英文摘要:
A microscopic model is established for financial Brownian motion from the direct observation of the dynamics of high-frequency traders (HFTs) in a foreign exchange market. Furthermore, a theoretical framework parallel to molecular kinetic theory is developed for the systematic description of the financial market from microscopic dynamics of HFTs. We report first on a microscopic empirical law of traders\' trend-following behavior by tracking the trajectories of all individuals, which quantifies the collective motion of HFTs but has not been captured in conventional order-book models. We next introduce the corresponding microscopic model of HFTs and present its theoretical solution paralleling molecular kinetic theory: Boltzmann-like and Langevin-like equations are derived from the microscopic dynamics via the Bogoliubov-Born-Green-Kirkwood-Yvon hierarchy. Our model is the first microscopic model that has been directly validated through data analysis of the microscopic dynamics, exhibiting quantitative agreements with mesoscopic and macroscopic empirical results.

中文摘要:
通过对外汇市场高频交易者动态的直接观察,建立了金融布朗运动的微观模型。此外,还建立了一个与分子动力学理论平行的理论框架,以便从HFTs的微观动力学系统地描述金融市场。我们首先通过跟踪所有个体的轨迹,报告了交易员趋势跟踪行为的微观经验法则,该法则量化了高频交易的集体运动,但在传统的订单簿模型中尚未捕捉到。接下来,我们介绍了相应的HFTs微观模型,并给出了其平行于分子动力学理论的理论解:类Boltzmann和类Langevin方程是通过Bogoliubov-Born-Green-Kirkwood-Yvon层次从微观动力学推导出来的。我们的模型是第一个通过微观动力学
数据分析直接验证的微观模型,显示出与介观和宏观经验结果的定量一致性。
