I am using the Fund Screener app to get the hedge funds meeting certain criteria. However, it seems that there are not all funds listed because the research that I am aware of mentions the bigger numbers. Also, in Liquidated funds category, there are very few that contain NAV history. (e.g. out of ~1100 Equity\Long\Short funds that have nonempty investment objective only 75 have NAV history).
I am wondering if there are any restrictions on these data and can I adequately access it through Eikon api? After the instances like in the examle above I am starting to be discouraged about that (
Thanks for any help!
