通达信『介入三部曲』精准捕捉回调/回踩/大底三大买入信号！
本套“介入三部曲”指标包含1个副图公式+4个公式，核心结合均线偏离度（6/12/24日均线）和类KDJ指标（K9/VARB/J9），量化股价超跌程度，划分“回调、回踩、大底”三个梯度介入信号：回调介入对应轻度超跌，回踩介入为中度超跌，大底介入是深度超跌，信号辨识度高，适配不同风险偏好的交易需求。
【使用方法】
1. 副图公式：导入通达信副图指标，图表中黄色柱=回调介入、蓝色柱=回踩介入、红色柱=大底介入，直观显示当日信号；
2. 公式：回调/回踩/大底介入可单独筛选对应级别标的，“回调回踩大底”筛选同时满足三类信号的标的（确定性更强）；
3. 实操建议：大底介入信号安全性最高，适合中长线布局；回踩介入适配波段操作；回调介入偏短线，建议结合量能、大盘环境综合决策 股朋网。
总结
1. 指标核心是通过均线偏离度+类KDJ指标判断超跌买入信号，分三个风险梯度；
2. 副图看信号、公式筛标的，使用场景清晰；
3. 不同信号适配不同交易风格，大底信号确定性最优。
