Some issues on the stability of trading based on technical analysis

Alvarez-Ramirez, Jose; Fernandez-Anaya, Guillermo; … - In: Physica A: Statistical Mechanics and its Applications 337 (2004) 3, pp. 609-624

Some stability effects of technical trading on financial/commodity markets are analyzed in this paper. Technical … equation, whose (local) stability is determined by means of root-locus techniques. It is proven that the larger the time …-delay horizon, the larger the stability margin. This means that short-run technical trading is more likely to induce market …

Plane-wave solutions of a dissipative generalization of the vector nonlinear Schrödinger equation

Carter, John D. - In: Mathematics and Computers in Simulation (MATCOM) 82 (2012) 6, pp. 1038-1046

The modulational instability of perturbed plane-wave solutions of the vector nonlinear Schrödinger (VNLS) equation is examined in the presence of multiple forms of dissipation. We establish that all constant-magnitude solutions of the dissipative VNLS equation are less unstable than their...

Stability of plane waves on deep water with dissipation

Canney, Nathan E.; Carter, John D. - In: Mathematics and Computers in Simulation (MATCOM) 74 (2007) 2, pp. 159-167

The Benjamin–Feir modulational instability effects the evolution of perturbed plane-wave solutions of the cubic nonlinear Schrödinger equation (NLS), the modified NLS, and the band-modified NLS. Recent work demonstrates that the Benjamin–Feir instability in NLS is “stabilized” when a...

SpectrUW: A laboratory for the numerical exploration of spectra of linear operators

Deconinck, Bernard; Kiyak, Firat; Carter, John D.; … - In: Mathematics and Computers in Simulation (MATCOM) 74 (2007) 4, pp. 370-378

Spectra of linear operators play an important role in various aspects of applied mathematics. For all but the simplest operators, the spectrum cannot be determined analytically and as such it is difficult to build up any intuition about the spectrum. One way to obtain such intuition is to...
