买卖信号
1. **二次金叉**：DIF与DEA在零轴下方形成二次金叉（DEA<0且21日内出现2次金叉），显示图标和"二次金叉"文字提示 2. **底背离**：股价创新低但DIF未创新低，形成底背离，显示"底背离"文字和向上图标 3. **顶背离**：股价创新高但DIF未创新高，形成顶背离，显示"顶背离"文字和向下图标 4. **MACD&KDJ共振**：DIF上穿DEA同时K上穿D且J上穿D，显示"MACD&KDJ共振"文字和图标
用法
该指标为MACD与KDJ组合指标，适用于中短期交易分析。使用时注意：①二次金叉为较明确的买入信号，尤其在零轴下方时可靠性较高；②底背离出现在下跌趋势中可能预示反弹，頂背离出现在上涨趋势中可能预示回调；③MACD&KDJ共振信号为多方共振，表明市场短期强势，可作为积极买入参考；④指标含有多空信号但无明确卖出条件提示，需结合其他分析方法判断卖点；⑤建议配合成交量和均线系统综合判断，以提高信号可靠性。
