通达信MACD加强版指标（MACD类）指标公式

买卖信号

1. **低位金叉**：DIFF与DEA在低位形成金叉（DIFF<-0.1），表示买入信号 2. **二次金叉**：DIFF与DEA在零轴以下形成第二次金叉（21日内第二次金叉），是较强的买入信号 3. **底背离**：股价创新低但MACD未创新低，随后出现金叉，是买入信号 4. **顶背离**：股价创新高但MACD未创新高，随后出现死叉，是卖出信号（仅画线，无文字提示）

用法

该指标是基于MACD的改良指标，包含以下用法： - **适用场景**：中短线交易，用于判断趋势转折点和背离信号 - **买入时机**：低位金叉、二次金叉、底背离出现时 - **卖出时机**：顶背离出现时（DEA下穿DIFF） - **注意事项**： - 二次金叉信号比普通金叉更可靠 - 底背离是重要的趋势反转信号 - 需结合成交量和其他指标综合判断 - MACD在震荡行情中可能出现频繁金叉死叉，需过滤假信号
