What is the RSL indicator ?

the RSL indicator was developed in from Robert A. Levy in 1960s and was published in a book "The Relative Strength Concept Of Common Stock Price Forecasting" at investors intelligence inc. Larchmont, New York, 1969. Sometimes the RSL is mixed up with the "Relative Strength Index" developed by Wilder but these two are different indicators. The indicator is the weekly close price divided by the last 27 weeks moving average (RSL = weekly close / last 27 weeks moving average). In germany Ralf Goerke has developed a worldwide market indicator called "the exchange momentum indicator" which is able to make a weather forecast of all the global markets based on the RSL indicator of Robert A. Levy. This great achievement of such a weather forecast from Mr. Goerke is for me the most interesting and important work in technical analysis in this decade. It doesen,t matter if we trade stocks, currencies or futures this indicator can give us a very clear market view. This is a very sophisticated market indicator easy to apply telling us to be or not to be in the markets we trade. Mr. Goerke at this time is writing on his first book about the application of his studies of the RSL indicator. The book from Mr. Goerke will be soon availabe at the beginning of 2008 in his first edition in german language.
