Rocket Science for Traders promises to revolutionize the art of trading by introducing modern digital signal processing to the playing field. The application of digital signal processing offers the advantage of viewing old problems from a new perspective. The new perspective gained by digital signal processing has led to the birth and development of some profoundly effective new trading tools. The advances in new trading tools, along with the continuing advancements in hardware capabilities, virtually ensure the continued application of digital signal processing in the future. The trader who masters the fundamental concepts of digital signal processing, therefore, will find great advantage when approaching the volatile market of the twenty-first century.

The Holy Grail of trading is knowing what the markets will do next. Technical analysis is the art of predicting the market based on tested systems. Some systems work well when markets are “trending,” and some work well when they are “cycling,” going neither up nor down, but sideways. In Rocket Science for Traders, noted technical analyst John Ehlers applies his engineering expertise to develop techniques that predict the future more accurately in these times that are otherwise so difficult to trade. Since cycles and trends exist in every time horizon, these methods are useful even in the strongest bull–or bear–market.

John F. Ehlers speaks internationally on the subject of cycles in the market and has expanded the scope of his contributions to technical analysis through the application of scientific digital signal processing techniques.
