Chart patterns or Chaos attractors?
All the chart patterns can be analyzed as attractors. Sensitivity to initial conditions means that each point in such a system is arbitrarily closely approximated by other points with significantly different future trajectories. Thus, an arbitrarily small perturbation of the current trajectory may lead to significantly different future behavior.
In practice a powerful spike even it is corrected will influence the future price action and will set a new set of solutions. If a spike modifies the current phase space (current volatility) it is a signal that the system will be perturbed.
In practice we can analyze the beginning and the end of the market periods.
Let look what happened in the Euro.
For example when we had a powerful trend in September that state was set be the initial conditions. Unless they were not perturbed they set particular attractors that were working. In this case the trend was so simple that it was unbelievable how simple trading can be. But some people did not make money because they cannot believe that and countered the trend for a reversal.
After that Happened in October a break - out in the European session that was directed downwards. What did that mean? That means that the structure of the market has been perturbed. The market started to make another type of patterns: oscillating patterns.
In November this week a powerful shift and spike has occurred. This spike perturbed the structure of the chaotic attractors (cyclic type of patters with nice swings ). The subsequent break - out upwards was a part of the new structure and will participate in the new chaotic attractor that will emerge.
So we can analyze the price action as chaotic attractors in a particular phase space. What is important to know when a powerful shift in the structure occurs. We cannot know how, when, and why and that cannot be predicted. You can analyze that by your experience or you can use an algorithm (like this which is posted on this blog).
The most common errors that is made by the technicians is when a powerful shift in the structure occurs they try to use a pattern that was in force before.
That is a point when the complex neural net models fail, because they are used for a structure that is not anymore valid and a new structure is about to emerge.
This is just a theory guys and gals. But the calculation of the Hurst exponent showed a clear long term process in the markets. The lyapunov exponents calculations showed that even sometimes the processes are really not dissipative.
