摘要:

我们引入了一种新的描述金融市场的订单簿的动力学作为一个有效的胶体布朗粒子嵌入流体粒子。全面的市场数据分析使我们能够识别流体颗粒的所有运动。布朗粒子运动与周围流体粒子运动之间的相关性反映了特定的分层相互作用;在内层,相关性较强,具有短记忆性,而在外层,相关性较弱,具有长记忆性。通过解释和估计的贡献,从外层的阻力,我们证明了波动耗散关系(FDR)在这个非物质的布朗运动过程的有效性。

英文摘要:

We introduce a novel description of the dynamics of the order book of financial markets as that of an effective colloidal Brownian particle embedded in fluid particles. The analysis of a comprehensive market data enables us to identify all motions of the fluid particles. Correlations between the motions of the Brownian particle and its surrounding fluid particles reflect specific layering interactions; in the inner-layer, the correlation is strong and with short memory while, in the outer-layer, it is weaker and with long memory. By interpreting and estimating the contribution from the outer-layer as a drag resistance, we demonstrate the validity of the fluctuation-dissipation relation (FDR) in this non-material Brownian motion process.
