> SSRN provides 1,453,207 preprints and research papers from 1,847,303 researchers in over 65 disciplines.
It's basically like Arxiv, but focused on different fields. The articles may be preprints of peer reviewed articles published in leading journals, or they may be mad ravings uploaded by a crank, or anything in between. Also see wikipedia's article on SSRN[1].
From SSRN's page on Algorithmic Finance[2], the supposed journal (reachable by following the link under the article title):
> The journal archives all papers on SSRN
Note that the journal managing editor and contact is the author of the paper, the contact info appears to be his personal contact info, and all links on the page are dead.
