Between those strikes Zomma and Vomma are negative, which usually is not something you want.Quote from babutime:
I think you may have missed a few words there but did you mean those are strikes which, ceteris paribus, DGammaDVol and DVegaDVol are good to you out of the rest of the strikes? So basically strikes which dont have Vomma and Zomma priced into them as much compared to the rest of the strikes?
Out of those strikes you have Zomma and Vomma positive, which is good.
By the way, Zomma boundaries are far larger than Vomma's, but at long expiries it's often not possibile to find affordable bid-ask spread at those strikes because they become larger and larger with increasing days to maturity.

I work in a inv. bank desk, so I use Bloomberg to API them in Excel and make everything there.Quote from babutime:
How does one go about obtaining data for the term structure? IB surely doesnt have that feature (even its skew-analytics suck compared to ThinkOrSwim). Before I knew about TOS, I had to manually scrap data from sites like yahoo finance and such. Took 10-20 seconds to generate a skew curve that was 15 minutes delayed (I know I have zero patience).
Or maybe you just use some brokerage software that I simply cannot afford at the moment? There's a bloomberg terminal at school which has it all. But then I realized that it's almost an hour delayed....
