摘要
Market making is a fundamental trading problem in which an agent provides liquidity by continually o ering to buy and sell a security. The problem is challenging due to inventory risk, the risk of accumulating an unfavourable position and ultimately losing money. In this paper, we develop a high- delity simulation of limit order book markets, and use it to design a market making agent using temporal-di erence reinforcement learning. We use a linear combination of tile codings as a value function approximator, and design a custom reward function that controls inventory risk. We demonstrate the e ectiveness of our approach by showing that our agent outperforms both simple benchmark strategies and a recent online learning approach from the literature.(论文在文章末尾获取)
前言
The role of a market maker is to provide liquidity by facilitating transactions with other market participants. Like many trading problems, it has become increasingly automated since the advent of the electronic limit order book (LOB), as the need to handle more data and act on ever shorter time scales renders the task al- most impossible for humans [25, 29]. Upwards of 60% of trading volume on some particularly active markets has been attributed to automated trading systems [27, 36]. This paper uses reinforce- ment learning (RL) to design competitive market making agents for nancial markets using high-frequency historical equities data.
解读:讲述了做市商的重要性,自从电子限价订单(LOB)出现以来,在一些特别活跃的市场上,60%以上的交易量归功于自动交易系统。本文使用强化学习(RL),利用高频股票历史数据为金融市场设计具有竞争力的making agents。
