FinRL: Deep Reinforcement Learning for Quantitative Finance

Our Mission: to efficiently automate trading. We continuously develop and share codes for finance.

Our Vision: AI community has accumulated an open-source code ocean over the past decade. Applying these intellectual and engineering properties to finance will initiate a paradigm shift from the conventional trading routine to an automated machine learning approach, even RLOps in finance.

FinRL (website) is the first open-source project to explore the great potential of deep reinforcement learning in finance. We help practitioners pipeline a trading strategy using deep reinforcement learning (DRL).

The FinRL ecosystem is a unified framework, including various markets, state-of-the-art algorithms, financial tasks (portfolio management, cryptocurrency trading, high-frequency trading), live trading, etc.

Overview

FinRL has three layers: applications, drl agents, and market environments.

For a trading task (on the top), an agent (in the middle) interacts with an environment (at the bottom), making sequential decisions.

Run FinRL_StockTrading_NeurIPS_2018.ipynb step by step for a quick start.

A video about FinRL library at the AI4Finance Youtube Channel.

File Structure

Correspondingly, the main folder finrl has three subfolders apps, drl_agents, finrl_meta.

We employ a train-test-trade pipeline by three files: train.py, test.py, and trade.py.

Supported Data Sources

OHLCV: open, high, low, and close prices; volume. adj_close: adjusted close price

Technical indicators: 'macd', 'boll_ub', 'boll_lb', 'rsi_30', 'dx_30', 'close_30_sma', 'close_60_sma'. Users also can add new features.

Status Update

Contributions

• FinRL is the first open-source framework to demonstrate the great potential of applying DRL algorithms in quantitative finance. We build an ecosystem around the FinRL framework, which seeds the rapidly growing AI4Finance community.
• The application layer provides interfaces for users to customize FinRL to their own trading tasks. Automated backtesting tool and performance metrics are provided to help quantitative traders iterate trading strategies at a high turnover rate. Profitable trading strategies are reproducible and hands-on tutorials are provided in a beginner-friendly fashion. Adjusting the trained models to the rapidly changing markets is also possible.
• The agent layer provides state-of-the-art DRL algorithms that are adapted to finance with fine-tuned hyperparameters. Users can add new DRL algorithms.
• The environment layer includes not only a collection of historical data APIs, but also live trading APIs. They are reconfigured into standard OpenAI gym-style environments. Moreover, it incorporates market frictions and allows users to customize the trading time granularity.
