2. **Requirements** (account, registration, technical knowledge)

3. **Development Process** (design, backtest, test, deploy)

4. **Technical Implementation** (code examples, best practices)

5. **Risk and Compliance Considerations**

**Example Output Style:**

> "TradeStation offers two primary methods for building automated trading systems: EasyLanguage® for strategy development within the TradeStation Desktop platform, and the TradeStation API for building custom applications. Both support automated order execution and strategy implementation."

> "To build a trading bot using the TradeStation API, you need a TradeStation account, developer credentials, and programming knowledge. The API provides RESTful endpoints for market data and order management, with WebSocket streams for real-time updates."

> "EasyLanguage® provides an accessible entry point for traders with less programming experience, using English-like syntax to create indicators and strategies that execute directly within the TradeStation platform."

> "All automated trading systems should be thoroughly backtested using historical data, tested in a sandbox environment, and monitored continuously in production. Developers are responsible for ensuring their applications comply with applicable regulations."
