As the name of the book indicates, it is just an brief introduction to ichimoku charts. The author spends approximately the first one third part of the book to demonstrate basic components of the ichimoku and the rest about other relevant principles. From my perspective, I have not learnt much about ichimoku charts. Warnings to people who intend to read this book, you should have basic understanding about Elliot waves and options trading to find this book more useful than I am.
