日内市场最优订单执行:交易轨迹成本最小化

Optimal Order Execution in Intraday Markets: Minimizing Costs in Trade Trajectories

Christopher Kath, Florian Ziel

摘要:

最优执行,即,多年来,确定在连续交易时段中交易量的最具成本效益的方式一直是股票交易界感兴趣的话题。电力日内交易缓慢地遵循这一趋势,但远未得到充分研究。根本问题是一个非常复杂的问题。能源交易商、生产商和电力批发公司从客户企业、可再生能源生产或工厂停电接收各种头寸更新,并需要在日内市场交易这些头寸。他们有各种各样的选择,当谈到位置大小或时间。是不是一次性交易所有金额更好?他们应该把订单分成更小的部分吗?本文以德国连续小时日内市场为例,推导出适合电力交易的模型。我们展示了样本外研究的结果,并区分了简单的基准模型和我们更精细的优化方法,该方法考虑了订单簿深度、交货时间和不同的交易制度,如XBID(跨境日内项目)交易。我们的论文具有高度相关性,因为它有助于进一步深入了解连续日内市场中算法执行的学术讨论,并为从业者提供指导。我们的初步结果表明,最优执行策略有相当大的货币影响。

英文摘要:

Optimal execution, i.e., the determination of the most cost-effective way to trade volumes in continuous trading sessions, has been a topic of interest in the equity trading world for years. Electricity intraday trading slowly follows this trend but is far from being well-researched. The underlying problem is a very complex one. Energy traders, producers, and electricity wholesale companies receive various position updates from customer businesses, renewable energy production, or plant outages and need to trade these positions in intraday markets. They have a variety of options when it comes to position sizing or timing. Is it better to trade all amounts at once? Should they split orders into smaller pieces? Taking the German continuous hourly intraday market as an example, this paper derives an appropriate model for electricity trading. We present our results from an out-of-sample study and differentiate between simple benchmark models and our more refined optimization approach that takes into account order book depth, time to delivery, and different trading regimes like XBID (Cross-Border Intraday Project) trading. Our paper is highly relevant as it contributes further insight into the academic discussion of algorithmic execution in continuous intraday markets and serves as an orientation for practitioners. Our initial results suggest that optimal execution strategies have a considerable monetary impact.
