💡 Usage Examples

Basic Trading

from tradingagents.brokers import AlpacaBroker
from tradingagents.brokers.base import BrokerOrder, OrderSide, OrderType
from decimal import Decimal

# Connect to paper trading
broker = AlpacaBroker(paper_trading=True)
broker.connect()

# Check account
account = broker.get_account()
print(f"Buying Power: ${account.buying_power}")

# Buy 10 shares of AAPL
order = BrokerOrder(
    symbol="AAPL",
    side=OrderSide.BUY,
    quantity=Decimal("10"),
    order_type=OrderType.MARKET
)

executed = broker.submit_order(order)
print(f"Order ID: {executed.order_id}")

# Check positions
positions = broker.get_positions()
for pos in positions:
    print(f"{pos.symbol}: {pos.quantity} shares, P&L: ${pos.unrealized_pnl}")

TradingAgents Integration

from tradingagents.graph.trading_graph import TradingAgentsGraph
from tradingagents.brokers import AlpacaBroker

# Initialize TradingAgents
ta = TradingAgentsGraph()

# Connect to broker
broker = AlpacaBroker(paper_trading=True)
broker.connect()

# Analyze stock
final_state, signal = ta.propagate("NVDA", "2024-05-10")

# Execute signal
if signal == "BUY":
    order = broker.buy_market("NVDA", Decimal("5"))
    print(f"Bought NVDA: {order.order_id}")
elif signal == "SELL":
    position = broker.get_position("NVDA")
    if position:
        order = broker.sell_market("NVDA", position.quantity)
        print(f"Sold NVDA: {order.order_id}")

    quantity=Decimal("5"),
    limit_price=Decimal("250.00")
)

# Stop Loss (sell if price drops)
from tradingagents.brokers.base import BrokerOrder, OrderSide, OrderType

🏗️ Architecture

BaseBroker Interface

All broker implementations inherit from BaseBroker and provide:

Account Management:

  • get_account() - Account info and buying power
  • get_positions() - All current positions
  • get_position(symbol) - Specific position

Order Management:

  • submit_order(order) - Place an order
  • cancel_order(order_id) - Cancel pending order
  • get_order(order_id) - Check order status
  • get_orders(status, limit) - List orders

Market Data:

  • get_current_price(symbol) - Latest price

Convenience Methods:

  • buy_market(symbol, quantity) - Quick market buy
  • sell_market(symbol, quantity) - Quick market sell
  • buy_limit(symbol, quantity, price) - Quick limit buy
  • sell_limit(symbol, quantity, price) - Quick limit sell

Data Models

BrokerOrder:

@dataclass
class BrokerOrder:
    symbol: str
    side: OrderSide  # BUY or SELL
    quantity: Decimal
    order_type: OrderType  # MARKET, LIMIT, STOP, STOP_LIMIT
    limit_price: Optional[Decimal] = None
    stop_price: Optional[Decimal] = None
    time_in_force: str = "day"  # day, gtc, ioc, fok
    order_id: Optional[str] = None
    status: OrderStatus = OrderStatus.PENDING

BrokerPosition:

@dataclass
class BrokerPosition:
    symbol: str
    quantity: Decimal
    avg_entry_price: Decimal
    current_price: Decimal
    market_value: Decimal
    unrealized_pnl: Decimal
    unrealized_pnl_percent: Decimal
    cost_basis: Decimal

BrokerAccount:

@dataclass
class BrokerAccount:
    account_number: str
    cash: Decimal
    buying_power: Decimal
    portfolio_value: Decimal
    equity: Decimal
    currency: str = "USD"
    pattern_day_trader: bool = False

🔒 Security Best Practices

  1. Never commit API keys - Use .env file (already in .gitignore)
  2. Use paper trading first - Test thoroughly before live trading
  3. Set position limits - Protect against runaway algorithms
  4. Monitor continuously - Check logs and positions regularly
  5. Start small - Begin with minimal capital

🐛 Troubleshooting

Connection Errors

Problem: ConnectionError: Invalid API credentials

Solution:

  1. Check API keys are correct in .env
  2. Ensure no extra spaces in keys
  3. Verify you're using paper trading keys for paper mode
  4. Regenerate keys if needed

Order Failures

Problem: InsufficientFundsError

Solution:

  1. Check buying power: account.buying_power
  2. Paper accounts start with $100,000 (default)
  3. Reduce order quantity

Problem: OrderError: Order rejected

Solution:

  1. Check market is open (9:30 AM - 4:00 PM ET, weekdays)
  2. Verify ticker symbol is valid
  3. Check order parameters (price, quantity)

Market Hours

Stock markets are closed:

  • Weekends
  • US holidays
  • Before 9:30 AM ET
  • After 4:00 PM ET

Use time_in_force="gtc" (good-til-canceled) for orders outside hours.

📊 Complete Example

See examples/tradingagents_with_alpaca.py for a full integration example showing:

  1. TradingAgents analysis
  2. Signal generation
  3. Order execution
  4. Position tracking
  5. Performance monitoring

🎓 Next Steps

  1. Learn the API: Run examples/paper_trading_alpaca.py
  2. Test Strategies: Use paper trading to validate
  3. Monitor Performance: Track P&L and metrics
  4. Refine Approach: Iterate based on results
  5. Go Live: When confident, switch to live trading

📚 Resources

⚠️ Disclaimer

Trading involves risk. Paper trading results do not guarantee live trading success. Always:

  • Start with small positions
  • Use stop losses
  • Diversify holdings
  • Never invest more than you can afford to lose
  • Understand the risks before trading
