英文摘要:
We study the optimal placement problem of a stock trader who wishes to clear his/her inventory by a predetermined time horizon t, by using a limit order or a market order. For a diffusive market, we characterize the optimal limit order placement policy and analyze its behavior under different market conditions. In particular, we show that, in the presence of a negative drift, there exists a critical time t0>0 such that, for any time horizon t>t0, there exists an optimal placement, which, contrary to earlier work, is different from one that is placed \"infinitesimally\" close to the best ask, such as the best bid and second best bid. We also propose a simple method to approximate the critical time t0 and the optimal order placement.

中文摘要:
我们研究了一个股票交易者的最优配售问题,该交易者希望在预定的时间范围t内,通过使用限价指令或市场指令结算其库存。对于一个扩散市场,我们刻画了最优限价订单安排策略,并分析了其在不同市场条件下的行为。特别是,我们表明,在存在负漂移的情况下,存在一个临界时间t0>0,这样,对于任何时间范围t>t0,都存在一个最优位置,这与早期的工作相反,不同于“无限小”接近最佳ask的位置,如最佳出价和次最佳出价。我们还提出了一种简单的方法来近似临界时间t0和最优订单安排。
