规则：空仓时 H=过去 10 日最高价，首次盘中最低价跌破 H×0.98 锁定 H； H×0.98~0.93 每档买入，目标金额 = max(1 万, 1 手价格)，按首笔价确定； 最新价只用于分组，两者可能不同；卖出从最深档开始， 目标价 H×(档位+2%)；全部卖光一轮结束；下一轮需间隔 20 个交易日且收盘创上一轮 H 新高。
解套天数：只统计“至少买到第二档（-3%）且已经卖光”的轮次——只买第一档、 没被套就卖的不算解套，单独看“单票统计”。未平仓单列“未平最长”， 不参与最短/中位/平均/最长，避免把刚开的单子误算成长期套牢。
未平仓：期末仍持有的轮次，按 2026-11-05 收盘价计浮盈亏；不强行平仓。
数据：2018-01-02 ~ 2026-11-05，后复权日线；停牌/一字板不成交；收益按后复权比例折算；仅供研究。
