http://daytrading.about.com/od/brokerageprofiles/fr/TradeStation.htmTradeStation provides trading software called TradeStation. TradeStation is full featured trading software, but will only run on recent Windows systems. TradeStation provides an API (application programming interface), and supports both custom indicators, and other programs (such as charting or order entry software). The API uses a proprietary programming language called Easy Language, but Easy Language supports external DLLs (Dynamic Link Libraries), so it can be interfaced with standard programming languages, such as C/C++.
这个在国外知名度应该蛮高的~
