使用方式

1. 因子计算

from scripts.alpha101 import compute_alphas, alpha101

# 输入: date x ticker DataFrame
data = {
    'open': df_open, 'close': df_close, 'high': df_high, 'low': df_low,
    'volume': df_vol, 'vwap': df_vwap, 'returns': df_returns
}

# 计算所有可用因子
alphas = compute_alphas(data)  # dict of alpha_name -> DataFrame

# 单独计算
from scripts.alpha101 import alpha101
a101 = alpha101(df_open, df_close, df_high, df_low)

2. 因子IC测试

python scripts/compute_ic.py --data <path> --output results/

3. 单因子回测

python scripts/backtest_alpha.py --alpha 101 --data <path>

因子分类

类别因子输入
纯价量#1-#47, #49-#55, #60, #61, #71-#74, #84, #88, #101OHLCV + VWAP
行业中性化#48, #56, #58-#59, #63, #67, #69-#70, #76, #79-#82, #87, #89-#91, #93, #97, #100+ 行业分类
复杂参数#57-#99非整数窗口, 混合权重

基础函数速查

rank(x)              截面排名 [0,1]
delay(x,d)           d天前的值
delta(x,d)           当期 - d天前
correlation(x,y,d)   d天滚动相关
scale(x,a=1)         缩放使sum(abs(x))=a
decay_linear(x,d)    线性衰减加权均值
ts_min/ts_max(x,d)   滚动最小/最大
ts_rank(x,d)         时间序列排名
ts_sum/ts_std(x,d)   滚动求和/标准差
adv{d}               d天平均成交额
IndNeutralize(x,ind) 行业中性化

回测注意事项

  1. 交易成本: 论文因子扣除cost后Sharpe才是真Sharpe
  2. 过拟合: 101个因子中部分可能已衰减,需样本外验证
  3. 市场适配:
    • A股: T+1限制,持仓期需调整
    • 加密: 24/7,日频→小时频需改窗口参数
    • Polymarket: 流动性低,部分因子不适用
  4. 行业因子: 需要行业分类映射,加密市场可用板块替代

决策框架

因子计算 → IC/IR筛选(>0.03) → 样本外验证 → 组合构建(低相关等权) → 回测扣费 → 实盘
