TradeStation Analysis and Trading Platform
The TradeStation analysis and trading platform is a professional electronic trading platform for financial market traders. It provides extensive functionality for receiving real-time data, displaying charts, enter orders and manage outstanding orders and market positions.

Although it comes with a large number of pre-defined indicators, strategy components, and analysis tools, individuals can modify and customize existing indicators and strategies as well as display their own using TradeStation’s proprietary object- oriented EasyLanguage programming language. Traders can also access thousands of software trading products created by independent EasyLanguage developers through TradeStation Strategy Network, as well as access a collection of strategy trading ideas submitted by the TradeStation community in the EasyLanguage Library.

TradeStation supports the development, testing, optimizing, and automation of all aspects of trading. Trading strategies can be back-tested and refined against historical data[6] before being turned on and traded "live."

TradeStation can either be used as a research and testing tool or as a trading platform with TradeStation Securities acting as the broker.
