The present invention comprises a method using cellular automata to process existing trading data from traders to generate unprecedented output that improves a wide range of future financial trading decisions and alerts for both individual traders and institutions. However, the method and system of the present invention is not a predictive system based on input of market data and it is not algorithmic. Rather, the method and system instead uses cellular automata logic to mimic human trading behavior. Based on the observations of human trading behavior decisions, the present invention generates an output of buy and sells decisions or simply an alert signal. This use of cellular automata as a basis for evaluating trading behavior provides a different basis for generating trading decisions and alerts and forms a new class of financial alerts over the prior art. The method of using cellular automata logic to process financial trading signals is therefore a paradigm shift in the logic behind trading decisions and alerts. It creates a new kind of technical analysis that features cellular automata interacting with human traders and data.
