MT4 vs MT5: What's the Difference?

MetaTrader 4 and MetaTrader 5 share a name, a maker, and a family resemblance — which is exactly why people assume MT5 is just MT4 with a higher number. It isn't. They were built for different jobs, and the difference matters more than the version number suggests.

Both come from MetaQuotes. MT4 arrived first and became the default standard for retail forex. MT5 is the multi-asset successor, designed to reach beyond forex into other markets. Here's how that plays out.

Asset scope: specialist vs generalist

MT4 is a forex specialist. It was designed around currency pairs and a limited set of CFDs, and that focus is part of why it stayed so popular — it does the one job well.

MT5 is a generalist. It was built to handle forex plus other asset classes like stocks, indices, commodities, and futures contracts. If you ever want to trade beyond pure forex on a MetaTrader platform, MT5 is the one with the wider reach — though what you can actually access still depends on your broker.

Automation: MQL4 vs MQL5

This is the deepest split, and it's not backward-compatible. MT4 automation is written in MQL4; MT5 uses MQL5. They are different languages, so an Expert Advisor or custom indicator built for MT4 will not simply run on MT5, and vice versa.

That single fact explains a lot of the market's inertia. Traders who spent years building or buying MT4 tools face a real choice: rebuild for MT5 or stay put. MQL5 is the more capable language — object-oriented, better at multi-instrument logic, with faster multi-threaded backtesting — but "more capable" doesn't help if your existing library only speaks MQL4.

Tools and interface

MT5 simply has more built in: more native timeframes, more bundled indicators, and a native economic calendar that MT4 lacks. MT4's interface is older and more sparse. Neither is hard to learn, but MT5 gives you more out of the box, while MT4 leans on its enormous community library of add-ons to fill gaps.

That community library is worth dwelling on, because it's the quiet reason MT4 refuses to die. Years of forums, vendors, and traders have produced a vast catalog of MT4 indicators and EAs. For someone whose whole approach is wired into one of those tools, the "older" platform isn't a downgrade — it's the only place their setup runs without a rebuild.

Why MT5 leads in prop trading

In the funded-trading world, MT5 has become the more common offering — a large majority of newer firms lean toward it, partly because traders ask for its broader features and faster backtesting. MT4 hasn't vanished, though. Many firms run both, letting forex purists stay on MT4 while others use MT5. If prop firms are new to you, start with what is a prop firm and prop firm vs broker.

So which mindset fits which?

If you have a working MT4 EA or a habit built on MT4 tools, MT4's pull is real and practical. If you're starting fresh, want broader asset scope, or value faster backtesting and a richer default toolset, MT5 is the forward-looking choice. Neither is "right" in the abstract — it depends on what you carry into it.

Both, of course, are just two stops on a larger map. To see where they sit next to newer tools, read TradeLocker vs MetaTrader 5 and the platform map. And if you're still building fundamentals, our School of Stewardship Trading starts from the basics.
