SharpeArena for Python
The Python distribution combines the native SharpeArena engine with a Gymnasium-compatible environment and optional adapters for multi-agent, RLVR, offline-RL, MCP, and local-model workflows.
Point-in-time observations prevent future-bar access through the environment API. They do not isolate Python code from the host. Run trusted local code here, or use SharpeBench's digest-pinned container path for an untrusted entrant.
Install
pip install sharpearena
The base install includes NumPy, Gymnasium, the Python package, and the compiled pyo3 extension. Optional integrations are explicit:
pip install "sharpearena[pettingzoo]"
pip install "sharpearena[verifiers]"
pip install "sharpearena[minari]"
pip install "sharpearena[mcp]"
Step a Gymnasium environment
from sharpearena import SharpeArenaEnv
env = SharpeArenaEnv(n_symbols=4, n_days=120, seed=7)
observation, info = env.reset(seed=7)
terminated = truncated = False
while not (terminated or truncated):
action = env.action_space.sample()
observation, reward, terminated, truncated, info = env.step(action)
Actions are signed target-weight vectors in the environment's symbol order. The
default range is [-1, 1]; pass allow_short=False to make it [0, 1], or set
max_weight to change the per-symbol bound.
Importing sharpearena registers the following Gymnasium IDs:
SharpeArena/Calm-v1 SharpeArena/Calm-Eval-v1
SharpeArena/Hard-v1 SharpeArena/Hard-Eval-v1
SharpeArena/Extreme-v1 SharpeArena/Extreme-Eval-v1
The -Eval-v1 environments draw from the disjoint evaluation seed band. The -v1
suffix freezes the environment semantics; a rule change requires a new versioned ID.
Native boundary
sharpearena.sharpearena_py.TradingEnv is the low-level binding. Its boundary is
JSON: reset() returns an observation string, and step(decision_json) returns
(observation_json, reward, done, info_json). The Python Gymnasium wrapper converts
between that wire format and NumPy spaces.
The wheel ships py.typed and a stub for the compiled extension. Typed boundary
exceptions distinguish invalid input, invalid JSON, invalid salt, unavailable data,
and engine failures.
