ITS-SentARL general architecture

Image source: Intelligent Trading Systems: A Sentiment-Aware Reinforcement Learning Approach article presented in the Second ACM International Conference on AI in Finance (ICAIF'21)

The stack bellow was used mostly due to its ease of installation, configuration, and also efficiency and portability.

• Language: Python (3.8.10)
• RL Environment: OpenAI gym (0.21.0)
• RL engine: StableBaselines3 (1.6.0)

This system was originally developed in Ubuntu 16.04 but will work properly on any other Operational System(OS X, Windows, etc.).

However, this guide will only include instructions for plugins and packages that are not already installed on this OS. For this reason, we assume that technologies like a python interpreter and pipenv are ready for use, and should not be on the scope of this document.

• Now install pipenv dependency manager:

$ pip install --user pipenv

Now we'll start setting up the project.

• Clone the repo from GitHub and change to project root directory. After that, install project dependencies and go to python virtual env, by running:

$ pipenv install
$ pipenv shell

The system will do the following:

1. Load financial data and prepare the trading environment. 2. Run a trading strategy and collect results. 3. Store all results regarding training, testing and validation in .csv files. 4. Optional: Save model versions at each training episode.

The base command to run in terminal is:

$ python app

There are three modes for running the project, which can be selected using the following arg

• mode with the allowed values: single for running a single configuration; routine for running several configurations; consolidation for grouping all results files into one single large file.

Then the arguments according to the desired modes are:

• stg for selecting the strategy to run. Allows: bh for Buy and Hold (BH); sentarl fpr the sentiment-aware RL algorithm; vanilla for the sentiment-free version of the algorithm.
• asset for selecting the asset to run trade. Allows: any asset present in the data/__init__.py file, with the corresponding .csv file in the data folder.
• algo for selecting the RL algorithm to run. Allows: a2c, ppo, dqn. To add more algorithms add code to the models\__init__.py and settings.py files, given it is implemented by StableBaselines3.
• episodes for selecting the number of episodes to train. Allows: integer values only
• setup for selecting the train/val window type of setup. Allows: static, rolling.

Example to run default mode with ITS-SentARL using A2C

python app mode=single setup=rolling stg=sentarl asset=aapl algo=A2C episodes=1 setup='rolling'

• routine_name for selecting which routine to run when mode arg is set to routine. Allows: default for running the most basic routine, load_model for running routines that load a model trained up to a given episode.

Example to run default routine

python app mode=routine routine_name=default

Beware this mode can take a long time to run depending on how many assets, tcs, rolling windows, stgs and other characteristics are selected.

Example to consolidate all results files

python app mode=consolidation
