    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'))

        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)
