Institutional ownership data/ratios

Hi
For my thesis, i am trying to gather monthly or quarterly institutional ownership data and ratios on US stock on a long time frame (preferably 1980-now). However, I have been working with the following python code, but are unable to as I do not have access to the product tr_13f which it is based on:
https://wrds-www.wharton.upenn.edu/pages/wrds-research/applications/institutional-ownership-research/institutional-ownership-concentration-and-breadth-ratios/
Does anyone have another method at hand? Preferably using python
Thanks

Hi!
Thanks.. I am now using the TR.CategoryOwnershipPct function in excel in a very manual fashion. Do you know any faster way to run it using code?

Hi @anders_pank ,
Have you tried using get_data function of LSEG Data Library. This page also include overview, quick start guide, and documentations related to it. The example code can be found at
For example,
import lseg.data as ld ld.open_session() ld.get_data(universe=['LSEG.L', 'VOD.L'],fields=['TR.CategoryOwnershipPct'])
