Can current version of eikon python retrieve live data?
The first version of the Eikon Data APIs for Python will be released in Q2. As @Zhenya Kovalyov explained, this version will not include live data. Another version including real-time streaming data will follow later this year. I do not have any precise date to communicate yet, but I can tell you that we are working on the feature.
You can only take snapshots of the live data, streaming will be available in the next release of the API.
