I am trying to download a file with websave.
While downloading the csv with my browser works fine, websave returns an empty csv.
test = websave("test.csv","http://stooq.com/q/d/l/?s=^aor&d1=20190303&d2=20190405&i=d")
Any ideas why this happens and how to fix this?
Like modifying the weboptions?

I have an idea. When I go to the url specified in the websave command (http://stooq.com/q/d/l/?s=^aor&d1=20190303&d2=20190405&i=d), I just get a blank webpage.
Try using the url that points directly to the csv file.

Thanks for the hint.
Unfortunately it did not work.
A full link would be:
test = websave('test.csv','https://stooq.com/q/d/l/?s=^aor&d1=20190401&d2=20190405&i=d/^aor_d.csv')
My IE actually showed a blank page with the shorter link, too. Firefox opened directly. With the full link IE now opens the file, just MATLAB does not.
I also tried enabling TLSv1.2. with a java.opts already, but it didn't help either.

I found one workaround.
web('http://stooq.com/q/d/l/?s=^aor&d1=20190303&d2=20190405&i=d', '-browser')
Then Firefox (my standard browser) opens and downloads the file correctly. The file appears in my firefox download folder. Then I can rename it can move it to where I want.
But as this is kinda inconvenient, maybe someone still has a more elegant solution?
