限价订单簿的深度学习

Deep Learning for Limit Order Books

Justin Sirignano

摘要:

本文开发了一种新的神经网络架构,用于建模空间分布(即,分布),其在计算上是高效的并且被专门设计为利用限价订单簿的空间结构。新架构产生深入到限价订单簿中的价格运动的低维模型,允许更有效地使用来自限价订单簿中的信息(即,超出最佳出价和最佳要价的许多级别)。该“空间神经网络”以限价订单簿的当前状态为条件,对限价订单簿的状态在未来时间的联合分布进行建模。空间神经网络优于其他模型,如朴素经验模型,逻辑回归(具有非线性特征)和标准神经网络架构。这两种神经网络的性能都大大优于逻辑回归模型。由于空间神经网络更有效地利用了限价订单簿中的深层信息,其在分布尾部的表现尤其优于标准神经网络,这对风险管理应用具有重要意义。这些模型在近500种股票上进行了训练和测试。采用深度学习技术(如dropout)来提高性能。由于与大量数据相关的重大计算挑战,模型使用50个GPU的集群进行训练。

英文摘要:

This paper develops a new neural network architecture for modeling spatial distributions (i.e., distributions on R^d) which is computationally efficient and specifically designed to take advantage of the spatial structure of limit order books. The new architecture yields a low-dimensional model of price movements deep into the limit order book, allowing more effective use of information from deep in the limit order book (i.e., many levels beyond the best bid and best ask). This "spatial neural network" models the joint distribution of the state of the limit order book at a future time conditional on the current state of the limit order book. The spatial neural network outperforms other models such as the naive empirical model, logistic regression (with nonlinear features), and a standard neural network architecture. Both neural networks strongly outperform the logistic regression model. Due to its more effective use of information deep in the limit order book, the spatial neural network especially outperforms the standard neural network in the tail of the distribution, which is important for risk management applications. The models are trained and tested on nearly 500 stocks. Techniques from deep learning such as dropout are employed to improve performance. Due to the significant computational challenges associated with the large amount of data, models are trained with a cluster of 50 GPUs.
