中文简介: | 暗池是一种相对较新的股票交易类型,在这种交易中,为了最大限度地减少大宗交易对市场的影响,有意限制透明度。暗池的成功和扩散也导致了算法交易中一个具有挑战性和有趣的问题,即优化大型交易在多个竞争暗池上的分布。在这项工作中,我们将其形式化为一个从审查数据进行多地点探索的问题,并为其解决方案提供了一个可证明有效和接近最优的算法。该算法及其分析与已有研究的加强学习勘探开发算法有很多相同之处,并对大型经纪公司的暗池执行数据进行了评估。 |
课程简介: | Dark pools are a relatively recent type of equities exchange in which transparency is deliberately limited in order to minimize the market impact of large-volume trades. The success and proliferation of dark pools has also led to a challenging and interesting problem in algorithmic trading --- namely, optimizing the distribution of a large trade over multiple competing dark pools. In this work we formalize this as a problem of multi-venue exploration from censored data, and provide a provably efficient and near-optimal algorithm for its solution. This algorithm and its analysis has much in common with well-studied algorithms for exploration-exploitation in reinforcement learning, and is evaluated on dark pool execution data from a large brokerage. |
