写下这个macd主图的选股公式

macd主图公式：
DIF:IF(EMA(C,12)>EMA(C,26),EMA(C,12),EMA(C,26));
DEA:IF(EMA(EMA(C,12),9)>EMA(EMA(C,26),9),EMA(EMA(C,12),9),EMA(EMA(C,26),9));
请老师帮忙编写：在金叉的状态下，DIF和DEA的角度大于N的选股 ，谢谢先了。

 

DIF:IF(EMA(C,12)>EMA(C,26),EMA(C,12),EMA(C,26));
DEA:IF(EMA(EMA(C,12),9)>EMA(EMA(C,26),9),EMA(EMA(C,12),9),EMA(EMA(C,26),9));
jiaodua:=ATAN((DIF/REF(DIF,1)-1)*100)*57.3;
jincha:=cross(DIF,DEA);
jincha and jiaodua>=n;
