A 股量化实验室 (a-stock-quant-lab)

说出"跟机构持仓"或"MACD 回测"——我基于 zvt 直接写代码跑起来，不用你翻文档。 美股数据质量一般，不推荐。

Pipeline

data_collection -> data_storage -> factor_computation -> target_selection -> trading_execution -> visualization

Top Use Cases (31 total)

Actor Data Recorder (UC-101)

Collects institutional investor holdings and top 10 free float shareholders on a weekly schedule for tracking major player positions Triggers: institutional investor, top holders, actor data

Financial Statement Recorder (UC-102)

Collects fundamental financial data including balance sheets, income statements, and cash flow statements from eastmoney on a weekly basis Triggers: financial statements, balance sheet, income statement

Index Data Recorder (UC-103)

Collects index metadata, index compositions (SZ1000, SZ2000, growth, value indices), and daily index price data Triggers: index data, index composition, SZ1000

For all 31 use cases, see references/USE_CASES.md.

Execute trigger: When user intent matches intent_router.uc_entries[].positive_terms AND user uses action verb (run/execute/跑/执行/backtest/fetch/collect)

What I'll Ask You

• Target market: A-share (default), HK, or crypto? (US stocks in ZVT are half-baked — stockus_nasdaq_AAPL exists but coverage is thin)
• Data source / provider: eastmoney (free, no account), joinquant (account+paid), baostock (free, good history), akshare, or qmt (broker)?
• Strategy type: MACD golden-cross, MA crossover, volume breakout, fundamental screen, or custom factor?
• Time range: start_timestamp and end_timestamp for backtest period
• Target entity IDs: specific stocks (stock_sh_600000) or index components (SZ1000)?

Semantic Locks (Fatal)

ID	Rule	On Violation
SL-01	Execute sell orders before buy orders in every trading cycle	halt
SL-02	Trading signals MUST use next-bar execution (no look-ahead)	halt
SL-03	Entity IDs MUST follow format entity_type_exchange_code	halt
SL-04	DataFrame index MUST be MultiIndex (entity_id, timestamp)	halt
SL-05	TradingSignal MUST have EXACTLY ONE of: position_pct, order_money, order_amount	halt
SL-06	filter_result column semantics: True=BUY, False=SELL, None/NaN=NO ACTION	halt
SL-07	Transformer MUST run BEFORE Accumulator in factor pipeline	halt
SL-08	MACD parameters locked: fast=12, slow=26, signal=9	halt

Top Anti-Patterns (47 total)

• AP-ZVT-183: 除权因子为 inf/NaN 时直接参与乘法导致复权静默失败
• AP-ZVT-179: 第三方数据接口超限后异常被吞噬，数据静默缺失
• AP-ZVT-200: Token 失效后数据查询返回空 DataFrame 而非报错
