The Platform Question Every New Trader Faces
MetaTrader 4 (MT4) and MetaTrader 5 (MT5) are the most widely used retail forex trading platforms in the world. Together they account for the majority of retail forex trading globally. When choosing between them, traders face a surprisingly nuanced decision that depends on their trading style, instrument preferences, and technical requirements.
MetaTrader 4: The Industry Standard
MT4 was released in 2005 and quickly became the industry standard for retail forex trading. Its dominance is remarkable — nearly twenty years after release, it remains the most widely supported platform among forex brokers and the most requested platform by retail traders.
MT4 strengths: massive ecosystem of indicators, expert advisors (EAs), and scripts available through the MQL4 marketplace, extremely stable and lightweight performance, universal broker support, and a familiar interface that thousands of YouTube tutorials, books, and courses use as their default environment. For pure forex (spot currency pairs) trading with automated strategies, MT4 remains the benchmark.
MetaTrader 5: The Updated Architecture
MT5 was released in 2010 as MetaQuotes’ next-generation platform. It offers a different architecture with multi-asset capability (stocks, futures, options, and crypto alongside forex), a more powerful strategy tester, additional order types (including buy stop limit, sell stop limit), an economic calendar integrated into the platform, and the MQL5 language which is more powerful than MQL4.
MT5 weaknesses: the MQL4 and MQL5 languages are not directly compatible, meaning the vast library of MT4 expert advisors does not transfer to MT5. Hedging (holding simultaneous long and short positions on the same pair) is handled differently in MT5, which affects some strategies. MT5 broker availability has improved significantly but still trails MT4.
The Verdict: Which to Choose
Pure forex traders using existing MT4 strategies or EAs: MT4. Traders wanting multi-asset access (stocks, futures), advanced backtesting, or starting fresh without an EA library dependency: MT5. Both platforms are excellent. The choice is primarily determined by your existing strategy infrastructure and the specific instruments you trade.
