Quick Start

from ml4t.backtest import Engine, Strategy, BacktestConfig

class SimpleMovingAverage(Strategy):
    def __init__(self, fast=10, slow=30):
        self.fast = fast
        self.slow = slow
        
    def on_bar(self, bar):
        fast_ma = bar.close_ma(self.fast)
        slow_ma = bar.close_ma(self.slow)
        
        if fast_ma > slow_ma and self.position == 0:
            self.buy(size=100)
        elif fast_ma < slow_ma and self.position > 0:
            self.close()

config = BacktestConfig(
    initial_cash=100_000,
    commission=0.001,
)

engine = Engine(data, SimpleMovingAverage(), config)
result = engine.run()

print(f"Total Return: {result.total_return:.2%}")
print(f"Sharpe Ratio: {result.metrics['sharpe']:.2f}")
