## 模块
|
||||
|
||||
- `alpha_factors` — 158 alpha 公式 + 24 基础算子(移植自 qlib alpha158)
|
||||
- `execution` — 执行仿真(成本/滑点/T+1/涨跌停/部分成交/价差)+ 多日 NAV + PnL 拆解(借鉴 hikyuu 部件化思想)
|
||||
- `execution` — A 股长仓执行仿真(成本/滑点/现金约束)+ 稀疏调仓/完整交易日 Ledger + 可投影成交与 NAV 审计;T+1、涨跌停、成交量与价差提供独立约束函数
|
||||
- `indicators` — 50+ 技术指标(MACD / KDJ / 布林 / ATR / ADX / 等)
|
||||
- `data_adapter` — 桥接 qtdb_pro 长表与新模块(rename / long-wide / 复权 / vwap 代理)
|
||||
- `backtest` — weight-based 多日仿真(rebalance_table / compute_nav / compare_to_benchmark)
|
||||
- `metrics` — 绩效(年化收益 / 波动率 / Sharpe / 最大回撤 / Calmar)
|
||||
- `portfolio_construction` — 多期因子分数 → Top-K → 等权目标权重表
|
||||
- `research_pipeline` — 因子日 → 下一真实交易日 → 显式执行价 → 日末估值 → 成本后绩效(防前视编排)
|
||||
- `artifact` — 版本化、确定性、存储中立的完整 research run 事实表与 manifest
|
||||
- `attribution` — 基于实际成交后持仓的隔夜 / 日内 / 交易成本逐日收益归因与闭合审计
|
||||
- `metrics` — 绝对绩效 + 严格日期对齐的 TE / IR / alpha / beta 基准相对绩效
|
||||
- `factor_library` — 通用方法(turnover / winsorize / IC / OLS / jb_test)
|
||||
- `portfolio_decomp` — 组合分解(risk_parity / mean_variance / 因子归因)
|
||||
- `risk` — 风险指标(边际 / 风险贡献)
|
||||
- `risk` — ndarray 低层风险公式 + 标签安全、可分组的 Euler 成分风险分解
|
||||
- `perf_stats` — 详细绩效(与 metrics 并存)
|
||||
- `logging` — 统一 logger(标准库 + 可选 loguru)
