We introduce a new method for quantifying pattern-based complex short-time correlations of a time series. Our correlation measure is 1 for a perfectly correlated and 0 for a random walk time series. When we apply this method to high-frequency time series data of the German DAX future, we find clear correlations on short time scales. In order to subtract trivial autocorrelation parts from the pattern conformity, we introduce a simple model for reproducing the antipersistent regime and use… 

Econophysics — complex correlations and trend switchings in financial time series

Abstract This article focuses on the analysis of financial time series and their correlations. A method is used for quantifying pattern based correlations of a time series. With this methodology,

Trend Switching Processes in Financial Markets

For an intriguing variety of switching processes in nature, the underlying complex system abruptly changes at a specific point from one state to another in a highly discontinuous fashion. Financial

Quantifying meta-correlations in financial markets

Financial markets are modular multi-level systems, in which the relationships between the individual components are not constant in time. Sudden changes in these relationships significantly affect

How High Frequency Trading Affects a Market Index

It is found that in short time scales stocks have a stronger influence on the index, and the price of an index should be published on shorter time scales, as close as possible to those of the actual transaction time scale.

Switching processes in financial markets

It is suggested that the well known catastrophic bubbles that occur on large time scales—such as the most recent financial crisis—may not be outliers but single dramatic representatives caused by the formation of increasing and decreasing trends on time scales varying over nine orders of magnitude from very large down to very small.

Accelerated Fluctuation Analysis by Graphic Cards and Complex Pattern Formation in Financial Markets

The compute unified device architecture is an almost conventional programming approach for managing computations on a graphics processing unit (GPU) as a data-parallel computing device. With a

Linking agent-based models and stochastic models of financial markets

This work constructs an agent-based model to quantitatively demonstrate that “fat” tails in return distributions arise when traders share similar technical trading strategies and decisions and derives and explains a set of quantitative scaling relations of long-term memory from the empirical behavior of individual market participants.



Universal and Nonuniversal Properties of Cross Correlations in Financial Time Series

We use methods of random matrix theory to analyze the cross-correlation matrix C of price changes of the largest 1000 US stocks for the 2-year period 1994-95. We find that the statistics of most of

Noise Dressing of Financial Correlation Matrices

We show that results from the theory of random matrices are potentially of great interest to understand the statistical structure of the empirical correlation matrices appearing in the study of price

Scaling of the distribution of fluctuations of financial market indices.

Estimates of alpha consistent with those describing the distribution of S&P 500 daily returns are found, and for time scales longer than (deltat)x approximately 4 d, the results are consistent with a slow convergence to Gaussian behavior.

Quantitative model of price diffusion and market friction based on trading as a mechanistic random process.

It is shown that even under completely random order flow the need to store supply and demand to facilitate trading induces anomalous diffusion and temporal structure in prices.

An Introduction to Econophysics: Correlations and Complexity in Finance

Economists and workers in the financial world will find useful the presentation of empirical analysis methods and well-formulated theoretical tools that might help describe systems composed of a huge number of interacting subsystems.

Optimal execution strategies in limit order books with general shape functions

This work builds on the resilience model proposed by Obizhaeva and Wang (2005) but allows for a general shape of the LOB defined via a given density function, and obtains a new closed-form representation for the optimal strategy of a risk-neutral investor.
