该指标源码结合日线与周线KDJ指标，辅以EMA趋势分析，构建多维度交易信号体系。核心功能包括：1）计算日线KDJ（K、D值基于RSV的3日平滑移动平均），并叠加周线KDJ的5日均线（周K、周D、周J），通过双时间框架交叉（如周K与周D、日K与日D）用彩色柱状线提示多空信号；2）以周J值为基准，在J值回升但低于0时标记"关注区"，暗示超卖反弹机会；3）通过AA（蓝色）/BB（红色）曲线量化5日EMA趋势持续时间，结合红绿渐变带状区域直观展示多空趋势强度对比；4）动态显示周线J值的超买超卖状态（黄色线突显上行趋势）。整体通过颜色、柱状线、带状区等多重视觉元素，辅助判断中短期趋势转折点及买卖时机。
