这是一款专为波段操作设计的股票指标公式，融合了KDJ、威廉指标、RSI及斐波那契加权等多种技术分析逻辑，适合用于主图和买卖点判断。
核心逻辑：
公式通过36周期多重平滑RSI（JXZB系列）捕捉极端位置，当JXZB3上穿JXZB4且数值低于20时，触发"抄底"信号并标注绿色柱体；当JXZB4上穿JXZB3且数值高于80时，触发"逃顶"信号并标注黄色柱体。同时叠加KDJ金叉死叉图标（ICO4/ICO5）和L2/L3红绿趋势柱，形成多重验证。
使用方法：
将源码导入文华财经主图后，重点关注三个信号：①"抄底"文字+绿色柱出现时为买入参考；②"逃顶"文字+黄色柱出现时为卖出参考；③KDJ图标辅助确认短期转折。参考线80/50/20可辅助判断强弱区间。
适用场景： 适合中短线波段操作者，尤其在震荡市中，该抄底逃顶指标的多重过滤机制能有效减少假信号，比单一KDJ或RSI公式更稳定。
