This main folder is organized into three subfolders:

• apps: tens of trading tasks,
• drl_agents: tens of DRL algorithms, from ElegantRL, RLlib, or Stable Baselines 3 (SB3). Users can plug in any DRL lib and play.
• finrl_meta: hundreds of market environments, we marge the stable ones from the active FinRL-Meta repo.

Then, we employ a train-test-trade pipeline, via three files:

• train.py,
• test.py
• trade.py.
