把这个MACD底背离指标改成飞狐的

编写要求：

这个是通达信用的麻烦老师修改成飞狐用的，谢谢啦 DIFF:=EMA(CLOSE,12)-EMA(CLOSE,27); DEA:=EMA(DIFF,9); A1:=BARSLAST(REF(CROSS(DIFF,DEA),1)); 底背离:=REF(CLOSE,A1+1)>CLOSE AND DIFF>REF(DIFF,A1+1) AND CROSS(DIFF,DEA); DEA1:=EMA(EMA(CLOSE,12)/EMA(CLOSE,27),9); 角度:ATAN(DEA1/REF(DEA1,A1+1)*100-100)*57.3,NODRAW; 底背离; 最好在做个选股公式

解答：

?DIFF:=EMA(CLOSE,12)-EMA(CLOSE,27);

DEA:=EMA(DIFF,9);
