If you’re launching a brokerage or reviewing your current setup, the platform question comes up early. And for most brokers, it narrows down to two names from the same company. MetaQuotes released MetaTrader 4 in 2005 and MetaTrader 5 about five years later. Both are still widely used, but they were built for different jobs, and the gap between them matters more on the broker side than most traders realise.
This guide looks at MT4 vs MT5 from a broker’s point of view. Not just which charts look nicer, but what each one means for your server setup, your product range, your risk handling and your long-term costs.
A Quick Bit of Background
MT4 was designed purely for retail forex. It did that job so well that it became the industry default for over a decade. A whole ecosystem grew around it: indicators, Expert Advisors, bridges, plugins and copy trading tools.
MT5 was not simply an upgrade. MetaQuotes rebuilt it to handle multiple asset classes, including exchange-traded instruments like stocks and futures. That broader scope is why it felt clunky to some forex traders at first, and also why it has aged better.
The bigger shift came when MetaQuotes stopped issuing new MT4 server licences. For a new broker today, getting a fresh MT4 setup usually means a white label through an existing licence holder, not a licence of your own.
Trading Features Your Clients Will Notice
Timeframes and Analysis Tools
MT4 offers 9 timeframes. MT5 offers 21, including options like 2-minute, 3-hour and 6-hour charts. MT5 also ships with more built-in indicators and graphical objects, plus an integrated economic calendar. For active traders, it’s a noticeably richer workspace without installing anything extra.
Order Types
MT4 has four pending order types. MT5 adds two more, Buy Stop Limit and Sell Stop Limit, which give traders more control over entries during breakouts. It’s a small change on paper, but experienced traders do ask for it.
Depth of Market
MT5 includes a Depth of Market window showing available liquidity at different price levels. MT4 doesn’t have this natively. If you’re targeting more professional traders or offering exchange-traded products, DOM is close to essential.
Expert Advisors and Coding Language
This is where MT4 still holds ground. Its MQL4 library is enormous, and plenty of traders run EAs they’ve used for years. MT5 runs on MQL5, and the two are not directly compatible. An MT4 EA has to be rewritten, not just copied across.
On the flip side, MT5’s strategy tester is far stronger. It’s multi-threaded, supports multi-currency testing and can use real tick data. Algo traders who’ve tried it rarely want to go back.
What Changes on the Operations Side
This is the part brokers care about most, and the part traders never see.
Asset Coverage
MT4 is built around forex and CFDs. You can add metals, indices and commodities as CFDs, but the platform was never meant for real exchange instruments. MT5 handles forex, CFDs, stocks, futures and options on one server. If your roadmap includes anything beyond FX in the next few years, that matters a lot.
Hedging and Netting
MT4 uses a hedging model only, meaning clients can hold buy and sell positions on the same symbol at once. MT5 supports both hedging and netting. Netting is required in some regulated markets and for exchange-style trading, so MT5 gives you more flexibility with regulators and products.
Server Architecture and Performance
MT5 is a 64-bit, multi-threaded system with a more distributed server design. In plain terms, it handles heavier loads and more simultaneous connections with less strain. MT4 can still perform well, but brokers with growing client bases tend to hit its limits sooner and end up patching around them with plugins.
Back Office and Integrations
Both platforms connect to CRMs, liquidity bridges and risk tools through manager and server APIs. The difference is that most vendors now prioritise MT5 development. New features, updates and support often land on MT5 first, and some providers have started treating MT4 integrations as legacy.
Licensing and Cost
This is simple. You can buy an MT5 licence. You generally can’t get a new MT4 one. White label pricing for both varies by provider, but MT5 gives you a clear path to owning your own server later, which MT4 no longer does.
So Which One Should a Broker Choose?
Choose MT4 if:
- Your target traders are heavily invested in MQL4 EAs and won’t move
- You’re running a forex-only operation with modest growth plans
- You can secure a stable white label from a reliable provider
Choose MT5 if:
- You’re starting fresh and want room to grow
- You plan to offer stocks, futures or broader multi-asset products
- You want direct licence ownership down the line
- You operate in markets where netting is required
Plenty of brokers run both, offering MT4 to legacy traders while pushing new sign-ups to MT5. It adds cost, but it keeps older clients happy during the transition.
Final Thoughts
The MT4 vs MT5 debate used to be about trader preference. Now it’s mostly about where the industry is heading. MT4 isn’t disappearing tomorrow, and it still has a loyal base. But for a broker planning the next five years, MT5 is the safer foundation in most cases.
At ForexTradeTech, the brokers we see making the smoothest decisions are the ones who start with their client profile and product plans, then pick the platform. Going the other way round usually ends in a costly migration later.
Frequently Asked Questions
1. Can a new broker still get an MT4 licence?
Not directly in most cases. MetaQuotes stopped selling new MT4 server licences some years ago. New brokers usually access MT4 through a white label from a company that already holds a licence.
2. Will my clients’ MT4 Expert Advisors work on MT5?
No. MT4 uses MQL4 and MT5 uses MQL5, and the code isn’t interchangeable. EAs need to be rewritten or replaced with MT5 versions, many of which already exist in the MQL5 marketplace.
3. Is MT5 better for forex-only brokers?
It can be. Even without other asset classes, MT5 offers faster performance, more order types, more timeframes and a stronger strategy tester. The main reason to stick with MT4 is client attachment to existing tools.
4. Can a broker offer both MT4 and MT5 at the same time?
Yes. Many brokers do, usually connecting both platforms to the same CRM and liquidity setup. It increases running costs, so it makes most sense when you have an existing MT4 client base to keep.
5. How difficult is it to migrate from MT4 to MT5?
The technical migration is manageable with the right provider, covering account transfers, group settings and integrations. The harder part is moving clients, especially those who rely on MT4 EAs. A phased approach with both platforms running side by side tends to work best.
