将“牛熊三色”指标做个预警

请老师帮忙将MACD翻红、sar翻红、ema翻红同时满足做个预警，谢谢 DIF:=EMA(C,12)-EMA(C,26); DEA:=EMA(DIF,9); MACD:=(DIF-DEA)*2,COLORSTICK; MACD翻红:CROSS(DIF,DEA); SAR翻红:CROSS(C,SAR(10,2,20)); EMA翻红:CROSS(EXPMA(C,7),EXPMA(C,21));

爱约股解答：

DIF:=EMA(C,12)-EMA(C,26);

DEA:=EMA(DIF,9);

MACD:=(DIF-DEA)*2,COLORSTICK;

CROSS(DIF,DEA) AND CROSS(C,SAR(10,2,20)) AND CROSS(EXPMA(C,7),EXPMA(C,21));
