MetaTrader 4 is based on a prior generation (version) of software, whereas MetaTrader 5 is the latest version. In addition to CFDs and forex trading, MT5 can support stock trading and futures trading, making it more of a multi-asset platform. MT5 also includes advanced functions like utilizing cloud storage to run strategies and to conduct backtesting. With MT4, backtesting must be done locally or through a virtual private server (VPS). While it looks and feels similar to MT4, MT5 is a faster, more modern trading platform. Check out our MetaTrader 5 guide to learn about the platform's advanced features and to get a behind-the-scenes look at mobile, web, and desktop versions of the platform. Though MT4 is still more widely used, the number of MT5 servers recently surpassed the number of MT4 servers globally (it took only a decade). This is mainly because more MT4-only brokers continue to launch MT5, offering the full MetaTrader suite, in addition to increasing the range of trading products available on MT5.
