FinRL is an open source library that provides practitioners a unified framework for pipeline strategy development. In reinforcement learning (or Deep RL), an agent learns by continuously interacting with an environment, in a trial-and-error manner, making sequential decisions under uncertainty and achieving a balance between exploration and exploitation. The open source community AI4Finance (to efficiently automate trading) provides educational resources about deep reinforcement learning (DRL) in quantitative finance.

Feel free to report bugs via Github issues, join the mailing list: AI4Finance, and discuss FinRL in slack channel:

Roadmaps of FinRL:

FinRL 1.0: entry-level toturials for beginners, with a demonstrative and educational purpose.

FinRL 2.0: intermediate-level framework for full-stack developers and professionals. Check out ElegantRL

FinRL provides a unified machine learning framework for various markets, SOTA DRL algorithms, benchmark finance tasks (portfolio allocation, cryptocurrency trading, high-frequency trading), live trading, etc.

We implemented Deep Q Learning (DQN), Double DQN, DDPG, A2C, SAC, PPO, TD3, GAE, MADDPG, MuZero, etc. using PyTorch and OpenAI Gym.

# grant access to execute scripting (read it, it's harmless)
$ sudo chmod -R 777 docker/bin

# build the container!
$ ./docker/bin/build_container.sh

# start notebook on port 8887!
$ ./docker/bin/start_notebook.sh

# proceed to party!

Build the container:

$ docker build -f docker/Dockerfile -t finrl docker/

Start the container:

$ docker run -it --rm -v ${PWD}:/home -p 8888:8888 finrl

Note: The default container run starts jupyter lab in the root directory, allowing you to run scripts, notebooks, etc.

Clone this repository:

git clone https://github.com/AI4Finance-LLC/FinRL-Library.git

Install the unstable development version of FinRL:

pip install git+https://github.com/AI4Finance-LLC/FinRL-Library.git

For OpenAI Baselines, you'll need system packages CMake, OpenMPI and zlib. Those can be installed as follows:

sudo apt-get update && sudo apt-get install cmake libopenmpi-dev python3-dev zlib1g-dev libgl1-mesa-glx

Installation of system packages on Mac requires Homebrew. With Homebrew installed, run the following:

brew install cmake openmpi

To install stable-baselines on Windows, please look at the documentation.

cd into this repository:

cd FinRL-Library

Under folder /FinRL-Library, create a Python virtual-environment:

pip install virtualenv

Virtualenvs are essentially folders that have copies of python executable and all python packages.

Virtualenvs can also avoid packages conflicts.

Create a virtualenv venv under folder /FinRL-Library

virtualenv -p python3 venv

To activate a virtualenv:

source venv/bin/activate

To activate a virtualenv on windows:

venv\Scripts\activate

The script has been tested running under Python >= 3.6.0, with the following packages installed:

pip install -r requirements.txt

Stable-Baselines3 is a set of improved implementations of reinforcement learning algorithms in PyTorch. It is the next major version of Stable Baselines. If you have questions regarding Stable-baselines package, please refer to Stable-baselines3 installation guide. Install the Stable Baselines package using pip:

pip install stable-baselines3[extra]

A migration guide from SB2 to SB3 can be found in the documentation.

Still Under Development

python main.py --mode=train

Use Quantopian's pyfolio package to do the backtesting.

The stock data we use is pulled from Yahoo Finance API.

(The following time line is used in the paper; users can update to new time windows.)

• FinRL is an open source library specifically designed and implemented for quant finance. Trading environments incorporating market frictions are used and provided.
• Trading tasks accompanied by hands-on tutorials with built-in DRL agents are available in a beginner-friendly and reproducible fashion using Jupyter notebook. Customization of trading time steps is feasible.
• FinRL has good scalability, with a broad range of fine-tuned state-of-the-art DRL algorithms. Adjusting the implementations to the rapid changing stock market is well supported.
• Typical use cases are selected and used to establish a benchmark for the quantitative finance community. Standard backtesting and evaluation metrics are also provided for easy and effective performance evaluation.

Will maintain FinRL with the "AI4Finance" community and welcome your contributions!

Thanks to all the people who contribute.

Support more markets, so that the users can test their stategies.

Maintain a pool of DRL algorithms that can be treated as SOTA implementations.

To help quants have better evaluations, will maintain benchmarks for many trading tasks, upon which you can improve for your own tasks.

Supporting live trading can close the simulation-reality gap, it will enable quants to switch to the real market when they are confident with their strategies.
