从“零智能”到“被动反应”:用于高频波动率估计和最优执行的限价订单簿模型

From Zero-Intelligence to Queue-Reactive: Limit Order Book modeling for high-frequency volatility estimation and optimal execution

Tommaso Mariotti, Fabrizio Lillo, Giacomo Toscano

摘要:

高频数据波动率的估计受到微观结构噪声的困扰,这会导致有偏的测量。替代估计已开发和测试的噪声或其渐近分布的收敛速度的特定结构。Gatheral和Oomen(2010)提出使用限价订单簿的零智能模型来检验几种综合方差估计量的有限样本性能。在此基础上,本文提出了三个主要创新点:(1)将限价订单簿的响应-响应模型作为数据生成过程(Huang et al.(2015)),与零智能模型相比,该模型生成更真实的微观结构动力学,如这里通过使用Hausman测试所示;(ii)我们认为不仅估计的综合波动率,但也现货波动率;(iii)我们显示的相关性估计的预测方差的成本模拟VWAP执行。总体而言,我们发现,对于综合波动率,预平均估计优化的估计偏差,而统一和交替估计导致最佳的均方误差值。相反,在现货波动率的情况下,傅立叶估计器产生最佳精度,无论是在偏差和均方误差方面。后者估计也导致VWAP执行的成本方差的最佳预测。

英文摘要:

The estimation of the volatility with high-frequency data is plagued by the presence of microstructure noise, which leads to biased measures. Alternative estimators have been developed and tested either on specific structures of the noise or by the speed of convergence to their asymptotic distributions. Gatheral and Oomen (2010) proposed to use the Zero-Intelligence model of the limit order book to test the finite-sample performance of several estimators of the integrated variance. Building on this approach, in this paper we introduce three main innovations: (i) we use as data-generating process the Queue-Reactive model of the limit order book (Huang et al. (2015)), which - compared to the Zero-Intelligence model - generates more realistic microstructure dynamics, as shown here by using an Hausman test; (ii) we consider not only estimators of the integrated volatility but also of the spot volatility; (iii) we show the relevance of the estimator in the prediction of the variance of the cost of a simulated VWAP execution. Overall we find that, for the integrated volatility, the pre-averaging estimator optimizes the estimation bias, while the unified and the alternation estimator lead to optimal mean squared error values. Instead, in the case of the spot volatility, the Fourier estimator yields the optimal accuracy, both in terms of bias and mean squared error. The latter estimator leads also to the optimal prediction of the cost variance of a VWAP execution.
