I did check the related posts, like this one here.
However, given if one already has knowledge in finance, machine learning and statistics, and wants to know something more advanced on machine learning based trading rather than the introductory. What would you recommend?
I am looking for anything related: excellent books, research papers, posts, authors, as long as it is related to machine learning and trading in general, but the thing is, really looking for the sources with quality content rather than the ads sites.
