MT4 vs MT5: Which Platform Should You Actually Use in 2026?

If you are opening a trading account this year, the MT4 vs MT5 question comes up fast. Both platforms come from the same company, MetaQuotes. Both look almost the same when you open them. But they run on different code, and that choice affects your indicators, your trading robots, and how you test a strategy.

This guide gives you a straight answer. We compare the two platforms on the things that change your actual trading day: order types, timeframes, testing speed, and broker support. No hype. By the end, you will know which one fits how you trade.

What is the real difference between MT4 and MT5?

MT4 and MT5 are not two versions of the same software. MetaTrader 4 launched in 2005 and was built for currency trading. MetaTrader 5 arrived five years later as a multi-asset platform designed to reach stocks, futures and commodities as well as forex. They use different programming languages, so a tool built for one will not run on the other.

Here is how they compare on paper:

These figures come from MetaQuotes’ own platform comparison, which confirms the 21-versus-9 timeframe gap, 6 versus 4 pending order types, and the multi-threaded Strategy Tester in MetaTrader 5.

Is MT5 faster than MT4?

Yes, in the places that matter to system traders. MT5 runs on a 64-bit multi-threaded architecture, while MT4 is 32-bit. The biggest practical gain is backtesting. MT5 can use every core on your processor and test several instruments at once. On MT4, a long backtest runs on a single thread and can take hours.

For clicking a buy button, you will not feel a difference. Your broker’s execution speed matters far more than the platform.

Can you run MT4 indicators and EAs on MT5?

No. This is the single most important thing to understand. MT4 tools are written in MQL4. MT5 tools are written in MQL5. The two languages are close cousins but not compatible. An Expert Advisor built for MT4 must be rewritten before it will run on MT5.

If you have paid for a custom EA or rely on a set of custom indicators you have tuned over years, that rewrite is a real cost. It is the main reason experienced traders stay on MT4.

Is MT4 being discontinued?

Not officially, but the direction is clear. MetaQuotes ended active development of MT4 in early 2015 and stopped selling new MT4 licences in 2018, including extra servers for existing clients. The company continues to release security patches and bug fixes, but new features go into MT5 only. MT5 also passed MT4 in the number of brokers using it back in June 2021.

So MT4 still works, and thousands of brokers still offer it. But it is a frozen product. A new broker cannot buy an MT4 licence today, which means the pool of MT4 brokers can only shrink.

Which platform should you choose in 2026?

Choose MT4 if:

• You already own MQL4 tools you don’t want to rebuild
• You trade forex pairs only and want the simplest possible screen
• Your broker’s MT4 spreads or execution are better than its MT5 offering
• You follow a signal service that publishes MT4-specific settings

Choose MT5 if:

• You are opening your first account and starting fresh
• You want stocks, indices or crypto in the same terminal as your forex pairs
• You backtest seriously and need real-tick, multi-currency testing
• You want the built-in economic calendar and Depth of Market

If you are new to forex trading with no legacy tools, MT5 is the sensible default. You get more timeframes, better testing, and a platform that will still receive updates in five years.

A note for gold traders

If your focus is XAUUSD, MT5 has two small advantages. The extra intraday timeframes (M2, M3, M10, H2, H8) help when you are mapping structure across sessions, and Depth of Market gives you a rough sense of resting liquidity. Neither is essential — plenty of profitable traders run gold strategies on plain MT4 charts — but they are useful.

The practical answer

Most traders overthink this. The platform is a tool, not an edge. Your risk management, your entry rules and your choice of broker will decide your results far more than which MetaTrader version sits on your desktop.

That said: in 2026, if nothing is holding you to MT4, use MT5. It is the platform MetaQuotes is actually building. Most brokers let you open a demo on both, so spend a week on each before you commit real money. The mobile apps are worth testing too, since that is where many traders manage positions during the day.
