(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 | Full lock definitions: [references/LOCKS.md](references/LOCKS.md) ## 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 All 25 anti-patterns: [references/ANTI_PATTERNS.md](references/ANTI_PATTERNS.md) ## Evidence Quality Notice > [QUALITY NOTICE] This crystal was compiled from blueprint finance-bp-120.
