Thank you for the 2 examples, that helped the investigation of the issue. It's a bug in the code due to Good Friday, you are right.
I just fixed it, but there are some delays for the import of the data from yesterday.
I've added a new column in the "Straddle Table' page (bad name) : historical earnings volatility which calculates the historical volatility of the 8 previous stock movement around the earning. It's still a work in progress.
I've been doing some changes to display the strikes in the RV chart when you hover on a point, but it will only appear when i reset the RV charts cache. I will probably do that during Good Friday long weekend to have the time to rebuild the whole cache.
