Stock Trading Market OpenAI Gym Environment with Deep Reinforcement Learning using Keras

Overview

This project provides a general environment for stock market trading simulation using OpenAI Gym. Training data is a close price of each day, which is downloaded from Google Finance, but you can apply any data if you want. Also, it contains simple Deep Q-learning and Policy Gradient from Karpathy's post.

In fact, the purpose of this project is not only providing a best RL solution for stock trading, but also building a general open environment for further research.
So, please, manipulate the model architecture and features to get your own better solution.

Requirements

• Python2.7 or higher
• Numpy
• HDF5
• Keras with Beckend (Theano or/and Tensorflow)
• OpenAI Gym

Usage

Note that the most sample training data in this repo is Korean stock. You may need to re-download your own training data to fit your purpose.

After meet those requirements in above, you can begin the training both algorithms, Deep Q-learning and Policy Gradient.

Train Deep Q-learning:

$ python market_dqn.py  [model filename]

Train Policy Gradient:

$ python market_pg.py  [model filename]

For example, you can do like this:

$ python market_pg.py ./kospi_10.csv pg.h5

Aware that the provided neural network architecture in this repo is too small to learn. So, it may under-fitting if you try to learn every stock data. It just fitted for 10 to 100 stock data for a few years. (I checked!!)
Thus you need to re-design your own architecture and
let me know if you have better one!

Below is training curve for Top-10 KOSPI stock datas for 4 years using Policy Gradient.

To do

• Test environment to check overfitting.
• Elaborate the PG's train interface.
