📝 摘要(中文)
在现代金融市场中,超过四分之三的大宗交易由算法交易执行,这些交易依赖于先进的交易策略以实现比传统人类交易者更高的精度和速度。传统的基于价格的策略无法有效捕捉由社会情绪、政治不稳定或突发经济变化等现实事件引起的市场动态。随着深度强化学习(DRL)和数据可用性的提升,迫切需要更高效的算法来将这些外部因素纳入交易策略中。本文提出了一种基于部分和深度情感分析的DRL方法,采用了不同的策略设计,包括仅优化策略的A2C和PPO,以及结合Q学习原则的DDPG、TD3和SAC。研究结果表明,结合Q学习的策略优化代理在利润最大化和风险规避交易方面表现出显著且一致的性能提升。
🔬 方法详解
问题定义:本文旨在解决传统基于价格的交易策略在捕捉市场动态方面的不足,尤其是无法有效应对社会情绪和突发事件的挑战。
核心思路:通过引入情感分析,结合深度强化学习中的策略优化和Q学习原则,设计出能够更好适应市场变化的交易代理。
技术框架:整体架构包括数据预处理、情感分析模块、策略优化模块和Q学习模块,形成一个闭环的交易决策系统。
关键创新:最重要的创新在于将情感分析深度融入到DRL框架中,形成了新的策略设计,显著提升了交易代理的决策能力。
关键设计:在参数设置上,采用了适应性学习率和多层神经网络结构,损失函数设计考虑了风险和收益的平衡,确保了策略的稳定性和有效性。

🎯 应用场景
该研究的潜在应用领域包括高频交易、资产管理和投资组合优化等。通过引入情感分析,交易策略能够更灵活地应对市场波动,提升投资决策的准确性和效率,具有重要的实际价值和未来影响。
📄 摘要(原文)
In modern financial markets, more than 3/4th of the large volume trade is executed by algorithmic trading based on advanced trading strategies to attain higher precision and speed than traditional human traders. The conventional strategies focused on price-based indicators are inadequate in capturing the market dynamism arising from real-world events such as social sentiments, political instability, or sudden economic shifts. With the rise of Deep Reinforcement Learning (DRL) and data availability, there is a requirement for more efficient algorithms that can incorporate these external factors in trading strategies. DRL has shown potential in simulating real-world scenarios and in simplifying complex decision-making since DRL agents can automate the trading process i.e. executing trades in a manner comparable to human traders. They have shown reliable performance since they can update their policies based on risk and quantitative factors. In this paper, we propose a DRL approach based on partial and deep-infusion of sentimental analysis. It features distinct policy designs of actor-critic-based agents: only policy optimization (A2C & PPO) and policy optimization along with Q-learning principles (DDPG, TD3 & SAC). Our findings reveal, that the agents based on policy optimization combined with Q-learning, significantly and consistently demonstrate improved performance upon sentiment deep-infusion in profit maximization as well as risk-averse trading.
