Financial reinforcement learning (FinRL) (Document website) is the first open-source framework for financial reinforcement learning. FinRL has evolved into an ecosystem

Outline

Overview

FinRL has three layers: market environments, agents, and applications. For a trading task (on the top), an agent (in the middle) interacts with a market environment (at the bottom), making sequential decisions.

A quick start: Stock_NeurIPS2018.ipynb. Videos FinRL at AI4Finance Youtube Channel.

File Structure

The main folder finrl has three subfolders applications, agents, meta. We employ a train-test-trade pipeline with three files: train.py, test.py, and trade.py.
