摘要:

我们应用强化学习算法来解决经典的定量金融市场决策问题,在该问题中,代理人通过在最大化效用函数的同时放置买入和卖出订单来为市场提供流动性。最优代理人必须在其库存的价格风险和通过捕捉买卖价差获得的利润之间找到一个微妙的平衡。我们设计了一个环境与奖励函数,决定了一个顺序关系的政策相当于原来的效用函数。当将我们的代理与最佳解决方案和基准对称代理进行比较时,我们发现Deep Q-学习算法能够恢复最佳代理。

英文摘要:

We apply Reinforcement Learning algorithms to solve the classic quantitative finance Market Making problem, in which an agent provides liquidity to the market by placing buy and sell orders while maximizing a utility function. The optimal agent has to find a delicate balance between the price risk of her inventory and the profits obtained by capturing the bid-ask spread. We design an environment with a reward function that determines an order relation between policies equivalent to the original utility function. When comparing our agents with the optimal solution and a benchmark symmetric agent, we find that the Deep Q-Learning algorithm manages to recover the optimal agent.
