英文摘要:
In this paper we propose a mathematical framework to address the uncertainty emergingwhen the designer of a trading algorithm uses a threshold on a signal as a control. We rely ona theorem by Benveniste and Priouret to deduce our Inventory Asymptotic Behaviour (IAB)Theorem giving the full distribution of the inventory at any point in time for a well formulatedtime continuous version of the trading algorithm.Since this is the first time a paper proposes to address the uncertainty linked to the use of athreshold on a signal for trading, we give some structural elements about the kind of signals thatare using in execution. Then we show how to control this uncertainty for a given cost function.There is no closed form solution to this control, hence we propose several approximation schemesand compare their performances.Moreover, we explain how to apply the IAB Theorem to any trading algorithm drivenby a trading speed. It is not needed to control the uncertainty due to the thresholding of asignal to exploit the IAB Theorem; it can be applied ex-post to any traditional trading algorithm.

中文摘要:
在本文中,我们提出了一个数学框架来解决交易算法设计者使用信号阈值作为控制时出现的不确定性。我们依靠Benveniste和Priouret的一个定理来推导我们的库存渐近行为(IAB)定理,该定理给出了交易算法的一个公式化的时间连续版本在任何时间点的库存的完整分布。由于这是第一次有论文提出解决与在交易信号上使用athreshold相关的不确定性,我们给出了执行中使用的信号类型的一些结构要素。然后,我们展示了如何控制给定成本函数的这种不确定性。该控制没有封闭形式的解,因此我们提出了几种近似方案并比较了它们的性能。此外,我们还解释了如何将IAB定理应用于任何由交易速度驱动的交易算法。利用IAB定理,不需要控制信号阈值的不确定性;它可以事后应用于任何传统的交易算法。
