MetaTrader 4 and MetaTrader 5 are the two dominant trading platforms in retail forex, and choosing between them is one of the first practical decisions new traders face. Despite being developed by the same company (MetaQuotes), these platforms differ significantly in features, capabilities, and suitability for different trading styles. In 2026, both platforms remain actively supported, though the industry is gradually shifting toward MT5.
Platform Overview
MetaTrader 4 (MT4) was released in 2005 and has been the industry standard for nearly two decades. Its simplicity, reliability, and massive library of custom indicators and Expert Advisors have earned it a devoted following. MetaTrader 5 (MT5) launched in 2010 with expanded capabilities including more timeframes, built-in economic calendar, depth of market, and multi-asset support. Despite being newer, MT5 initially struggled with adoption but has gained significant ground in recent years. For volatility-based entries, see our Bollinger Bands strategy guide.
Feature Comparison
MT5 offers 21 timeframes versus MT4's 9. MT5 includes a built-in economic calendar; MT4 does not. MT5 supports 38 built-in indicators versus 30 on MT4. MT5 allows unlimited charts; MT4 limits to 99. MT5 includes depth of market (DOM) functionality. MT5 supports stocks, futures, and options in addition to forex and CFDs. MT5's strategy tester is multi-threaded, dramatically faster than MT4's single-threaded tester.
Programming Languages: MQL4 vs MQL5
MT4 uses MQL4, a simpler programming language that most forex EA developers know well. MT5 uses MQL5, an object-oriented language that is more powerful but has a steeper learning curve. The MQL4 and MQL5 libraries are not compatible, meaning Expert Advisors written for MT4 must be rewritten for MT5. This compatibility issue remains the primary barrier to MT5 adoption for traders with extensive MT4 EA collections.
Order Execution Differences
MT4 supports four order execution types: instant, market, exchange, and request. MT5 supports these plus additional pending order types: Buy Stop Limit and Sell Stop Limit. MT5 also offers netting and hedging position management, while MT4 is hedging-only. For forex traders who use hedging strategies, both platforms support this. MT5's additional order types provide more precision for advanced order management.
Speed and Performance
MT5 is 64-bit software, allowing it to use more system memory and process data faster than the 32-bit MT4. Backtesting is significantly faster on MT5 thanks to multi-threaded strategy testing that utilizes multiple CPU cores. Live execution speeds are comparable between platforms, as execution speed is primarily determined by broker infrastructure rather than platform software.
Which Should You Choose in 2026
Choose MT4 if you have existing Expert Advisors written in MQL4, rely on specific MT4-only indicators, or prefer the simplest possible interface. Choose MT5 if you want the most advanced features, plan to trade multiple asset classes, need faster backtesting, or are starting fresh without existing MT4 tools. For new traders in 2026, MT5 is the recommended choice as it represents the future of the MetaTrader ecosystem.
Frequently Asked Questions
For new traders, MT5 is recommended as it offers more timeframes, faster backtesting, built-in economic calendar, and represents the future of MetaTrader. Only choose MT4 if you have existing Expert Advisors or indicators that are not available for MT5.
No, MT4 and MT5 use different programming languages (MQL4 and MQL5). Expert Advisors must be rewritten to work on the other platform. This incompatibility is the main reason some traders remain on MT4.
MT5 is 64-bit software and uses multi-threaded backtesting, making it significantly faster for strategy testing. Live execution speeds depend more on broker infrastructure than platform software, so differences are negligible in real trading.
Most major brokers offer both MT4 and MT5. However, the industry trend is toward MT5, with some newer brokers offering only MT5. Brokers like Exness, XM, IC Markets, and Pepperstone support both platforms.
MT5 has a slightly steeper learning curve due to more features and options. However, the basic trading interface is very similar to MT4. Most traders familiar with MT4 can transition to MT5 within a few days of practice.
