通达信MACD金箍棒指标（MACD类）指标公式

买卖信号

1. **低位金叉**：DIFF与DEA在DIFF<-0.1时形成金叉，显示"低位金叉"文字提示 2. **二次金叉**：DIFF与DEA在DEA<0时形成金叉，且为21日内第二次金叉，显示"二次金叉"文字和图标提示 3. **底背离**：股价创新低但DIFF未创新低，且DIFF与DEA形成金叉，显示"底背离"文字提示 4. **顶背离**：股价创新高但DIFF未创新高，且DEA与DIFF形成死叉，画出绿色下降趋势线

用法

本指标为MACD指标的优化版本，主要用于判断趋势反转和买卖时机。**低位金叉**和**二次金叉**为买入信号，**底背离**是较强的买入信号，**顶背离**为卖出信号。使用时需注意：1）需结合股价整体趋势判断，避免在震荡市中频繁使用；2）二次金叉信号可信度高于一次金叉；3）背离信号需结合成交量验证；4）建议配合其他指标（如均线、成交量）综合决策。
