MT4 vs MT5: choosing in 2026
MT4 still wins on certain client demographics; MT5 wins on instrument breadth and modern API. We map four operating-model questions onto the choice — pick the one where your gotchas don't bite you.

MT4 is not dead. MT5 is not universally better. The right answer depends on four operating-model questions — answer them honestly and the platform falls out.
1. Who are your clients?
If the bulk of your client base is older retail FX traders coming from MT4 brokers, the friction of moving them off MT4 is real and persistent. Start there.
2. How many instrument classes will you offer?
Index CFDs, futures, equities, crypto — MT5's instrument model handles these natively. MT4 needs synthetic symbols and that complexity adds up.
3. Do you need a modern API surface?
If your operations rely on a custom CRM, internal tooling, or third-party reporting that hits the platform daily, MT5's manager API is the cleaner option.
4. Which LPs do you actually have?
LP coverage on MT4 bridges is still deeper for retail FX. On MT5 it is excellent for major venues and improving fast for niche flow.
What we recommend
Most new brokers should default to MT5. The ecosystem and instrument model justify the migration friction. The exception is a known retail-FX-only audience that already lives in MT4 — leave them where they are and serve them well.
