『顶底双识别』副图+指标 捕捉买卖点！玩转股票高低位精准判断
公式介绍
顶底双识别是一套适配通达信的实用指标体系，包含副图与公式，核心围绕斐波那契分割线（0.191/0.382/0.5/0.618/0.809）结合CCI、EMA等经典指标，精准识别股票顶底区间、支撑压力位。副图公式直观展示高区（红色）、低区（绿色）、各关键支撑压力线，还通过不同颜色K线标注超买超卖信号；公式则聚焦趋势线低位拐头向上的见底信号，筛选出具备底部反转潜力的个股。
使用方法
1. 副图公式：导入通达信副图指标后，可自定义参数K（统计周期）、N（显示周期），重点关注“支撑-0.191”“压力-0.809”区间，K线触及低区+第一/二防线是低吸参考，触及高区+压力线是止盈参考；
2. 公式：直接导入条件公式，执行可筛选出“趋势线≤13且拐头向上”的见底个股，结合副图指标的低区信号使用，提升胜率。
总结
1. 该指标核心是斐波那契分割线结合趋势、量能指标，实现顶底区间可视化；
2. 副图看区间、抓见底，二者结合可精准把握股票高低位买卖时机；
3. 自定义K/N参数可适配不同周期（日线/周线）的分析需求。
