MT4’s automation features are powered by its built-in programming language, MetaQuotes Language 4 (MQL4). This powerful and intuitive language allows users to create custom indicators and expert advisors (EAs) that can automate trading processes. With access to MQL4, traders can also backtest their strategies using historical data to optimize performance and reduce risks.
