FinRL: A Deep Reinforcement Learning Library for Automated Stock Trading in Quantitative Finance
The paper presents FinRL, a deep reinforcement learning library specifically designed to democratize access to automated stock trading strategies in quantitative finance. Recognizing that developing practical DRL trading agents involves complex decisions about trading locations, prices, and quantities along with arduous debugging processes, FinRL addresses these challenges by providing a comprehensive framework that simplifies the development pipeline. The library features a modular architecture with pre-configured virtual environments using real stock market data, implementations of state-of-the-art DRL algorithms, and incorporates important trading constraints such as transaction costs, market liquidity, and investor risk preferences.
FinRL distinguishes itself through three key features: completeness across multiple time granularities and stock markets, hands-on tutorials that promote learning, and strong reproducibility that allows easy comparison with existing schemes. The library supports various trading scenarios including single stock trading, multiple stock trading, and portfolio allocation, making it versatile for different quantitative finance applications. By providing standardized evaluation baselines and user-friendly interfaces, FinRL significantly reduces the barrier to entry for beginners while maintaining the flexibility needed for advanced research and development in automated trading systems.
