The MYFORANS Model is used today to trade futures, liquid stocks and major currency pairs, mostly intra-day. All current users are professional traders working in Swiss banks trading rooms. The MYFORANS Model is based on concepts derived from physics with main contributions coming from the following fields: chaos theory, theory of complexity, fractals and flow dynamics. Traditional approaches based on statistics and data series crunching have been discarded. Neural networks, fuzzy logic, pattern recognition and other AI techniques have been also abandoned to privilege a general theory applicable to any highly interactive phenomenon. The only input of the Model are tick-by-tick prices and related volumes. The market, or specific asset, “fundamentals” are completely overlooked and, as such, it can be said that the Model is Greed-and-Fear driven.
