TWS Version 952 - Release Notes
Interactive Analytics: Implied Volatility Viewer Enhancements
The Implied Volatility Viewer, introduced in release 951, has been enhanced to include:
- The ability to edit the Interest Rate and Dividend Schedule, and to compose a basket of contracts. Make these selections from the Edit menu when the tool is in "Local PC" mode. To toggle modes use the right-click menu from within the chart. In "Local PC" mode, the model Implied Volatility is calculated based on the loaded option chains in TWS. In "Remote Server" mode, the model Implied Volatility is calculated based on the entire volatility surface for the selected underlying including all options in the related option chain that have a valid quote.
- Export Tool - When the tool is in "Remote Server" mode, the export command creates two .csv files: one of the observed data and one of the fitted model curve parameters
To open the Implied Volatility Viewer, from the New Window drop down select Options Analysis and then Interactive Analytics, then select Implied Volatility Viewer.

New Chart Indicator
A new comprehensive chart study, Correlation Coefficient, has been added to our charts. The Correlation Coefficient (PPMCC) measures the linear correlation or dependence between two variables, in this case between two securities, in an attempt to show how closely the securities are related to each other. The value is positive when both securities move in the same direction (either up or down) and negative when they move in opposite directions.
To use the Correlation Coefficient, from within a chart click Edit>Studies and in the Comprehensive Studies section select the indicator.
