英文摘要:
Latency (i.e., time delay) in electronic markets affects the efficacy of liquidity taking strategies. During the time liquidity takers process information and send marketable limit orders (MLOs) to the exchange, the limit order book (LOB) might undergo updates, so there is no guarantee that MLOs are filled. We develop a latency-optimal trading strategy that improves the marksmanship of liquidity takers. The interaction between the LOB and MLOs is modelled as a marked point process. Each MLO specifies a price limit so the order can receive worse prices and quantities than those the liquidity taker targets if the updates in the LOB are against the interest of the trader. In our model, the liquidity taker balances the tradeoff between missing trades and the costs of walking the book. We employ techniques of variational analysis to obtain the optimal price limit of each MLO the agent sends. The price limit of a MLO is characterized as the solution to a new class of forward-backward stochastic differential equations (FBSDEs) driven by random measures. We prove the existence and uniqueness of the solution to the FBSDE and numerically solve it to illustrate the performance of the latency-optimal strategies.

中文摘要:
电子市场中的延迟(即时间延迟)会影响流动性获取策略的有效性。在流动性接受者处理信息并向交易所发送适销限额指令(MLO)的过程中,限额指令簿(LOB)可能会进行更新,因此无法保证MLO已完成。我们制定了一种延迟最优交易策略,以提高流动性接受者的枪法。LOB和MLO之间的交互被建模为标记点过程。每个MLO都指定了一个价格限制,以便在LOB中的更新不符合交易员利益的情况下,订单可以收到比流动性接受者目标更差的价格和数量。在我们的模型中,流动性接受者平衡了缺失交易和照本宣科的成本之间的权衡。我们使用变分分析技术来获得代理发送的每个MLO的最优价格限制。MLO的价格极限是由随机测度驱动的一类新的正倒向随机微分方程(FBSDE)的解。我们证明了FBSDE解的存在性和唯一性,并通过数值求解来说明延迟优化策略的性能。
