一、故事引入：从“追涨杀跌”到“通道信徒”的蜕变
二、核心内容（康奈尔笔记体）
1. 指标设计思路：三步解码股价运行密码
HHV/LLV函数抓取10日内的阶段高低点，锁定股价波动箱体（源码第7-15行）。DRAWLINE函数连接历史高点形成上轨（压力位），历史低点形成下轨（支撑位），中轨=（上轨+下轨）/2（源码第21-45行）。
2. 三大原理拆解
CC:=FILTER(QY,HIGHN) AND H=HHV(H,HIGHN+1)（第9行），筛选10日内创新高且未被打破的强势形态。CC1:=FILTER(QY1,LOWN) AND L=LLV(L,LOWN+1)（第33行），捕捉10日超跌后的筹码低吸机会。
3. 实战案例+记忆口诀
