## 💡 Usage Examples
### Portfolio Management
```python
from tradingagents.portfolio import Portfolio, MarketOrder
from decimal import Decimal
# Create portfolio with $100k
portfolio = Portfolio(
initial_capital=Decimal('100000.00'),
commission=Decimal('0.001') # 0.1% commission
)
# Buy 100 shares of AAPL at $150
order = MarketOrder('AAPL', Decimal('100'))
portfolio.execute_order(order, Decimal('150.00'))
# Check portfolio value
total_value = portfolio.total_value()
print(f"Portfolio Value: ${total_value:,.2f}")
# Get performance metrics
metrics = portfolio.get_performance_metrics()
print(f"Sharpe Ratio: {metrics.sharpe_ratio:.2f}")
print(f"Max Drawdown: {metrics.max_drawdown:.2%}")
print(f"Win Rate: {metrics.win_rate:.2%}")
# Get equity curve
equity_curve = portfolio.get_equity_curve()
# Save portfolio
portfolio.save('my_portfolio.json')
```
### Backtesting
```python
from tradingagents.backtest import Backtester, BacktestConfig
from tradingagents.backtest import BuyAndHoldStrategy
from decimal import Decimal
# Configure backtest
config = BacktestConfig(
initial_capital=Decimal('100000.00'),
start_date='2020-01-01',
end_date='2023-12-31',
commission=Decimal('0.001'),
slippage=Decimal('0.0005'),
benchmark='SPY',
)
# Create strategy
strategy = BuyAndHoldStrategy()
# Run backtest
backtester = Backtester(config)
results = backtester.run(
strategy=strategy,
tickers=['AAPL', 'MSFT', 'GOOGL']
)
# Print results
print(f"Total Return: {results.total_return:.2%}")
print(f"Sharpe Ratio: {results.sharpe_ratio:.2f}")
print(f"Max Drawdown: {results.max_drawdown:.2%}")
print(f"Win Rate: {results.win_rate:.2%}")
# Generate HTML report
results.generate_report('backtest_report.html')
# Compare to benchmark
comparison = results.compare_to_benchmark()
print(f"Alpha: {comparison['alpha']:.2%}")
print(f"Beta: {comparison['beta']:.2f}")
```
### Backtest TradingAgents
```python
from tradingagents.graph.trading_graph import TradingAgentsGraph
from tradingagents.backtest import backtest_trading_agents
# Create TradingAgents strategy
graph = TradingAgentsGraph(
selected_analysts=["market", "fundamentals", "news"],
config={"deep_think_llm": "gpt-4o-mini"}
)
# Run backtest (one line!)
results = backtest_trading_agents(
trading_graph=graph,
tickers=['AAPL', 'MSFT'],
start_date='2023-01-01',
end_date='2023-12-31',
initial_capital=100000.0,
)
# Analyze results
print(f"Total Return: {results.total_return:.2%}")
print(f"Sharpe Ratio: {results.sharpe_ratio:.2f}")
print(f"Number of Trades: {results.total_trades}")
# Generate report
results.generate_report('tradingagents_backtest.html')
```
### Custom Strategy
```python
from tradingagents.backtest import BaseStrategy, Signal
from decimal import Decimal
class MomentumStrategy(BaseStrategy):
"""Simple momentum strategy."""
def __init__(self, lookback=20):
super().__init__(name="Momentum")
self.lookback = lookback
def generate_signals(self, timestamp, data, positions, portfolio_value):
signals = []
for ticker, df in data.items():
if len(df) < self.lookback:
continue
# Calculate momentum
momentum = (df['close'].iloc[-1] / df['close'].iloc[-self.lookback]) - 1
# Buy if strong momentum and not holding
if momentum > 0.05 and ticker not in positions:
signals.append(Signal(
ticker=ticker,
timestamp=timestamp,
action='buy',
confidence=min(float(momentum) * 5, 1.0),
))
# Sell if negative momentum and holding
elif momentum < -0.02 and ticker in positions:
signals.append(Signal(
ticker=ticker,
timestamp=timestamp,
action='sell',
confidence=0.8,
))
return signals
# Use it
config = BacktestConfig(initial_capital=Decimal('100000'))
backtester = Backtester(config)
results = backtester.run(
MomentumStrategy(lookback=20),
tickers=['AAPL', 'MSFT', 'GOOGL']
)
```
