With the publication of this new content we give continuity to the first book "The Wyckoff Methodology in Depth", where all the analytical tools that this methodology addresses are presented in a clear way, as well as the more theoretical aspect in the study of the behavior of financial markets. In this book we will go a step further and address more complex concepts; we will review the doubts most commonly raised by students of the methodology and incorporate new tools based on the information provided by the volume data that will be very useful, such as the Volume Profile and Order Flow. I strongly recommend that before starting the study of this book you have previously internalized all the concepts covered in the first one, since everything seen is taken as understood and, if not, it could cause some confusion or lack of understanding.
