nexusquant-sdk

NexusQuant strategy provider Python SDK.

Installation

pip install nexusquant-sdk

Quick start

import nexusquant_sdk as nq

# Authenticate once (opens browser)
nq.auth_login()

# List your strategies
strategies = nq.strategy_list()

# Send a signal
nq.strategy_send_signal_single(
    "my_alpha",
    ticker="AAPL",
    direction="buy",
    price=150.0,
    quantity=100,
    order_type="LIMIT",
)

Authentication

Tokens are stored locally at the path returned by nq.auth_credentials_path().

nq.auth_login()           # opens Cognito Hosted UI, saves tokens
nq.auth_logged_in()       # True if a token is present
nq.auth_refresh()         # force-refresh the ID token via refresh token
nq.auth_logout()          # delete local tokens
nq.auth_credentials_path() # path to the credentials file

Override defaults with environment variables:

Strategy API

# Register / update a strategy
nq.strategy_register("my_alpha", "My Alpha Strategy", output_unit="SHARE_COUNT")

# List strategies
nq.strategy_list()

# Signal history
nq.strategy_signal_history("my_alpha", limit=20)

# Send a single signal
nq.strategy_send_signal_single(
    "my_alpha",
    ticker="AAPL",
    direction="buy",   # "buy" or "sell"
    price=150.0,
    quantity=100,      # share count
    order_type="LIMIT" # "MARKET" or "LIMIT"
)

# Send a multi-route signals map
nq.strategy_send_signals("my_alpha", {"default": {...}})
nq.strategy_send_signals_from_path("my_alpha", "signals.json")

# Subscriber configuration snapshot
nq.strategy_subscriber_config("my_alpha")
