股票形态筛选 (stock-pattern-screener)
使用7种技术形态检测器（杯柄、三周紧绑、高紧旗、VCP、NR7等）按确定性顺序扫描股票池，支持跨检测器评分校准与置信度聚合排序。

Top Use Cases (30 total)
FastAPI Application Bootstrap (UC-001)
Provides the main FastAPI application entry point with CORS middleware, dependency injection wiring, and runtime service initialization for the Hermes Triggers: api, server, start
Server Authentication Service (UC-005)
Provides single-user server authentication helpers including token encoding, decoding, expiration checking, and HMAC signature validation for securing Triggers: auth, authentication, token
Setup Engine Pattern Detection (UC-014)
Detects chart patterns (VCP, Cup-with-Handle, NR7, etc.) using normalized scoring and cross-detector calibration for trade setup quality assessment Triggers: setup, pattern, vcp
For all 30 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 |
