潜在订单簿中的市场冲击

Market Impact in a Latent Order Book

Ismael Lemhadri

摘要:

\cite{donier2015fully}的潜在订单簿是基于Agent的市场冲击模型中最有前途的一种。这项工作扩展了最小模型,允许代理人表现出均值回归,在现实市场中常见的模式。这种修改导致新的订单簿动态,我们明确研究和分析。我们的分析是基于一个平均场假设,通过\textit{average}密度来观察订单簿。我们展示了价格影响如何在这个新模型中发展,提供了一系列灵活的解决方案,可以潜在地改善对真实数据的校准。虽然没有提供封闭形式的解决方案,我们补充我们的理论研究与广泛的数值结果,包括整个订单簿的模拟计划。

英文摘要:

The latent order book of \cite{donier2015fully} is one of the most promising agent-based models for market impact. This work extends the minimal model by allowing agents to exhibit mean-reversion, a commonly observed pattern in real markets. This modification leads to new order book dynamics, which we explicitly study and analyze. Underlying our analysis is a mean-field assumption that views the order book through its \textit{average} density. We show how price impact develops in this new model, providing a flexible family of solutions that can potentially improve calibration to real data. While no closed-form solution is provided, we complement our theoretical investigation with extensive numerical results, including a simulation scheme for the entire order book.
