买卖信号

- **周金叉**：周K线上穿周D线（周K>周D），看涨信号 - **周死叉**：周D线上穿周K线（周D>周K），看跌信号 - **日金叉（低金）**：日线K线上穿日线D线，且K值<20，FILTER过滤连续4周期，满足条件为"低金"信号 - **底背离**：K线与D线形成金叉时，股价创新低但KDJ未创新低，预示价格将反弹 - **顶背离**：D线与K线形成死叉时，股价创新高但KDJ未创新高，预示价格将回落

用法

1. **周线信号为主**：优先关注周金叉和周死叉，代表中长期趋势方向 2. **日线信号为辅**：在周线金叉前提下，日线出现"低金"（K<20的金叉）是较强的买入信号 3. **背离信号**：底背离是买入机会，顶背离是卖出机会，需结合成交量验证 4. **J线变色**：J线上升时显示洋红色（上涨趋势），下降时显示白色（调整或下跌） 5. **预判线**：K预判和D预判用于提前判断KDJ走向 6. **开口分析**：KD的开口大小反映多空力量对比
