指标是一个综合性的技术分析工具，主要用于识别价格走势中的关键节点和趋势状态。
主要功能：
1. 识别近期高低点：自动标记并绘制最近N周期内的最高价和最低价水平线，并标注数值。
2. 绘制K线变色与特殊形态：
根据一系列复杂的连续价格关系判断，将上涨和下跌的K线分别用红色和橙色实体进行染色。
特别标识出由跌转涨的“黄托底”和由涨转跌的“蓝压顶”关键反转K线。
3. 绘制支撑与阻力线：通过`PEAK`和`TROUGH`函数，绘制基于前期高点的绿色阻力线（FG）和基于前期低点的红色支撑线（FD）。
使用要点：
指标直接在K线主图上叠加显示，包含水平线、彩色K线和文字标注。
“近期高点”和“近期低点”的水平线有助于观察当前价格的相对位置和潜在的支撑阻力。
彩色K线及“托底”、“压顶”信号旨在帮助判断短期多空力量的转换点。
绿线（FG）和红线（FD）构成了一个动态的通道或波段参考，用于判断趋势的延续或突破。
