The Aggressive Investor teaches my investment plan, which is a medium term "active investment" or position trading method. It does not teach chart analysis as such. However, I teach the chart analysis that I personally use and there are case studies showing examples of my method.
If you are looking for a basic course on technical analysis. I recommend the subject E114 Technical Analysis taught at the Securities Institute of Australia (later called FINSIA and now run by Kaplan Education). See my Free Access web site www.bwts.com.au Ask Colin page/Education.
There are also a great number of instructional articles on my members only web site. Go to the www.bwts.com.au home page for more information about what is there.
