潜在的流动性是如何在限价订单簿中显现出来的?

How does latent liquidity get revealed in the limit order book?

摘要:

潜在订单簿模型使我们对金融市场价格形成的理解取得了重大进展。特别是他们能够重现一些程式化的事实,如平方根影响定律。一个重要的问题是,如果要使这种模型更接近真实的市场数据,那就是潜在的(不可观察的)订单簿和真实的(可观察的)订单簿之间的联系。在这里,我们提出了一个简单的,一致的机制,潜在的流动性,允许定量估计潜在的订单簿从真实的市场数据的启示。我们成功地将我们的结果与超过100种资产的真实订单簿数据进行了对比,并讨论了市场稳定性。我们的一个重要理论结果是存在一个市场不稳定阈值,在这个阈值下,潜在订单的转换变得太慢,从而引发流动性危机。最后,我们计算的价格影响的元订单在不同的参数制度。

英文摘要:

Latent order book models have allowed for significant progress in our understanding of price formation in financial markets. In particular they are able to reproduce a number of stylized facts, such as the square-root impact law. An important question that is raised -- if one is to bring such models closer to real market data -- is that of the connection between the latent (unobservable) order book and the real (observable) order book. Here we suggest a simple, consistent mechanism for the revelation of latent liquidity that allows for quantitative estimation of the latent order book from real market data. We successfully confront our results to real order book data for over a hundred assets and discuss market stability. One of our key theoretical results is the existence of a market instability threshold, where the conversion of latent order becomes too slow, inducing liquidity crises. Finally we compute the price impact of a metaorder in different parameter regimes.
