In general, books are a much better source of information than papers or blog posts when it comes to trading. I haven't read the one you posted, but a few I can recommend:
[0] is okay. I disagree with a lot in there, but it's pretty well written and one of the better books on the subject. [1] Is very old, but it's one of my favorites. It's very mathematical. The ideas still apply today. [2] Is a good introduction overview
