通达信MACD起涨指标（趋势型）指标公式

买卖信号

1. **BUYDIFF再上（蓝色）**：DIFF短期调整后再上涨，即REF(DIFF,3)<REF(DIFF,2) AND REF(DIFF,1)<REF(DIFF,2) AND REF(DIFF,1)<DIFF 2. **BUYDIF上拐（红色）**：DIFF线上拐，且不是BUYDIFF再上信号，即REF(DIFF,1)<REF(DIFF,2) AND REF(DIFF,1)<DIFF 3. **BUYMACD上拐（洋红色）**：MACD柱状线向上拐头，即REF(MACD,1)<REF(MACD,2) AND REF(MACD,1)<MACD AND REF(DIFF,1)<REF(DIFF,2) 4. **SELLMACD下拐（绿色）**：MACD柱状线向下拐头，即REF(MACD,1)>REF(MACD,2) AND REF(MACD,1)>MACD

用法

该指标是基于MACD系统的趋势跟踪指标，主要用于判断MACD各组成部分的拐点信号。使用时需注意：（1）参数设置为12、27、9的标准MACD参数；（2）DIFF上拐和MACD上拐信号用于判断买入时机；（3）MACD下拐信号用于判断卖出或观望时机；（4）可结合成交量放量条件（放量起涨:V>REF(V,1)*1.618）增强信号可靠性；（5）该指标侧重于捕捉趋势转换的拐点，适合趋势行情中的买卖点把握。
