I can get the risk navigator to give me a tabular spreadsheet for an options position and what happens to it if volatility at a certain date goes up/down 15%/30%. Is there any way I can make it put it on the profit/loss graph that appears on the bottom of the risk navigator? For that matter, any way I can give it a volatility change that's not 15% or 30%? I haven't been able to find one and I feel like this has become a really regular complaint that I have with TWS -- there's a lot of stuff there, and a lot of really good stuff, but it's only 3/4 complete. If they just implemented the last 25% of the polish for the feature rather than stopping work on it (like here, letting me set my own volatility change, or even just putting it on the graph they draw!), TWS would be a truly stunning program.
