Ian was born in Australia, but moved permanently to Canada in 1974, where he made his name in technical analysis. He created what became known as the Trend & Cycle Department at a major investment house. In the late 1980’s he went out on his own, forming Yelton Fiscal to become an independent research provider.
Ian was also one of the founders of both the CSTA (Canadian Society of Technical Analysts) and IFTA, and was the creator of the Walkabout sessions at IFTA conferences.
Ian died in May 2008, and in partnership with the MTA Educational Foundation, the Ian S Notley Memorial Award on Cycles Research was inaugurated in 2010.
