I need historical NAV data for all listed US closed-end-funds.
I searched a little, but gave up.
I found several sources for end-of-day only (previous day NAV), but nowhere to download it in some txt format so it's not easy to make good use of. For example Morningstar and Bloomberg websites give good updates on the NAV but you have to manually scan them one by one.
Is there a site to download end-of-day in a file?
Or even better, historical?
