Inter-burst times of the empirical high-frequency financial market data and non-linear stochastic models — •Aleksejus Kononovicius and Vygintas Gontis — Institute of Theoretical Physics, Vilnius University, Vilnius, Lithuania

Recently we have proposed a non-linear stochastic model of return and trading activity in financial markets reproducing power law probability and spectral densities [1]. The reproduced statistical properties are in agreement with the high frequency empirical data. The proposed class of nonlinear stochastic differential equations is also known to exhibit power law bursting behavior [2,3], while similar behavior is also observed in the empirical data of financial markets [3]. In this contribution we will extend our previous approaches to the burst statistics by considerably more detailed analyses of the modelic and empirical inter-burst time durations.
