英文摘要:
In spite of the growing consideration for optimal execution in the financial mathematics literature, numerical approximations of optimal trading curves are almost never discussed. In this article, we present a numerical method to approximate the optimal strategy of a trader willing to unwind a large portfolio. The method we propose is very general as it can be applied to multi-asset portfolios with any form of execution costs, including a bid-ask spread component, even when participation constraints are imposed. Our method, based on convex duality, only requires Hamiltonian functions to have $C^{1,1}$ regularity while classical methods require additional regularity and cannot be applied to all cases found in practice.

中文摘要:
尽管金融数学文献中对最优执行的考虑越来越多,但几乎从未讨论过最优交易曲线的数值近似。在这篇文章中,我们提出了一个数值方法来近似的最佳策略的交易者愿意解除一个大的投资组合。我们提出的方法非常通用,因为它可以应用于具有任何形式执行成本的多资产投资组合,包括买卖价差部分,即使在施加参与约束的情况下也是如此。我们的方法基于凸对偶,只要求哈密顿函数具有$C^{1,1}$正则性,而经典方法需要额外的正则性,不能适用于实践中发现的所有情况。
