks, crypto).
• You need additional timeframes for your technical analysis.
• You are developing new robots and prefer an object-oriented language.
• You want faster backtesting with the multi-threaded strategy tester.
• You want built-in depth of market and economic calendar.
• You are looking for an actively developed, future-proof platform.

RaiseFX chose MT5 to offer its clients the most complete platform available. Headquartered in Johannesburg, South Africa and regulated by the FSCA (licence #50506), RaiseFX provides over 500 instruments with leverage up to 1:500 on MT5. The depth of market and 21 timeframes on MT5 give RaiseFX traders optimal analytical granularity.

In 2026, the trend is clearly in favour of MT5. MetaQuotes has stopped issuing new MT4 licences to brokers. Brokers that still offer MT4 do so for existing accounts, but direct new account openings toward MT5. For a trader starting out or switching platforms, MT5 is the most logical and future-proof choice.

Migrating from MT4 to MT5: what to know

Migrating from MT4 to MT5 requires an adjustment period. Here are the key points to anticipate.

The interface. MT5 has a slightly different interface from MT4, but the fundamentals remain the same: charts, symbol lists, trading terminal and strategy tester. The learning curve is quick for existing MT4 users. Some menus and options have moved, but the overall logic is identical.

Indicators and EAs. This is the most critical point. All MQL4 indicators and robots must be rewritten in MQL5. Automatic conversion tools exist, but they do not cover every case and manual review is often necessary. For traders who rely heavily on custom tools, a gradual migration is recommended. Test each converted tool on a demo account before using it live.

Trading history. Your MT4 trade history will not automatically transfer to MT5. Each platform manages its own history. Export your MT4 trading reports before migrating if you need to preserve this data.

Keyboard shortcuts. Most keyboard shortcuts are identical between MT4 and MT5. A few new shortcuts have been added in MT5 for additional features like quick access to depth of market or the economic calendar.

The migration is a time investment justified by gains in functionality and longevity. MT5 is the platform of the present and future of retail trading.
