A股量化分析

基于 akshare（免费无需token）的A股量化分析工具包。

快速开始

pip install akshare pandas numpy matplotlib

工作流

1. 获取数据

from scripts.fetch_data import *
ETF日线
df = fetch_etf_daily("159915", "20250101", "20260301")
个股日线
df = fetch_stock_daily("000001", "20250101", "20260301")
ETF分时（日内做T）
df = fetch_etf_intraday("159915")
实时行情
df = fetch_realtime("159915")

详见 references/api-reference.md

2. 计算技术指标

from scripts.technical_indicators import *
单指标
df['macd'], df['signal'], df['hist'] = calc_macd(df['close'])
df['k'], df['d'], df['j'] = calc_kdj(df['high'], df['low'], df['close'])
df['rsi'] = calc_rsi(df['close'], period=14)
df['upper'], df['mid'], df['lower'] = calc_bollinger(df['close'])
df['vol_ratio'] = calc_volume_ratio(df['volume'])
一键全部
df = add_all_indicators(df)
信号检测
signals = detect_signals(df)

3. 策略回测

from scripts.backtest import *
result = run_backtest(
    df,
    strategy="grid",           # grid / ma_cross / bollinger
    initial_capital=100000,
    grid_num=10,               # 网格数（grid策略）
    ma_short=5, ma_long=20,    # 均线参数（ma_cross策略）
    stop_loss=0.05,            # 止损比例
    take_profit=0.10,          # 止盈比例
)
print(result.summary())

4. 风险评估

from scripts.backtest import assess_risk
risk = assess_risk(df['close'])
returns: max_drawdown, sharpe_ratio, annual_volatility, calmar_ratio

策略库

ETF日内做T策略详解见 references/strategies.md，包含：

| 策略 | 适用场景 | 核心逻辑 | |------|---------|---------| | 网格交易 | 震荡市 | 价格跌破网格线买入，涨回卖出 | | 均线交叉 | 趋势市 | 短均线上穿长均线买入，下穿卖出 | | 布林带回归 | 均值回归 | 触下轨买入，触上轨卖出 | | 波动率突破 | 突破行情 | ATR放大+价格突破时追入 |

风控参数（内置默认值）

RISK_PARAMS = {
    "max_position_pct": 0.25,    # 单只持仓上限
    "stop_loss": 0.05,           # 止损线 5%
    "take_profit": 0.10,         # 止盈线 10%
    "max_daily_turnover": 0.05,  # 日内做T最大换手
    "min_trade_amount": 10000,   # 最低交易金额（元）
    "max_drawdown_limit": 0.15,  # 最大回撤警戒线
}
