The thing about Bob Volman's books is you can't possibly read them in one sitting and not try to practice his set-ups as you flip the pages. That's the only way to retain information from this book.
This book is completely difficult to digest and if you're not practicing to spot the set-ups as you flip the pages, all of what's been said just goes in one ear and out the other.
That being said, this book is an excellent way to find out if scalping is for you. It's a comprehensive book geared to show the reader all there is about the profession and what it takes to be a consistent and profitable scalper. Plenty of set-ups will be presented over and over again to ingrain the techniques to the marrow.
If you want to learn the simplest way to scalp, this book is the best way to go. No fancy indicators, just one chart. Everything you need to learn is here: chart selection, price behavior, pattern recognition, favorable and unfavorable markets, set-ups, entries and exits, targets and stops, traps and tricks, psychological issues, and accounting matters.
The book serves as a journey. As you delve into the specifics of the many things a scalper must perfect in herself, by the time one is done with this book, she wouldn't recognize the older version of herself anymore.
