This folder has three subfolders:

• applications: trading tasks,
• agents: DRL algorithms, from ElegantRL, RLlib, or Stable Baselines 3 (SB3). Users can plug in any DRL lib and play.
• meta: market environments, we merge the stable ones from the active FinRL-Meta repo.

Then, we employ a train-test-trade pipeline by three files: train.py, test.py, and trade.py.
