您好,使用Python编写期货的双均线策略是一个常见的量化交易策略。下面是一个简单的示例,展示如何使用Python实现基于双均线策略的期货交易逻辑。这个例子将使用`pandas`库处理数据以及`backtrader`库来构建交易策略。
安装必要的库
首先确保安装了`pandas`和`backtrader`库:
```bash
pip install pandas backtrader
```
创建策略类
接着,创建一个简单的双均线策略类,该类继承自`bt.Strategy`:
```python
import backtrader as bt
class DoubleMovingAverage(bt.Strategy):
params = (
('fast_period', 10), # 快速移动平均线的周期
('slow_period', 30), # 慢速移动平均线的周期
('printlog', False),
)
def log(self, txt, dt=None):
''' Logging function for this strategy '''
if self.params.printlog:
dt = dt or self.datas[0].datetime.date(0)
print(f'{dt.isoformat()}, {txt}')
def __init__(self):
# Keep a reference to the "close" line in the data[0] dataseries
self.data_close = self.datas[0].close
# To keep track of pending orders and buy price/commission
self.order = None
self.buyprice = None
self.buycomm = None
# Add a MovingAverageSimple indicator
self.fast_sma = bt.indicators.SimpleMovingAverage(
self.datas[0], period=self.params.fast_period)
self.slow_sma = bt.indicators.SimpleMovingAverage(
self.datas[0], period=self.params.slow_period)
# CrossOver of the two moving averages
self.crossover = bt.indicators.CrossOver(self.fast_sma, self.slow_sma)
def next(self):
if not self.position:
if self.crossover > 0:
self.log(f'BUY CREATE, {self.data_close[0]}')
self.buy()
else:
if self.crossover < 0:
self.log(f'SELL CREATE, {self.data_close[0]}')
self.sell()
def notify_order(self, order):
if order.status in [order.Submitted, order.Accepted]:
return
if order.status in [order.Completed]:
if order.isbuy():
self.log(f'BUY EXECUTED, Price: {order.executed.price}, Cost: {order.executed.value}, Commission: {order.executed.comm}')
self.buyprice = order.executed.price
self.buycomm = order.executed.comm
else:
self.log(f'SELL EXECUTED, Price: {order.executed.price}, Cost: {order.executed.value}, Commission: {order.executed.comm}')
elif order.status in [order.Canceled, order.Margin, order.Rejected]:
self.log('Order Canceled/Margin/Rejected')
self.order = None
def notify_trade(self, trade):
if not trade.isclosed:
return
self.log(f'OPERATION PROFIT, GROSS {trade.pnl:.2f}, NET {trade.pnlcomm:.2f}')
```
### 运行策略
最后,我们需要加载历史数据并运行策略:
```python
if __name__ == '__main__':
cerebro = bt.Cerebro()
# 加载数据
data = bt.feeds.YahooFinanceData(dataname='^VIX', fromdate=datetime(2023, 1, 1), todate=datetime(2024, 8, 1))
cerebro.adddata(data)
# 添加策略
cerebro.addstrategy(DoubleMovingAverage)
# 设置初始资金
cerebro.broker.setcash(100000.0)
# 打印起始资金
print('Starting Portfolio Value: %.2f' % cerebro.broker.getvalue())
# 运行策略
cerebro.run()
# 打印结束资金
print('Final Portfolio Value: %.2f' % cerebro.broker.getvalue())
```
以上代码展示了如何使用`backtrader`库来实现一个简单的双均线策略。请注意,这里的示例使用了虚拟数据`^VIX`作为示例,您需要替换为您感兴趣的期货合约的历史数据文件。此外,根据您的具体需求,您可能还需要调整参数或添加更多功能。
