海龟策略是一种趋势跟踪策略,使用Python编写可以参考以下步骤:
1. 导入必要的库:
```python
import pandas as pd
import numpy as np
import talib as ta
import yfinance as yf
```
2. 获取股票数据:
```python
data = yf.download("AAPL", start="2020-01-01", end="2021-01-01")
```
3. 计算海龟策略的入市价格、止损价格、退出价格:
```python
data['20d_high'] = ta.MAX(data['High'], timeperiod=20)
data['10d_low'] = ta.MIN(data['Low'], timeperiod=10)
data['long_entry'] = data['20d_high']
data['long_stop'] = data['10d_low']
data['long_target'] = data['Close'] + (data['20d_high'] - data['10d_low']) * 2
```
4. 定义海龟策略的交易信号:
```python
data['signal'] = 0
data.loc[data['Close'] > data['long_entry'], 'signal'] = 1
data.loc[data['Close'] < data['long_stop'], 'signal'] = -1
```
5. 计算海龟策略的收益率:
```python
data['pct_change'] = data['Close'].pct_change()
data['strategy_returns'] = data['pct_change'] * data['signal'].shift(1)
data['cum_returns'] = (1 + data['strategy_returns']).cumprod()
```
这样就可以得到海龟策略的收益曲线并进行分析和优化了。当然,这只是一个简单的示例,实际应用中需要根据具体的情况进行调整和优化。
