1. Multilevel Process Analysis – Why? How? • Why ?Under the Multilevel Dynamic Market Hypothesis and as a matter of fact, multilevel stochastic dynamic processes of market prices simply exist, and they are either irreducible or not effectively reducible to any single-level process. • How ?Multilevel Stochastic Dynamic Process (MSDP) Models of Financial Time Series- Multilevel Fractal Decomposition of Financial Time Series- Multilevel Structural Time Series Models- Multilevel Stochastic Differential Equations- Multilevel Nonlinear Process Pattern Models- Multilevel Nonparametric Kernel Regression Models- Multilevel Markov Chain of Intermittent Chaos Models www.swingtum.com/institute/IWIF
2. Facts and Assumptions underlying MPA(Dow 1880’s, Graham 1930’s; Elliott 1930’s, Mandelbrot 1970-2004; Peters, 1991; Dacorogna et al, 2001; Pan 2003-2006) • Heterogeneous Market Hypothesis: Market participants are not homogeneous; there are producers, hedgers, investors, traders and speculators; different participants react to the same information in different ways with these characteristics:- Different participants have different time horizons and dealing frequencies;- Different participants are likely to settle for different prices and decide to execute their transactions in different situations, so they create volatility;- The market is also heterogeneous in industrial and financial sectors and in the geographic location of the participants. • Fractal Market Hypothesis: Different participants with different time horizons and dealing frequencies share the same human nature, consequently the market prices exhibit a fractal structure. • Multilevel Dynamic Market Hypothesis: (Swingtum Market Hypothesis)The fractal market prices exhibit robust stochastic dynamic patterns in the scale space of time and price, which can be described in terms of multilevel trends, swings and momentums. www.swingtum.com/institute/IWIF

Multilevel Fractal Decomposition of Financial Time Series There are three possible approaches: • Multilevel Fractal Extraction with Geometrical Ratio Series(Multilevel Zigzag Transformation using Fibonnaci Ratios)[0.6180, 0.3820, 0.2361, 0.1459, 0.0902, 0.0557, 0.0344, 0.0213, 0.0132] • Multilevel Top-Down Time Series Generalization(adapted from Duda & Hart, 1960’s, and Pan & Förstner 1991) • Multilevel Bottom Up Empirical Mode Decomposition (EMD)(Hilbert-Huang Transform, 1998) www.swingtum.com/institute/IWIF

A Dynamical Microeconomic Model of Caginalp and Balenovich (2003) Classical theory of adjustment: stipulates that relative price change occurs in order to restore a balance between supply S and demand D, which in turn depend on price with Augmentation by Caginalp and Balenovich (2003): supply and demand depend not only on price, but also on price derivative, so oscillations are introduced. www.swingtum.com/institute/IWIF
and Assume a single group of traders with the total assets limited and normalized to 1 = B (in stocks) + (1-B) (in cash). Let k be the probability or rate at which cash flows into stock. An analysis of asset flow on the conservation of the total capital implies A specific form of the price equation www.swingtum.com/institute/IWIF
Probability k [0, 1] is a function of the total investor sentiment ζ(-∞, +∞) which is the sum of ζ1 the trend-based preference and ζ2 the value-based preference. Let Pa denote the fundamental value, q the amplitude, c a measure of the time scale or “memory length” of the trend (or the value). ζ1 and ζ2 can be expressed as EMA of the trend and the relative discount of the value. and www.swingtum.com/institute/IWIF
