通达信EMACD指标（MACD类）指标公式
买卖信号
1. **金叉/死叉信号**： - JC：DIFF上穿DEA（金叉） - SC：DEA上穿DIFF（死叉） - JC2：DIFF第二次上穿DEA（二次金叉） - SC2：DEA第二次上穿DIFF（二次死叉） 2. **多头信号（'多'）**：N2=1且N1在5-13之间，且DIFF>0且DEA>0持续N1天，并满足JC条件，显示红色"多"字 3. **空头信号（'空'）**：M2=1且M1在5-13之间，且DIFF<0且DEA<0持续N2天，并满足SC条件，显示绿色"空"字 4. **风险信号**：在二次金叉/死叉后，若在4天内出现死叉/金叉，显示"风险"提示 5. **顶背离信号**：B8>80时B18下穿B8，且前一波高点比前前一波高点低，显示"顶背离" 6. **底背离信号**：B8<25时B8上穿B18，且前一波低点比前前一波低点高，显示"底背离" 7. **画线**：通过DRAWLINE绘制背离相关的连接线（红色为多头背离线，绿色为空头背离线）
用法
1. **适用场景**：用于判断MACD背离情况，识别潜在的趋势转折点 2. **主要功能**： - 多头市场（DIFF>0且DEA>0）中出现金叉时显示"多"信号 - 空头市场（DIFF<0且DEA<0）中出现死叉时显示"空"信号 - 识别MACD顶背离和底背离 - 通过B8/B18指标辅助判断超买超卖状态 3. **注意事项**： - "多"和"空"信号要求DIFF和DEA同向运行一段时间后再出现交叉 - 风险信号提示可能的双顶/双底形态 - 需结合股价走势综合判断背离信号的有效性 - 背离信号仅供参考，需结合其他分析方法
