The MT4 vs MT5 debate has raged for over a decade. While MT4 remains popular with traders, the landscape for new brokerages has shifted significantly. Here's our practical take for brokers launching in 2026.
The Current Landscape
MetaQuotes stopped selling new MT4 licenses years ago. If you're launching a new brokerage today, MT5 is effectively your only choice from MetaQuotes. Some white-label providers still offer MT4, but new standalone licenses are no longer available.
This isn't necessarily a bad thing. MT5 has matured significantly and now offers everything most brokers need.
Where MT5 Excels
Multi-Asset Support
MT5 was designed from the ground up for multi-asset trading. If you plan to offer stocks, futures, or other exchange-traded instruments alongside forex and CFDs, MT5 handles this natively while MT4 requires workarounds.
Performance
MT5's 64-bit architecture handles more data, more indicators, and more concurrent connections than MT4's 32-bit design. For brokers scaling to thousands of clients, this matters.
Modern Development
MQL5 is a more powerful programming language than MQL4. If you plan to develop custom indicators, EAs, or integrations, MQL5 offers object-oriented programming and better debugging tools.
Depth of Market
MT5 includes native Depth of Market (DOM) display, useful if you're offering ECN-style execution or want to display level 2 pricing.
Where MT4 Still Has Advantages
Trader Familiarity
Many experienced traders know MT4 inside out. The interface is burned into their muscle memory. MT5's different layout can cause friction, especially for traders switching from another MT4 broker.
EA Compatibility
There's a massive library of MT4 EAs that don't work on MT5. If your target market relies heavily on specific MT4 trading robots, this could be a significant barrier.
Hedging Mode
MT5's default netting mode confused many forex traders accustomed to MT4's hedging. While MT5 now supports hedging mode, it wasn't always the case, and some traders remain wary.
Our Recommendation
For new brokers in 2026, we recommend MT5 for most scenarios:
- If you're starting fresh: Go with MT5. The ecosystem is mature, risk management tools are robust, and you're future-proofing your technology stack.
- If you need MT4: Consider a white-label arrangement or acquisition of an existing license. Be prepared for higher costs and limited vendor support going forward.
- If you want both: Some brokers run both platforms to capture different trader segments. This increases operational complexity but maximizes market reach.
Technology Considerations
Whichever platform you choose, make sure your technology partners support it fully. This includes:
- Risk management systems (like Finnovic RMS for MT5)
- Liquidity bridges
- CRM integrations
- Copy trading solutions
- 24/7 technical support
A platform is only as good as the ecosystem around it. Make sure you have partners who can support your chosen platform around the clock.
