Choosing between MT4 and MT5 expert advisors is one of the most common questions traders face when automating their strategy. While both platforms support automated trading, they behave differently under real market conditions. The right choice depends less on hype and more on how execution, risk control, and flexibility actually work.
MT4 was designed primarily for forex trading and remains popular due to its simplicity. MT5, on the other hand, is a multi-asset platform built with more advanced order handling, better data structures, and improved execution logic.
- MT4 focuses on simplicity and legacy EA compatibility
- MT5 supports more asset classes and modern execution models
