MetaTrader 5, most commonly known as MT5, is an advanced multi-asset online trading platform launched in June 2010 by MetaQuotes Software Corp. It is designed to support trading in Forex, CFDs on stocks, commodities, indices, and in some cases, cryptocurrencies.
MT5 is available as a desktop application, mobile app, and WebTrader that can run in any browser.
Its popularity comes from a combination of ease of use, advanced technical tools, customizability, and support for automated and algorithmic trading via Expert Advisors (EAs). The platform also includes backtesting capabilities, making it well-suited for both beginner and advanced traders.
