Definition of Attractor: An attractor is a kind of steady state in a dynamical system There are three types of attractor: stable steady states, cyclical attractors, and chaotic attractors (Econterms) Terms related to Attractor: Steady states Cyclical attractors Chaotic attractors About Com Resources on Attractor: None Writing a Term Paper?

According to me (Sunny Harris) and attractor is a magnetic force that pushes and pulls the market prices toward it There are always attractors at other levels pulling in the opposite direction, so that accounts for the pushing away from part of the definition In my way of looking at the market, support and resistance lines drawn from previous price points can be attractors Top, bottom and midline Bollinger Bands can be attractors The 200-day and 50-day moving averages are attractors Attractors are places where buys or sellers have lived before and will jump into action when price gets to that level
an entertainer who attracts large audiences; "he was the biggest drawing card they had"
(physics) a point in the ideal multidimensional phase space that is used to describe a system toward which the system tends to evolve regardless of the starting conditions of the system
a characteristic that provides pleasure and attracts; "flowers are an attractor for bees"
A point to which a system tends to move, a goal, either deliberate or constrained by system parameters (laws) The three permanent attractor types are fixed point, cyclic and strange (or chaotic)
An attractor is a trajectory of a dynamical system such that initial conditions nearby it will tend toward it in forward time Often called a stable attractor but this is redundant
A set of points or states to which a dynamical system evolves after a long enough time. That is, points that get close enough to the attractor remain close even if slightly disturbed
If you plot one variable against another for a series of times, the successive points may seem to move along a trajectory, often a cyclical one This phase portrait may well look like an oddly-shaped orbit around an imaginary gravitational attractor, from whence the name All of my chaotic illustrations are in such a phase space There are four general classes of attractors: point (say, the neuron's resting state), periodic (as in pacemaker cells), quasi-periodic, and chaotic The magnets in my loopy illustrations serve as a stand-in for a quasi-periodic attractor, as would an organ pipe Whereas pipes have well-defined harmonics, chaotic attractors have overtones everywhere, in the manner of white noise Chaotic systems are highly sensitive to initial conditions; while somewhat predictable in the short run, they may do surprising things in the long run [66]
A stable equilibrium state having the property that small departures from the equilibrium continually diminish An attractor may be represented in a coordinate system as a single point (the usual case) or as a bounded set of infinitely many points (as in the case of a limit cycle) A strange attractor is an attractor containing an infinite number of points and having the property that small changes in neighboring states give rise to large and apparently unpredictable changes in the evolution of the system The best-known example of a strange attractor in meteorology is that discovered by E N Lorenz (1963) in solutions to a simplified set of equations describing the motion of air in a horizontal layer heated from below Lorenz, E N , 1963: Deterministic nonperiodic flow J Atmos Sci , 20, 130141
