Top Use Cases (8 total)
Moving Average Factor Computation (UC-101)
Computes and stores a 5-day moving average (MA5) factor for daily stock data, enabling technical indicator analysis across multiple stocks using Click Triggers: factor, moving average, MA5
Factor Tear Sheet Analysis (UC-102)
Retrieves pre-computed MA5 factor data from ClickHouse and generates comprehensive tear sheets for factor performance analysis and visualization in re Triggers: tear sheet, factor analysis, visualization
Zero-Copy Data Bridge Conversion (UC-103)
Demonstrates efficient zero-copy conversion between Pandas and Polars dataframes, and shared memory-based cross-process data transmission for high-per Triggers: pandas, polars, conversion
For all 8 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 (25 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-183B: HFQ（后复权）与 QFQ（前复权）K 线表使用错误导致因子计算漂移
