MT5 vs MT4 for Brokers: Which Trading Platform to Choose

For two decades, MetaTrader has been the default trading platform in retail forex. The question for a new or growing broker is no longer whether to use MetaTrader, but which version: the entrenched MT4, or its more capable successor MT5. The right answer in 2026 leans clearly one way, but the trade-offs are worth understanding.

MT4: the legacy standard

MT4 launched in 2005 and became the industry default. Traders know it, third-party tools support it, and its simplicity is a genuine strength. But it was designed for forex first and foremost, its multi-asset support is limited, and its development is effectively frozen — the vendor is steering the market toward MT5.

MT5: the modern successor

MT5 is a ground-up rebuild that addresses MT4's structural limits. It is faster, supports far more instruments natively, and is built for a multi-asset world. For brokers, the headline advantages are:

• Native support for forex, stocks, futures, and more from one platform
• More timeframes, order types, and built-in analytical tools
• An economic calendar and depth-of-market data built in
• Active development and the vendor's long-term support focus

Which should you choose?

If you are launching today, MT5 is the stronger default. It future-proofs your offering, supports the multi-asset products clients increasingly expect, and aligns with where the platform vendor is investing. The main reason to consider MT4 is a specific client base that already lives there or a dependency on an MT4-only tool — and even then, many brokers offer both.

Choosing a platform is a decade-long decision — optimize for where the market is going.
