IB Communique Interactive Brokers - June 24, 2005 Launch of Re-designed Interactive AnalyticsSM We are pleased to announce the launch of our re-designed suite of mathematical risk assessment tools, Interactive Analytics (IA). These tools are provided to all IB customers for free as part of the Trader Workstation platform, while third-party providers charge a substantial fee for similar items. IA is composed of three modules: Portfolio Analytics which lets you assess the risk of your entire portfolio across asset classes and look at the risk of 揥hat-if?scenarios; Option Modeler that automatically calculates model option prices based on live market data including the implied volatility smile; and Option Analytics which lets you focus on the risk and valuation of specific option contracts. With our next release of IA, we will add Value at Risk (VAR) measures.
