“I recently finished reading your book, DIY Portfolio Management. I consider myself a beginner in trading system design and testing, and found your book to be very helpful in developing new trading strategies.

In regards to the specific content of your book, I found the following material most helpful to me: regression to the mean (Chapter2), your use of TRIPs% as a comparative parameter in back-testing ( Chapter 4 risk management (Chapter 10), and your expo on cycles (Chapter 11).

My main platform for trading system development is Metastock with TradeSim for back-testing and Monte Carlo simulation. However, since reading DIY Portfolio Management I've been developing my own simulation tools in VB and in Excel.

Thanks for sharing your practical Trend Regression Portfolio Stratagey"
