Usage

Selecting a broker

client.execution.use_broker("alpaca", env="paper")

Submit / cancel / replace order (sync)

from cpz.execution.models import OrderSubmitRequest, OrderReplaceRequest
from cpz.execution.enums import OrderSide, OrderType, TimeInForce

req = OrderSubmitRequest(symbol="AAPL", side=OrderSide.BUY, qty=1,
                         type=OrderType.MARKET, time_in_force=TimeInForce.DAY)
order = client.execution.submit_order(req)
client.execution.cancel_order(order.id)
client.execution.replace_order(order.id, OrderReplaceRequest(qty=2))

Async + Streaming

import asyncio
from cpz.clients.async_ import AsyncCPZClient

async def main():
    client = AsyncCPZClient()
    await client.execution.use_broker("alpaca", env="paper")
    async for q in client.execution.stream_quotes(["AAPL", "MSFT"]):
        print(q.symbol, q.bid, q.ask)
        break

asyncio.run(main())

Get account / positions

acct = client.execution.get_account()
positions = client.execution.get_positions()

CPZ AI - Strategies & Files

Access your CPZ AI platform data including strategies and files:

from cpz.common.cpz_ai import CPZAIClient

# Connect to CPZ AI
client = CPZAIClient.from_env()

# Get your strategies (user-specific by default)
strategies = client.get_strategies()
print(f"Your strategies: {[s.get('title', 'Unknown') for s in strategies]}")

# Create a new strategy (automatically assigned to your user_id)
new_strategy = client.create_strategy({
    "title": "My Trading Bot",
    "description": "Automated trading strategy",
    "strategy_type": "momentum",
    "status": "active"
})

User-Specific Access Control

The CPZ AI client automatically handles user isolation:

• Regular Users: Only see and manage their own strategies and files
• Admins: Can access all strategies and files across all users

# Regular user client (user-specific access)
user_client = CPZAIClient(
    url="https://api.cpz-lab.com",
    api_key="your_api_key",
    secret_key="your_secret_key",
    user_id="user123",
    is_admin=False
)

# Admin client (full access)
admin_client = CPZAIClient(
    url="https://api.cpz-lab.com",
    api_key="admin_api_key",
    secret_key="admin_secret_key",
    user_id=None,
    is_admin=True
)

# Environment variables for automatic configuration
# CPZ_AI_USER_ID=user123
# CPZ_AI_IS_ADMIN=false

File Operations & DataFrames

Upload, download, and manage files with pandas DataFrame support:

import pandas as pd

# Create a sample DataFrame
df = pd.DataFrame({
    'symbol': ['AAPL', 'GOOGL', 'MSFT'],
    'price': [150.25, 2750.80, 310.45],
    'volume': [1000000, 500000, 800000]
})

# Upload DataFrame as CSV
client.upload_dataframe("data-bucket", "stocks.csv", df, format="csv")

# Upload DataFrame as JSON
client.upload_dataframe("data-bucket", "stocks.json", df, format="json")

# Upload DataFrame as Parquet
client.upload_dataframe("data-bucket", "stocks.parquet", df, format="parquet")

# Download CSV and load to DataFrame
downloaded_df = client.download_csv_to_dataframe("data-bucket", "stocks.csv")

# Download JSON and load to DataFrame
downloaded_df = client.download_json_to_dataframe("data-bucket", "stocks.json")

# Download Parquet and load to DataFrame
downloaded_df = client.download_parquet_to_dataframe("data-bucket", "stocks.parquet")

# List files in a bucket
files = client.list_files_in_bucket("data-bucket", prefix="stocks")

# Delete files
client.delete_file("data-bucket", "stocks.csv")

Load User Strategies to DataFrame

from cpz.common.cpz_ai import CPZAIClient
import pandas as pd

# Load strategies for a specific user
client = CPZAIClient(
    url="https://api.cpz-lab.com",
    api_key="your_api_key",
    secret_key="your_secret_key",
    user_id="user-uuid-here",
    is_admin=False
)

# Get user's strategies as DataFrame
strategies_df = pd.DataFrame(client.get_strategies())
print(f"Found {len(strategies_df)} strategies")
print(strategies_df.head())

Note: The CPZ AI client connects to your API endpoint at api.cpz-lab.com. Users only need to provide their CPZ AI API keys.

CLI

cpz-ai broker list
cpz-ai broker use alpaca --env paper
cpz-ai order submit --symbol AAPL --side buy --qty 10 --type market --tif day
cpz-ai order get --id <id>
