J Welles Wilder is known worldwide for his innovative and original concepts in technical trading.

Engineer, turned real estate developer, turned technical analyst, Wilder is credited with developing some of the most widely used and modified technical indicators in the field, from Average True Range to the Parabolic Time/Price System to the Relative Strength Index RSI. His first book, New Concepts in Technical Trading Systems, remains an important reference for both stock and futures traders.

He is probably most well known for developing the RSI (Relative Strength Index) indicator which he first introduced in June 1978.
