限价订单簿动态的多智能体模型

A Multi Agent Model for the Limit Order Book Dynamics

Marco Bartolozzi

摘要:

在目前的工作中,我们引入了一种新的多智能体模型,其目的是通过忠实地模拟限价订单簿中的匹配机制,在微观时间尺度上再现双向拍卖市场的动态。代理遵循噪声决策过程,他们的行动与随机变量“市场情绪”有关,我们将其定义为公共和私人信息的混合物。该模型,尽管对代理人的交易策略只做了一些基本假设,但它能够再现市场微观结构的高频动态的几个经验特征,这些特征不仅与价格走势有关,而且与订单在书中的沉积有关。

英文摘要:

In the present work we introduce a novel multi-agent model with the aim to reproduce the dynamics of a double auction market at microscopic time scale through a faithful simulation of the matching mechanics in the limit order book. The agents follow a noise decision making process where their actions are related to a stochastic variable, "the market sentiment", which we define as a mixture of public and private information. The model, despite making just few basic assumptions over the trading strategies of the agents, is able to reproduce several empirical features of the high-frequency dynamics of the market microstructure not only related to the price movements but also to the deposition of the orders in the book.
