This website is the home for the book,
Modeling Trading System Performance,
by Dr. Howard Bandy

Deciding the size of the position for the next trade is a two question process:
1. Is the system working or is it broken?
2. What is the position size that maximizes the probability of meeting my account growth goal while minimizing the probability of suffering a serious loss?

Modeling Trading System Performance is a sequel to my earlier book, Quantitative Trading Systems. The focus of the new book is on the practicalities of trading as a business. Key topics include:

Most of the material in Modeling Trading System Performance is new, both in terms of books published by Blue Owl Press and in terms of other published materials.
There is less than 5%  overlap between Modeling Trading System Performance and Quantitative Trading Systems.

Several trading systems are analyzed in detail. Everything is completely explained, including use of free or low cost tools that will enable you to perform similar analysis of your own trading systems. Other than Microsoft Excel, the book is platform independent. It is equally applicable to people who develop using TradeStation, MetaStock, AmiBroker, Wealth-Lab, or any other trading system development platform.

People who have reviewed early drafts are enthusiastic.
One person said he thought this was the most important technical analysis book he had ever read.

Several common wisdom, traditional method, and sacred cow ideas and recommendations are examined in detail, with results showing that many of them are poor advice. All of the tools used are fully explained so you can repeat the tests using your own systems and data.

Using AmiBroker

I am regularly asked why the examples in the book use AmiBroker.

I struggled with choice of platform to use to illustrate the techniques, and chose AmiBroker because:

  1. It is capable of performing everything I wanted to do ( I do not know of another reasonably priced platform that can ).
  2. It is inexpensive to buy ( free to try, and the trial version can do everything I describe ).
  3. It has a very clear and concise language that should be easily understood by anyone who is reasonably comfortable programming for a different platform.

No matter which platform I chose, some people would be disappointed.

You can get an idea of AmiBroker's language from the sample chapters of my books ( available at their websites -- links at the bottom of this page ), from the example programs at my blog site, and from the monthly articles in Technical Analysis of Stocks and Commodities magazine.

So the answer depends -- on the capabilities of the platform being used and the capabilities of the programmer doing the translation.

For those people who are not already familiar with AmiBroker and want to test the techniques I describe:

  1. Download the free trial version of AmiBroker from the AmiBroker website.
    http://www.amibroker.com/
  2. Download and read the free "Introduction to AmiBroker" from that book's website. It has complete instructions for installation, setting up databases, and using the platform in both charting mode and analysis mode.
    http://www.introductiontoamibroker.com/
  3. Paste in some of the AmiBroker code I provide and try it out.
    http://www.blueowlpress.com/WordPress/trading-systems/mean-reversion-based-on-rsi/

The code for both the Mean Reversion book and the Quantitative Trading Systems book is available for download, copy, and paste.

In my opinion, the arguments I make for quantitative trading systems in general, and for mean reversion systems in particular, are compelling. The techniques fully disclosed and worth studying, and the results are reproducible, worth examining, and worth comparing with alternative trading systems on alternative platforms.

If you don't like it, don't use it.

But I do recommend making your comparison using sound modeling and forecasting techniques, realistic estimates of future performance of each system, and on a risk-normalized basis -- the procedures are fully explained in "Modeling Trading System Performance."


About Kindle

Mean Reversion Trading Systems will first be published as a printed and bound book, in the same format as the three previous books. It is 240 pages long and has many program listings, screen capture images, and charts and graphs. The resolution when printed is the same quality as the previous books.

I have two Kindle readers. A Kindle Ink with a 6 inch screen, and a Kindle Fire HD with a 8.9 inch screen. The book displays very well on the Kindle Fire, but not so well on the Kindle Ink. After the initial orders for the printed book have been filled, and I return from the world-wide promotional tour (that is happening, right?), we will begin translation to Kindle format. None of the programs we have tried so far to convert from publisher's files into Kindle format work well. Consequently, the translation will be manual, page by page, image by image.

There is often discussion about the cost of Kindle books, with customers expecting everything to be $1.99, justifying that because there is no publishing cost. My first response is that this book is valuable because of its intellectual content, not as recycled paper. My second is that there is a publishing cost. It begins with the cost of writing, editing, and formatting. Even if we assume that has already been paid for by the printed version, there is the cost of translation to ebook format. Additionally, Amazon charges the publisher a transmission fee of $0.15 per megabyte of the file that is downloaded. The publisher / author receives the net of 35% of the price of the book, less the transmission fee. Do not expect the ebook versions to be less expensive than the printed versions.

At about the same time this book will be made available in Kindle format, we will list this book, and all of our other books, on Amazon and let them handle the order and fulfillment process. I cannot yet forecast the date accurately.


Kindle will be the first ebook format. If there is sufficient demand, we will consider translating into other ebook formats after the Kindle program is running smoothly.
