Volman, Brooks, Ross, and every other "price action" guru trade bars (or candles), not price, and bars are, like indicators, derivatives of price. If you want to trade price, then trade price, not bars or candles. If you'd rather trade bars or candles or even indicators, then you will more likely than not find yourself tumbling down the rabbit hole.
The usual fallacies regarding cause/effect and correlation apply to "favorite books", i.e., I read/studied this book and my results improved and/or I became a successful trader, etc. However, the "success" may have had far less to do with the book than with the period spent studying the market -- and price action -- as a result of reading or having read the book. IOW, reading the book but not going through the stage of studying price action itself is not likely to make much difference with regard to one's results (which is often the chief cause of complaints about having read such and such and tried it for a few days and had no success with it at all). And given the torture than some of these books represent, the beginner is far more likely to achieve a successful result -- and a more enjoyable one -- if he studies the object of his quest, i.e., price movement, than if he spends/wastes a lot of time slogging through book after book. You're going to have to study the actual price movement anyway, eventually, so the sooner you get to it, the better. Yes, a book or books can guide you and show you what to look for, but this needn't take hundreds of pages and truckloads of gobbledygook. The most important elements of what to look for can be covered, like Tom says, in a pamphlet.
If you have no idea what the difference is between trading price and trading bars, I suggest you read
this thread. It's short, sweet, clear, and painless. And you'll understand far more about what it means to "trade price" than most beginners do. And you won't be spending hundreds of unnecessary dollars on books. As for how to study price, I suggest you consult
the pdf attached to the bottom of this post. It too is short and painless.
