高频市场的微观结构

The microstructure of high frequency markets

Rene Carmona, Kevin Webster

摘要:

我们提出了一种新的方法来描述的微观结构的高频交易使用两个关键要素。首先,我们引入了一个新的概念,知情交易者,我们鲜明对比,目前知情交易者模型。我们描述的确切性质的“优越的信息”高频交易者有机会,以及如何这些代理商不同,从更标准的“内幕交易者”在过去的文件中描述。然后,这导致了一个模型和实证分析的数据,有力地支持我们的主张。第二个关键要素是对限价订单簿上的清算条件的严格描述,以及如何为这样的市场推导出正确的公式。从理论的角度来看,这使得能够准确地确定市场中的两种摩擦,其中之一与我们的“优越信息”概念密切相关。根据经验,我们发现,忽略这些摩擦可能会歪曲市场上交换的财富的50%。最后,我们展示了我们的方法的两个应用程序:我们衡量的利润,高频交易商在纳斯达克和重新访问标准的布莱克-斯科尔斯模型,以确定如何贸易摩擦改变三角洲对冲策略。

英文摘要:

We present a novel approach to describing the microstructure of high frequency trading using two key elements. First we introduce a new notion of informed trader which we starkly contrast to current informed trader models. We describe the exact nature of the `superior information' high frequency traders have access to, and how these agents differ from the more standard `insider traders' described in past papers. This then leads to a model and an empirical analysis of the data which strongly supports our claims. The second key element is a rigorous description of clearing conditions on a limit order book and how to derive correct formulas for such a market. From a theoretical point of view, this allows the exact identification of two frictions in the market, one of which is intimately linked to our notion of `superior information'. Empirically, we show that ignoring these frictions can misrepresent the wealth exchanged on the market by 50%. Finally, we showcase two applications of our approach: we measure the profits made by high frequency traders on NASDAQ and re-visit the standard Black - Scholes model to determine how trading frictions alter the delta-hedging strategy.
