买卖信号
**买入信号（底背离）**： 1. MACD底背：B1条件满足（MACD金叉且股价创新高），显示红色点 2. KDJ底背：B2条件满足（KDJ金叉且股价创新高），显示洋红色点 3. RSI底背：B3条件满足（RSI金叉且股价创新高），显示黄色点 **卖出信号（顶背离）**： 1. MACD顶背：D1条件满足（MACD死叉且股价创新低），显示绿色点 2. KDJ顶背：D2条件满足（KDJ死叉且股价创新低），显示橙色点 3. RSI顶背：D3条件满足（RSI死叉且股价创新低），显示白色点
用法
1. **适用场景**：适用于判断股价的底背离和顶背离，辅助判断趋势反转点 2. **使用方法**： - 当出现底背离信号（MACD/KDJ/RSI底背）时，考虑买入建仓 - 当出现顶背离信号（MACD/KDJ/RSI顶背）时，考虑卖出清仓 - 可结合DIF、DEA的交叉信号以及MACD柱状图颜色变化进行综合判断 3. **注意事项**： - 底背离：股价创新低但指标未创新低，是潜在买入信号 - 顶背离：股价创新高但指标未创新高，是潜在卖出信号 - 建议多种指标背离共振时信号更可靠 - 该指标为辅助判断工具，需结合其他分析方法综合决策
