通达信MACD买卖背离小牛指标（MACD类）指标公式

买卖信号

1. **低位金叉**：DIFF与DEA在低位（DIFF<-0.1）形成金叉，黄色柱状线显示 2. **二次金叉**：DEA<0区域，21天内出现第二次金叉，紫色柱状线+图标显示 3. **底背离**：价格创新低但DIFF未创新低，随后金叉，红色柱状线+画线显示 4. **顶背离**：价格创新高但DIFF未创新高，随后死叉，绿色画线显示 5. **买1信号**：LSMR条件（操作线上穿13日高点且股价收阳），且非重复信号

用法

1. **适用场景**：适用于中短线交易，辅助判断MACD金叉/死叉信号 2. **买入时机**：低位金叉、二次金叉、底背离金叉出现时可考虑买入 3. **卖出时机**：顶背离死叉出现时考虑卖出 4. **注意事项**： - 二次金叉信号相对可靠性较高 - 背离信号需要结合成交量验证 - 买1信号需要满足股价站在13日高点之上的条件 - 该指标为MACD改良指标，需结合其他分析方法综合判断
