vix_utils provides command line tools and a a Python API for preparing data for analysing the VIX Futures and Cash Term structures. Term Structure data can be exported to excel (.xslx), csv, and pickle formats.
License: MIT License
Non-obvious errors are thrown when user calls the synchronous API functions in an event loop.
For example, using in Jupyter
will result in errors that are net helpful in working around the issue.
I tried using a Jupyter notebook import values from vix_utils to print a term structure though it won't work due to asyncio. Even adding %autowait asyncio did not help.
This is a nice to have IMO. I was able to work around it by running python from command line, exporting values to a .CSV, then importing those into the Jupyter notebook afterwards.
Hello,
it seems that destination URLs for cash VIX assets are no longer avaliable:

The data for #days remaining in each contract for a 30 day continuous maturity aren't quite right and they don't match the SVIX documentation.
"What is the command line equivalent of -r so I can use/run src\examples\sample_plots.py?
Goal is to display the cash term structure with 1st, 2nd, etc month futures values (VX1, VX2, ...) using data pulled by vix_util.
3-24 Add: I was able to successfully run examples\sample_plots.py. That said its comments state you need to first run vixutil -r to download data which wasn't true with this version. That's a sample/comment bug. Updating docs to reflect there is now no -r command line option would be a plus :)"
From a comment in #15
Instead of just the examples and readme.md, some documentation on how to use would be expected.
use github actions to build releases with flit and publish to pypi.
working on it.
If you are interested in this project, maybe use the command line utility to generate the weighted 30 day tenor and look for anomalies.
Same for the other outputs though I think these are less likely to have errors, except perhaps the weights from vixutil -w
These should be minor, but pandas_market_calendars may indicate CBOE was open when it wasn't on the odd holiday, including June 19, 2023.
I got sample_plot_term_structure.py working over weekend and it seems to work with yesterday's date (e.g. 2023-03-24 on Sat 3-25). However it doesn't work with today's date well after 16:00 Central/CBOE time (e.g. 4:50PM Pacific), when Yahoo finance has CBOE values for for 1st and 2nd month forward contracts after today's close.
You should be able to repro this by editing src/examples/sample_plot_term_structure.py - changing the day_of_interest value to today's date (after market close). E.g.
#plot the term structure for Mon Mar 27, 2023
day_of_interest = '2023-03-27'
df_day_of_interest =wide_with_continuous_futures.loc[[day_of_interest]]
This is the output from running the sample with above change. It works if I set day_of_interest to '2023-03-24' and Yahoo finance has CBOE values for market close for 1st and 2nd month forward contracts.

Coming soon, SHORTVOL and LONGVOL will be added. Could be useful for those backtesting prior to the launch of SVIX and UVIX.
It is already in this branch. https://github.com/dougransom/vix_utils/tree/dev_202307.
I hope to release it in a month to pypi.

Best regards
see the graph produced by vix_sample_plots.exe/sample_plots.py.
Maybe the date or interval is off by one.
This is for 2021-02-26.
It take awhile to load the data into a dataframe for the futures history, even though most of it is cached.
Any futures which are not expired, are read every time a program is run (at least the results are cached for the remainder of the program).
some logic to avoid rebuilding the dataframe, as long as all futures downloaded are current to the end of the most recent close of trading, would speed this up immensely.
I think the easiest way to to look at the last trade date in the cached data stored in skinny.pkl.
Only if the most recent close of trading is more recent that the last recorded trade date (say be 30 minutes since there will be delay before CBOE publishes the current day), then rebuild the dataframe in async_load_vix_term_structure.
Doug awesome work here. what dataset is CBOE VX data from ?
