Python Eikon Integration - Function "FxCalcPeriod()"

Hi, Could you send more information about instrument Pricing Analytics (IPA) for Eikon user?

What technology will you be able to connect to use and download data? when do you plan to implement? will it be possible to download data via websocket?

@danielbarroso

This is how to do it (I used the argument of FxCalcPeriod for my needs, but one can change that). Note that you have to be running this on Python 32 and follow the steps in

https://developers.refinitiv.com/en/article-catalog/article/using-adfinx-analytics-in-python

to install what you need.
