英文摘要:
  We introduce a method to infer lead-lag networks of agents\' actions in complex systems. These networks open the way to both microscopic and macroscopic states prediction in such systems. We apply this method to trader-resolved data in the foreign exchange market. We show that these networks are remarkably persistent, which explains why and how order flow prediction is possible from trader-resolved data. In addition, if traders\' actions depend on past prices, the evolution of the average price paid by traders may also be predictable. Using random forests, we verify that the predictability of both the sign of order flow and the direction of average transaction price is strong for retail investors at an hourly time scale, which is of great relevance to brokers and order matching engines. Finally, we argue that the existence of trader lead-lag networks explains in a self-referential way why a given trader becomes active, which is in line with the fact that most trading activity has an endogenous origin.

中文摘要:
我们介绍了一种推断复杂系统中agent行为的超前-滞后网络的方法。这些网络为此类系统的微观和宏观状态预测开辟了道路。我们将此方法应用于外汇市场中的交易员解析数据。我们证明了这些网络是非常持久的,这解释了为什么以及如何从交易者解析的数据中预测订单流。此外,如果交易者的行为取决于过去的价格,那么交易者支付的平均价格的演变也可能是可预测的。使用随机森林,我们验证了在每小时的时间尺度上,对于散户投资者来说,订单流符号和平均交易价格方向的可预测性都很强,这与经纪人和订单匹配引擎有很大的相关性。最后,我们认为交易者超前-滞后网络的存在以一种自我参照的方式解释了为什么给定交易者变得活跃,这与大多数交易活动具有内生起源的事实相一致。
