"""mr_scanner.py — v_weak 弱市策略实盘扫描器（2026-08-05 从 v_mr 精选版切换）
|
||
|
||
v_weak 是六步法+12维框架定稿的弱市策略（docs/v_mr_strategy.md §19/§21），
|
||
全市场 10y 验证：234笔 / wr 62.4% / avg +7.17% / 8槽组合 ret 178.3% / cagr 12.8% / dd 16.4%。
|
||
v_mr 已被证伪（2018 依赖 + 去2018 掷硬币，§12），v_weak 是其替代。
|
||
|
||
入场条件（v_weak 六条件，与回测严格对齐）：
|
||
市场门控（main）：大盘 MA20 下方（trend_down/choppy）+ 大盘 ADX ∈ [25,30) 甜区
|
||
个股：
|
||
1. bias60 ∈ [-35, -20) : 深超跌但不过深（过深易续跌）
|
||
2. RSI14 ≤ 25 : 极度超卖
|
||
3. r5f ≤ -3% : 5日急跌（下跌动能确认）
|
||
4. dist_lo20 < 5% : 距20日低点 < 5%（下方有支撑承接，§17）
|
||
5. 信号日收阳 : 入场重评确认=资金进场（§19）
|
||
6. 缩量 vol5/vol20<1.0 : 入场重评确认=抛压衰竭（§19）
|
||
出场建议：tp=+30% / sl=-12% / max_hold=40 交易日（RR 2.5:1）
|
||
排序：bias60 升序（最深超跌优先，§15 自然序=隐式质量排序）
|
||
候选写入 sector='v_mr'（管道槽位名不变，下游兼容）
|
||
|
||
市场门控（2026-08-02 新增）：
|
||
- 只读 market_regime 表，regime 为 trend_down 或 choppy 时启用扫描
|
||
（v_mr 主战场：下跌趋势 + 震荡市；趋势市让位 v_next4）
|
||
- trend_up 时跳过（v_next4 追涨主战场，不扫超跌）
|
||
|
||
数据源：腾讯前复权日K（qfq），datalen=120（覆盖 MA60 + 60日回看 + RSI 收敛）
|
||
指标算法：与 backtest_framework.py 完全一致（内联，零偏差）
|
||
输出：candidates 表（sector='v_mr'），与 accumulation_scanner 同 UPSERT 模式
|
||
|
||
用法：
|
||
python3 mr_scanner.py # 完整扫描（regime 门控）
|
||
python3 mr_scanner.py --force # 忽略 regime 门控强制扫描
|
||
python3 mr_scanner.py --top N # 输出前 N 只（默认 10）
