Elliott wave theory and neuro-fuzzy systems, in stock market prediction: the WASP systemElliott wave theory and neuro-fuzzy systems, in stock market prediction: the WASP system Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-072011enThis paper presents the WASP (Wave Analysis Stock Prediction) system, a system based on the neuro-fuzzy architecture, which utilizes aspects from the Elliott Wave Theory, presented by Ralph Nelson Elliott. This theory has been found to be extremely useful and accurate, particularly in problems of forecasting. A neuro-fuzzy logic technique has been used to forecast the trend of the stock prices and the results derived are very encouraging.http://creativecommons.org/licenses/by/4.0/Expert Systems with Applications3889196-9206 Atsalakis Georgios Ατσαλακης Γεωργιος Dimitrakakis Emmanouil M.
