This is a pretty good book with pretty good examples of Morales/Kacher's pocket pivot buy point, buyable gap-up purchases, and significant emphasis on using stock price action and volume of shares traded to guide all investment decisions.
The authors also make an excellent point about the difference between buying as a consumer versus buying as a trader or investor. Stated simply, don't buy a stock with the intent of seeking the lowest price. That strategy might work for buying sweaters and other goods/services but it's not the O'Neil Disciples trading strategy.
There is significant emphasis on risk management, selling stocks early if their stock price action doesn't do what you wanted, and lots of chart examples and exercises dealing with pivot points and buyable gap-ups.
I read this book on Nook. I don't know for sure but the charts may be a little clearer in a printed edition. I still like ebooks more than a paper book so it wasn't that big of a deal to me.
