We show using nonlinear time series analysis that the timing of trades in foreign exchange markets has significant information. We apply a set of methods for analyzing point process data developed in neuroscience and nonlinear science. Our results imply that foreign exchange markets might be chaotic and have short-term predictability.
For the last fifteen years, high-resolution foreign exchange data have been successfully characterized using techniques developed in econophysics , , , , , , , , , ,  and . Although price changes, the distribution of inter-trade intervals, and numbers of trades per unit time were intensively studied, the timing of trades is often assumed to be stochastic and has not been thoroughly investigated from a viewpoint of nonlinear dynamics. Here we report that trade times also provide fundamental information about foreign exchange markets. By applying techniques developed in neuroscience  and , we show that trade times do not follow the Poisson process and that they provide some information which cannot be obtained from short-term counts of trade times. Applications of the recently developed distance  for marked point processes with methods ,  and  in nonlinear science suggest that trades have serial dependence and that their generating process can be deterministically chaotic. Actually series of trades can be predicted for a short term. The results imply that by taking into account the timing of trades, the dynamics of foreign exchange markets may be controlled by chaos control .
