MT4 vs MT5: Which Trading Platform Is Right for Your Brokerage?

The choice between MetaTrader 4 (MT4) and MetaTrader 5 (MT5) is one of the most consequential technology decisions a forex brokerage will make. While both platforms are developed by MetaQuotes and share a similar interface, they differ significantly in capabilities, architecture, and suitability for different brokerage models. This comprehensive comparison helps you make the right choice.

MT4: The Industry Veteran

Released in 2005, MT4 remains the most widely used forex trading platform globally. Its strengths include: a massive library of existing Expert Advisors (EAs) and custom indicators, a large and active developer community, simple and intuitive interface, proven reliability over two decades, and widespread client familiarity. MT4 supports forex and CFD trading with a hedging execution model.

MT5: The Modern Alternative

Released in 2010, MT5 is a more advanced platform designed for multi-asset trading. Key advantages include: support for stocks, futures, and options alongside forex, both hedging and netting execution models, faster backtesting with multi-threaded architecture, more timeframes (21 vs MT4's 9), more order types, built-in economic calendar, and improved programming language (MQL5). MetaQuotes has officially ended new MT4 license sales, pushing the industry toward MT5.

Key Differences for Brokers

• Asset classes: MT4 is forex-focused; MT5 supports multi-asset trading
• Execution models: MT4 supports hedging only; MT5 supports both hedging and netting
• Programming: MQL4 vs MQL5 — different languages, not directly compatible
• Server architecture: MT5 is more scalable and efficient
• Licensing: New MT4 licenses are no longer available from MetaQuotes

Which Should You Choose?

If you're launching a new brokerage, MT5 is the clear choice — it's the only option for new MetaQuotes licenses and offers superior capabilities. Existing MT4 brokers should plan a phased migration to MT5 while maintaining MT4 for existing clients. Some brokers offer both platforms simultaneously to accommodate different client preferences.
