openoutcry (Python)

Python distribution of OpenOutcry — a leak-free, point-in-time Gym for trading agents. A pyo3 binding over the Rust environment plus a gymnasium-compatible wrapper and a PrimeIntellect verifiers environment.

from openoutcry import OpenOutcryEnv

env = OpenOutcryEnv(n_symbols=4, n_days=120, seed=7)
obs, info = env.reset()
done = False
while not done:
    action = env.action_space.sample()      # target-weight vector
    obs, reward, terminated, truncated, info = env.step(action)
    done = terminated or truncated

The native binding (openoutcry.openoutcry_py.TradingEnv) exchanges the language-agnostic wire JSON at its boundary: reset() -> str and step(decision_json) -> (obs_json, reward, done, info_json).
