通达信MACD精确背离指标（MACD类）指标公式

买卖信号

**买入信号：** 1. 金叉（DIFF上穿DEA且DEA≤0） 2. 低位多次金叉（DIFF上穿DEA且满足多次条件且DEA≤0） 3. 底背离（价格创新低但DIFF未创新低，形成背离） **卖出信号：** 1. 死叉（DEA上穿DIFF且DEA≥0） 2. 高位多次死叉（DEA上穿DIFF且满足多次条件且DEA≥0） 3. 顶背离（价格创新高但DIFF未创新高，形成背离） **其他信号：** - DRAWLINE绘制底背离红色支撑线（COLORRED） - DRAWLINE绘制顶背离绿色压力线（COLOR00FF00） - STICKLINE绘制MACD红绿柱状图

用法

1. **适用场景**：适用于中长线趋势判断，配合MACD标准金叉死叉使用 2. **核心逻辑**： - DIFF与DEA的金叉死叉作为基本买卖点 - 底背离/顶背离作为趋势反转的预警信号 - "低位多次金叉"和"高位多次死叉"是增强信号，需满足连续条件 3. **注意事项**： - 背离信号需结合成交量验证 - 多次金叉/死叉条件较为严格，可减少假信号 - 需结合其他指标或均线系统综合判断 - 适用于趋势明确的行情，震荡市中需谨慎使用
