指标是一个综合性的技术分析工具，主要包含趋势判断和买卖点提示功能。
核心功能与使用说明：
1. 三重平滑趋势线：通过计算收盘价与最低价的均值，并进行三次指数移动平均，得到三条平滑线（O1、O2、O3）。它们用于判断短期价格趋势，其排列和交叉可反映动能变化。
2. 20日均线参考与标记：计算20日简单移动平均线（MMM）。当收盘价高于此均线时，在均线位置用蓝色“”标记；低于时用绿色“”标记，直观显示价格相对于中期均线的位置。
3. 复杂形态识别与提示：
“买进”信号：通过一系列复杂的条件组合（VAR1至VAR19），识别出潜在的底部反转或启动形态。当条件满足时，在K线低点附近显示“买进”文字及图标。
“逃顶”信号：通过另一组条件组合（VARD至VAR1A），识别出潜在的顶部反转或下跌启动形态。当条件满足时，在K线高点附近显示“逃顶”文字。
4. 顶部预警柱：当识别出“逃顶”条件（VAR1A）时，在对应的前一根K线位置绘制一组由宽到窄、颜色渐变的柱状线，起到视觉警示作用。
使用要点：
指标通过多重条件过滤，旨在捕捉价格在连续窄幅波动后的突破启动点（买进）或趋势衰竭反转点（逃顶）。使用者应结合“买进”/“逃顶”文字提示、图标以及彩色预警柱进行综合判断。三条趋势线的方向与相互关系可作为趋势强弱的辅助参考。
