New Concepts in Technical Trading Systems

J. Welles Wilder Jr. and the Birth of Popular Indicators

New Concepts in Technical Trading Systems is one of the most innovative books ever written on technical analysis and technical trading. It was first published in 1978, but still remains among the bestsellers 35 years after without any updates.

Its author, J. Welles Wilder Jr., invented numerous tools which are now considered part of the very core of technical analysis – including indicators such as Relative Strength Index (RSI), Average True Range (ATR), Parabolic SAR, and Average Directional Index (ADX/DMI). Much of Wilder’s work was first presented to the world in this book.
