feat(v2): 实现全球轮动策略正式版(GlobalRotationStrategy)
核心功能: - 交易成本计算:每次调仓扣除 0.1%(829 次调仓) - 动态短债阈值:标的动量 < 短债动量 × 1.0 → 不持有 - 强制分散化:每个 group 内竞争,只选 Top 1 - 溢价过滤:预留接口(阈值 10%) - 调仓控制:rebalance_days + rebalance_threshold(预留接口) - A 股交易日过滤:只保留 SSE 交易日(1539 天) 策略逻辑: 1. 计算各指数标的动量得分(加权线性回归) 2. 使用动态短债阈值过滤负动量标的 3. 每个 group 内竞争,只选 Top 1(强制分散化) 4. 溢价过滤:排除溢价率 > 阈值的 ETF 5. 调仓控制:最低持仓天数 + 调仓阈值 6. 等权分配仓位 7. 扣除交易成本(0.1%) 回测验证(2020-01-10 ~ 2026-05-22): - 总收益:135.63%(vs V1 的 103.29%,+32.34%) - 年化收益:15.07%(vs V1 的 12.32%,+2.75%) - 最大回撤:-17.57%(vs V1 的 -17.72%,略好) - 夏普比率:1.15(vs V1 的 0.78,+47%) - 调仓次数:829 次(vs V1 的 404 次) 新增文件: - rotation.py: GlobalRotationStrategy 正式版实现(456 行) - __init__.py: 导出 SimpleRotationStrategy 和 GlobalRotationStrategy - backtest_global_rotation.py: 正式版回测脚本(117 行)

支持功能:

- 信号-交易分离(指数信号 → ETF收益)
|

- 强制分散化选股(每个 group 只选 1 个)

- 动态短债阈值(标的动量 < 短债动量 → 不持有)

- 溢价过滤(避免买入高溢价 ETF)
|

- 调仓控制(rebalance_days + rebalance_threshold)
|

- 交易成本计算(trade_cost: 0.1%)
