Risk Navigator..... Ill Check that out. Do most trade with TWS at IB or do many use one of the myriad of other platforms?
I have no direct knowledge, but I assume the majority of IB traffic is institutional, that IB assumes we've all got IT over one shoulder, and Research over the other, and that we're all running an API with our Special Sauce poured all through it. (I'm completing my Special Sauce right now ["Ha!"], and expect to spend the next year putting it in Java for real-time connection. Still, you can do a lot with a periodic .csv off-load and a spreadsheet....
The risk navigator isn't up to where the TOS analysis tools are. Here's a little secret: Do you trading on IB TWS, do your analysis on an unfunded TOS account. You can import a trade log from IB to TOS with a little massaging and track your trades in real time there with *nice* risk graphs.
With some massaging, yes. I run an activity report, save it as a text file and run it through a custom Python script to get the TOS import/export format.
Have you looked through IB third party apps? Maybe something there. I haven't looked through them in ages though. https://www.interactivebrokers.com/Universal/servlet/MarketPlace.MarketPlaceServlet
Sadly there's not much in IB's 3rd party app collection for option trading, at least not a direct TOS replacement. OptionVue is probably the best for risk graphs, modeling and greeks but it's an expensive subscription.
Under the analyze tab in the Positions and Simulated Trades pane there's a menu button to the right. The Import Trades menu item does it. Just keep in mind you can't directly import trades from IB into TOS. The import is for TOS-formatted exported trades.
