MetaTrader 5 (www.metatrader5.com) is a popular multi-asset research and trading software platform that can be used standalone or connected to a compatible online broker. From performing fundamental and qualitative to technical and quantitative analysis, the platform feature deep in-depth functionality with numerous add-ons through its huge marketplace of third-party services.
To avoid confusion, MT5 is not necessarily an upgrade of MT4 since they address different end-users, markets, use different programming languages (MQL5 versus MQL4) and are not backwards compatible. MT5 is also better suited for U.S. markets as it accommodates U.S. regulations. Both platforms have massive followings worldwide with hundreds of brokers offering the platforms to customers.
