A problem where a large position must be transacted by a risk-averse trader within a short finite horizon is set. A limit order book market is calibrated and simulated, accounting for facts like intraday seasonality, discrete price ticks and round lots, and the distributions of both individual execution cost components and the overall Implementation Shortfall of stylized execution schedules are presented with and without incorporating the order choice decision. Decision rules quantifying the costs, benefits and risks of employing passive limit orders are implemented, optimizing simultaneously the joint decision of pricing, sizing, and duration of each limit order. The improvement in the Implementation Shortfall distribution is significant, in all states of the world, whereas market resiliency, the least researched aspect of market liquidity, is the key location determinant for the Implementation Shortfall distribution. Considerations about imperfect fill and picking-off risks can't outweigh the benefit of trading with patient limit orders.
