Product Review: PortfolioStream by Jayanthi Gopalakrishnan
A tremendous amount of work goes into creating a trading system. After creating one that works well
in one market, you’ll have to determine if the system is robust enough to apply to other markets. Testing that system over several securities can be a time-consuming task. To reduce the time necessary to test your system over different securities, RINA Systems, Inc., has developed PortfolioStream to automate the portfolio backtesting process. The backtesting can be performed for any trading system that works in TradeStation. PortfolioStream
uses TradeStation API (application programming interface), which means it must be used only with TradeStation 2000i.
