A reader has asked why I think How Charts Can Help You in the Stock Market by William L. Jiler is better than the three of the most popular books on technical analysis:
Technical Analysis of Stock Trends by Edwards and Magee
Technical Analysis of the Financial Markets by John J Murphy
Encyclopedia of Chart Patterns by Thomas N. Bulkowski
I have read all three and can say with great amount of conviction that Jiller book is hundred times better than these three tomes. Now that is my opinion you can test it for yourself. The book is less than the cost of commission you will pay on a trade. It has 200 pages and you can finish it in few hours. It is more geared towards trading. Popularity of a book does not mean the ideas in it will be profitable.
