TradeStation is considered the premiere trading software for individual traders and professional traders alike. I have been an end-user of the software since 1986 when I started using SystemWriter (no charting just calculations).

With version 9.0 TradeStation Securities Group introduced an extension to its EasyLanguage programming language called Object Oriented EasyLanguage. While its claim to fame had been the ease of use of EasyLanguage, and the English-like command structure, this new language (OOEL) is a fully extensible programming language. In structure OOEL is reminiscent of the programming language Pascal and has features of C++ that make it truly powerful.
