买卖信号

1. **低位金叉**：DIFF上穿DEA，且DIFF<-0.1，表示短期有望反弹的买入信号 2. **二次金叉**：DIFF上穿DEA且DEA<0，21日内出现第2次金叉，是较强的买入信号 3. **底背离**：价格创新低但MACD未创新低后金叉，是底部的买入信号 4. **顶背离**：价格创新高但MACD未创新高后死叉，是顶部的卖出信号

用法

这是一个MACD指标的优化版本，主要用于判断趋势和背离。适用于中长线趋势判断，在震荡行情中需结合其他指标。注意事项：1）低位金叉和二次金叉是主要买入信号，建议在零轴下方出现时关注；2）底背离是较为可靠的买入信号，顶背离是卖出信号；3）MACD柱状图的颜色变化反映多空力量对比；4）可配合成交量和其他指标综合判断。
