Thanks for the link, that was useful. I found there about koyfin.com which is for free and gives the summary info that I was after. Really spot on. Source: about 4 years ago
My stock dashboard (koyfin.com) says 15.33% short interest. Which is correct? Also I think that number was around 25% recently so I guess that's come down? Source: over 4 years ago
Personally: For individual stocks: Koyfin.com (good for visualizing US ETFs as well but you won't have access to those anyway). Source: almost 5 years ago
