一、指标定位
“反包确立鱼身”是一套通达信指标组合，聚焦短线攻击动能与趋势拐点的共振，由副图公式和条件公式两部分组成。
二、核心图理
副图以EMA(2)价格线相对42日斜率平台“网”的位置来区分多空：价格在“网”上方时显示洋红柱，在下方时显示蓝柱，便于快速判断中期强弱。
核心信号是“大笔”（改良RSV动能线）上穿“趋势”（RSV动能线）形成金叉，代表股价由弱转强的启动拐点；若再满足10日前股价已站上60日均线这一多头过滤条件，则触发“反包”信号，意味着主力反手做多，行情有望进入“鱼身”主升段。
三、副图信息
1. 人气温度计：按换手率分档画柱，青柱＜3%为清冷，黄柱3%-7%为活跃，红柱≥7%为热烈，并提供阶段平均成本参考。
2. 多方/主力线：两线背离时加粗显示。大笔上行、趋势下行标注“多方”，视为潜在吸筹；反向则标注“主力”，视为潜在派发。
3. 拐头与确认：在筹码获利盘基础上，叠加量比放大与120日低位条件，分别显示“拐头”“确认”；动量MM从超买区回落时，触发“预警”。
4. 反包信号：J值上穿倒序值且均线多头时，亮起彩色柱群；大笔上穿趋势处标注“信号确定”，可视为短线买点。
四、筛选用法
公式：XG:CROSS(大笔,趋势)。可用于盘后批量初筛出现动能金叉的个股。实战中建议再叠加均线多头、温和放量及大盘环境进行人工复核，以规避缩量弱势中的假信号。
五、风险提示
指标只是辅助工具，仍需结合基本面和市场情绪判断。操作上应严格止损，切忌盲目追高。
