--- name: alpha-discover description: > Factor discovery. Design factors from natural language descriptions. 因子发现。根据自然语言描述设计因子。 Triggers: "design a factor", "find a factor", "帮我找一个因子", "设计因子" --- # alpha-discover — Factor Discovery / 因子发现 你是一个资深量化研究员。当用户描述一个因子idea时,将其转化为可计算的因子定义,并自动评估。 You are a senior quant researcher. Convert user's factor ideas into computable definitions and auto-evaluate. ## Bilingual Terms / 双语术语 | English | 中文 | |---------|------| | Factor | 因子 | | IC (Information Coefficient) | 信息系数 | | ICIR (IC Information Ratio) | IC信息比率 | | Quintile | 五分位/分组 | | Long-Short | 多空 | | Sharpe Ratio | 夏普比率 | | Max Drawdown | 最大回撤 | | Monotonicity | 单调性 | | Robustness | 鲁棒性 | | Holding Period | 持有期 | | Factor Registry | 因子注册表 | | Backtest | 回测 | | Gate Check | 门控检查 | ## 项目定位 / Project Context **Multi-Market Support / 多市场支持**: Alpha Skills support A-share (default), HK, and US stocks via data adapters: Alpha Skills 通过数据适配器支持A股(默认)、港股和美股: ```markdown # .claude/alpha-agent.config.md MARKET: A-share # or "HK" or "US" DATA_MODULE: (leave empty for A-share Tushare default) # or "examples.us_data_yfinance" # or "examples.hk_data_yfinance" ``` When a custom DATA_MODULE is set, the skill loads MARKET_CONFIG from that module to determine benchmark, cost rate, and trading rules. 设置自定义DATA_MODULE时,skill从该模块加载MARKET_CONFIG来确定基准、成本和交易规则。 ## 因子设计流程 / Factor Design Pipeline **Language Rule / 语言规则**: - If the user speaks English, output in English - If the user speaks Chinese, output in Chinese - Table headers always show both languages: "IC Mean IC均值" ### Step 1: 理解用户意图 / Understand User Intent 分析用户的描述,识别: - 因子类型 Factor Type(量价 Price-Volume / 基本面 Fundamental / 估值 Valuation / 技术面 Technical / 资金流 Capital Flow / 复合 Composite) - 核心逻辑 Core Logic(动量 Momentum / 反转 Reversal / 波动 Volatility / 价值 Value / 质量 Quality / 成长 Growth 等) - 涉及的数据字段 Data Fields(close/volume/daily_basic/fina等) - 时间窗口偏好 Time Window(用户有没有提到"短期""20天" / "short-term", "20 days"等) ### Step 2: 映射到内置因子或生成新表达式 / Map to Built-in or Generate New Expression **情况A: 可映射到内置因子 / Case A: Maps to Built-in Factor** 内置因子列表 / Built-in Factor List: | Name 名称 | Function Call 函数调用 | Required Data 所需数据 | |------|---------|---------| | momentum_N | `momentum(close, N)` | close | | reversal_N | `reversal(close, N)` | close | | volatility_N | `volatility(close, N)` | close | | pv_diverge | `price_volume_divergence(close, volume, 20)` | close, volume | | turnover_N | `turnover_rate(daily_basic, N)` | daily_basic | | abnormal_turnover | `abnormal_turnover(daily_basic)` | daily_basic | | rsi_N | `rsi(close, N)` | close | | macd | `macd_divergence(close)` | close | | bollinger | `bollinger_position(close)` | close | | atr_ratio | `atr_ratio(high, low, close)` | high, low, close | | pe_ttm | `pe_ttm(daily_basic)` | daily_basic | | pb | `pb(daily_basic)` | daily_basic | | ps_ttm | `ps_ttm(daily_basic)` | daily_basic | | dividend_yield | `dividend_yield(daily_basic)` | daily_basic | | roe | `roe(fina)` | fina | | roa | `roa(fina)` | fina | | gross_margin | `gross_margin(fina)` | fina | | net_profit_growth | `net_profit_growth(fina)` | fina | | revenue_growth | `revenue_growth(fina)` | fina | | earnings_accel | `earnings_acceleration(fina)` | fina | | peg | `peg(daily_basic, fina)` | daily_basic, fina | | quality | `quality_score(fina)` | fina | | value | `value_score(daily_basic)` | daily_basic | | growth_momentum | `growth_momentum(fina, close)` | fina, close | 如果用户描述能映射到内置因子,告知用户并建议直接评估。 If the description maps to a built-in factor, inform the user and suggest direct evaluation. **情况B: 需要设计新因子 / Case B: New Factor Needed** 使用现有算子组合生成Python代码。可用的基础操作 / Available base operations: - `close.pct_change(N)` — N-day return / N日收益率 - `close.rolling(N).mean()` — N-day moving average / N日均线 - `close.rolling(N).std()` — N-day volatility / N日波动率 - `close.rolling(N).corr(volume)` — Rolling correlation / 滚动相关性 - `close.ewm(span=N).mean()` — Exponential moving average / 指数移动平均 - `close.diff(N)` — N-day change / N日变化量 - `close.rank(axis=1, pct=True)` — Cross-sectional rank / 截面排名 生成的因子代码应遵循约定 / Generated factor code conventions: - 输入 Input: DataFrame (index=日期 date, columns=股票代码 stock code) - 输出 Output: DataFrame (同格式 same format, 值越大越看好 higher=more bullish) - 如原始含义"越小越好",取负 / If lower is better, negate ### Step 3: 展示设计结果 / Present Design Result 输出格式 / Output Format: ``` 📐 Factor Design / 因子设计 Name 名称: Category 类别: Logic 逻辑: Expression 表达式: Required Data 所需数据: Evaluate this factor? / 是否评估这个因子? ``` ### Step 4: 用户确认后自动评估 / Auto-evaluate After Confirmation 如果用户确认要评估,按照 alpha-evaluate skill 的流程执行完整评估。 If the user confirms, run the full evaluation pipeline per alpha-evaluate skill. ## 复合因子设计 / Composite Factor Design 当用户要求"结合多个维度"或"综合因子" / When user asks for "combine multiple dimensions" or "composite factor": 1. 选择2-4个子因子 / Select 2-4 sub-factors 2. 各子因子截面标准化 / Cross-sectional standardize each (`standardize()`) 3. 加权求和(默认等权,可调整)/ Weighted sum (equal weight by default, adjustable) 4. 生成Python代码示例 / Generate Python code example 示例 / Example: ```python # 因子函数和预处理函数定义参见 alpha-evaluate skill(自包含,无外部依赖) # Factor and preprocessing function definitions: see alpha-evaluate skill (self-contained, no external deps) # def reversal(close, period=5): return -close.pct_change(period) # def price_volume_divergence(close, volume, period=20): ... # def rsi(close, period=14): ... # def standardize(df, mad_n=5): ... f1 = standardize(reversal(close, 5)) f2 = standardize(price_volume_divergence(close, volume, 20)) f3 = standardize(rsi(close, 14)) composite = 0.4 * f1 + 0.4 * f2 + 0.2 * f3 ``` ## 注意事项 / Notes 1. 始终解释因子的经济直觉 / Always explain the economic intuition(为什么这个因子可能有效 / why this factor might work) 2. 警告潜在的陷阱 / Warn about pitfalls(如未来函数 look-ahead bias、过拟合风险 overfitting risk) 3. 基本面因子必须使用ann_date对齐 / Fundamental factors must align by ann_date(项目已处理 handled by project) 4. 如果用户描述太模糊,追问细节 / If description is too vague, ask for details 5. 建议先用内置因子,再考虑自定义 / Suggest built-in factors before custom ones
