MetaTrader 4 (MT4) Review 2026
By MetaQuotes Software Corp. | Published May 2026
Platform Functionality & Usability
MetaTrader 4 (MT4) is the most iconic retail trading platform in forex history. Released in 2005, it established MQL4 as the standard for custom indicators and Expert Advisors. Even today, thousands of traders and EAs still run exclusively on MT4.
Our Verdict
MT4 remains a legendary workhorse for legacy EAs and simple forex execution, though new automated strategies should generally be built on MT5.

- •The largest historical database of custom EAs, indicators, and scripts
- •Extremely lightweight and fast on older or VPS hardware
- •Familiar, bulletproof interface tested by millions of traders over 20 years
- •Available across virtually every traditional forex broker globally
❌ Weaknesses
- •No native multi-asset support (strictly built for forex and simple CFDs)
- •Single-threaded 32-bit architecture limits backtesting speed compared to MT5
- •MetaQuotes has ceased major feature updates to encourage MT5 adoption
