FinRL_Podracer is an intermediate-level, cloud-native framework for financial reinforcement learning, targeting full-stack developers and quantitative traders. It simplifies the development of algorithmic trading strategies by providing a lightweight, efficient, and stable library built on PyTorch and ElegantRL, enabling fast code iteration and performance comparable to Ray RLlib.

How It Works

The framework models stock trading as a Markov Decision Process (MDP), aiming to maximize expected returns. It utilizes an OpenAI gym-style environment for interaction, with states represented by a 181-dimensional vector including balance, stock prices, shares, and technical indicators like MACD, RSI, CCI, and ADX. Actions involve buying, selling, or holding stocks, with a configurable action space. The library supports a wide range of model-free DRL algorithms for both continuous and discrete action spaces.

Quick Start & Requirements

• Install via pip install elegantrl.
• Requires Python 3.x.
• Demo notebook StockTrading_Demo.ipynb available for a PPO-based trading strategy.
• Official documentation and educational resources are available via links in the project's repository.

Highlighted Details

• Supports DDPG, TD3, SAC, A2C, PPO (with GAE) for continuous actions.
• Supports DQN, DoubleDQN, D3QN for discrete actions.
• Includes MILP for portfolio optimization using natural evolutionary strategies.
• Core code is under 800 lines, emphasizing a Pythonic and lean development approach.
• State-of-the-art DRL algorithms are implemented with a focus on researcher control and performance.
