英文摘要:
We study a linear price impact model including other liquidity takers, whose flow of orders either follows a Poisson or a Hawkes process. The optimal execution problem is solved explicitly in this context, and the closed-formula optimal strategy describes in particular how one should react to the orders of other traders. This result enables us to discuss the viability of the market. It is shown that Poissonian arrivals of orders lead to quite robust Price Manipulation Strategies in the sense of Huberman and Stanzl. Instead, a particular set of conditions on the Hawkes model balances the self-excitation of the order flow with the resilience of the price, excludes Price Manipulation Strategies and gives some market stability.

中文摘要:
我们研究了一个包含其他流动性接受者的线性价格影响模型,这些接受者的订单流要么遵循泊松过程,要么遵循霍克斯过程。在这种情况下,最优执行问题得到了明确的解决,封闭式最优策略特别描述了一个人应该如何对其他交易者的指令做出反应。这个结果使我们能够讨论市场的可行性。研究表明,在Huberman和Stanzl的意义上,订单的泊松到达导致了相当稳健的价格操纵策略。相反,霍克斯模型中的一组特定条件平衡了订单流的自激性和价格的弹性,排除了价格操纵策略,并提供了一定的市场稳定性。
