PowerLanguage is a proprietary programming language that was developed by MultiCharts, LLC. PowerLanguage is an advanced programming environment for creating technical analysis indicators and trading strategies forthe MultiCharts trading platform. It is a system of expressing financial instrument trading rules in a systematic and logical way that can be executed by a computer.
By supporting EasyLanguage developed by TradeStation, PowerLanguage maintains compatibility with a wide existing base of EasyLanguage indicators and strategies. As an alternative to writing indicators or strategies from scratch, existing studies can be modified, or new studies assembled piece-by-piece from built-in scripts. External DLL's can be referenced using PowerLanguage which greatly extends its functionality and permits the use of high-level programming languages, such as C++ or C#.
