This is a strange book, despite the title, it's not really about trading or investments in a substantive manner. Instead, it's more like "a day in the life of Jesse Livermore", the infamous early 20th century trader. I first learned about this individuals from the book "The Zurich Axioms", who portrayed him as charlatan, who claimed to use clairvoyance for his stock selection.
Despite his outsized profits, he never was fully taken seriously by the Wall Street crowd of the time because of this reputation. He evidently published a small book on "serious" analysis / strategies for trading late in his life, but according ot the "Zurich Axiom", those advice often led to catastrophe for their users (thought what they were were never specified).
This book is not really about Livermore's ideas (serious or otherwise), and mostly like a short tract on how he organizes his life around his work, and how this organization allows him to increase his chance of success. The best advice given is to sleep early and wake early, since the extreme early mornings allow one to meditate on deep notions. Totally agree, though a bit challenging to implement if you want to have a life outside of trading. The other advice have much to do with the way he laid out his office to best "read the tape" (the book was literally written when tapes were how one got trading information), and how he setup his office to exploit the information he was receiving. I suppose this would be akin to setting up your trade desk on a computer, or maybe setting up/building an analytic dashboard via computer.
Being on an hour and a half long, and the nature of the content, it's easily skippable. Not recommended.
