MetaTrader 5 (MT5) and MetaTrader 4 (MT4) are popular trading platforms, but they differ in several aspects. MT5 offers more advanced features than MT4, including a wider range of order types, additional timeframes, and improved technical analysis tools. MT5 supports more asset classes, including stocks and futures, whereas MT4 primarily focuses on forex trading. MT5 also has a built-in economic calendar and depth of market functionality, which are not available in MT4. Furthermore, MT5 has a more modern and intuitive user interface, providing a better overall trading experience.
