Volatility Levels
The VolLevels algo is a critical analysis tool for options traders using Exegy’s Metro platform. The VolLevels algo condenses important volatility trading information into nine separate grids: “Changes By Delta”, “Changes By Strike”, “Changes By Sigma”, “Current Vols”, “Relative Value By Delta”, “Relative Value By Sigma”, “Skew & Kurtosis”, “Butterflies”, and “Trade Performance”. The three “Changes By” grids provide insight into net changes in IV, as well as the high/low in net changes, from floating (delta), sticky (strike), and standardized moneyness (sigma) perspectives.
The two “Relative Value” grids allow comparisons across the term structure by displaying the IVs as ratios. The “Skew & Kurtosis” grid displays six different metrics quantifying the volatility surface. The “Butterflies” grid displays IV info on ten predefined butterflies across the term structure. The “Trade Performance” grid displays live metrics on individual intraday trades, including live IV, live P/L $ values, and live closing edge. The “Trade Performance” grid can be customized with nine optional settings.
Range tracking (intraday high/low) is provided for many metrics in the grids. The algo can monitor both monthly and weekly options in any number of products. The information provided is critical to avoiding poor trades that might otherwise appear superficially attractive, and consistently identifying profitable trades with quantitative confirmation from multiple perspectives. The VolLevels algo is compatible with any vol curve type(s) and can monitor vol curves updated either manually or automatically. It is the perfect complimentary tool to use in conjunction with our revolutionary realtime curve fitting tool: the Dynamic Skew algo. With a constant IV data stream generated by the Dynamic Skew algo, the VolLevels algo can realize maximum potential with the highest resolution of IV. A special bundled price discount is available to users who license both the VolLevels algo and the Dynamic Skew algo: the VolLevels algo can be licensed at a 50% reduced price ($300/month) in this scenario.
