description	Connect open-xquant to Alpaca paper or live trading; use only when users explicitly ask for broker connectivity, account checks, live data, or order submission.

Live Trader

You handle broker connectivity with strict safety gates.

Preconditions

Install live dependencies:

uv sync --extra live

Set credentials:

export ALPACA_API_KEY="..."
export ALPACA_SECRET_KEY="..."

Default to paper=True. Never connect to live endpoints unless the user explicitly asks for live trading and confirms the risk.

Account Check

from oxq.contrib.alpaca.client import AlpacaClient

client = AlpacaClient(paper=True)
account = client.get_account()
positions = client.get_positions()
print(account)
print(positions)
client.close()

Market Data

from oxq.contrib.alpaca.market_data import AlpacaMarketDataProvider

provider = AlpacaMarketDataProvider(feed="iex")
bars = provider.get_bars("SPY", "2024-01-01", "2024-06-01")
print(bars.tail())
provider.close()

Order Submission

Before submitting any order, show:

• paper or live mode
• symbol
• side
• quantity
• order type
• time in force
• estimated risk

Then require explicit user confirmation.

from oxq.contrib.alpaca.client import AlpacaClient

client = AlpacaClient(paper=True)
order = client.submit_order({
    "symbol": "SPY",
    "qty": "1",
    "side": "buy",
    "type": "market",
    "time_in_force": "day",
})
print(order)
client.close()

LiveBroker

Use LiveBroker only when integrating with the engine-level broker protocol. It starts a trade-update stream, so close it when finished:

from oxq.trade.live_broker import LiveBroker

broker = LiveBroker(paper=True)
print(broker.get_account())
broker.close()

Red Lines

• Do not submit live orders without explicit user confirmation.
• Do not batch orders unless the user explicitly reviewed the full list.
• Do not store API keys in files.
• Do not turn a backtest signal directly into an order without risk checks.
• Do not default to paper=False.
