求老师改成选股预警公式
选股条件：（买进=1)
A7:=C-REF(C,1);
A8:=100*EMA(EMA(A7,6),6)/EMA(EMA(ABS(A7),6),6);
买进:(LLV(A8,2)=LLV(A8,7) AND COUNT(A8<0,2) AND CROSS(A8,MA(A8,2))),COLORRED;
DRAWTEXT(买进,0.5,'↖买进'),COLORYELLOW;

DRAWTEXT(买进,0.5,'↖买进'),COLORYELLOW;
解答如下：
A7:=C-REF(C,1);
A8:=100*EMA(EMA(A7,6),6)/EMA(EMA(ABS(A7),6),6);
买进:(LLV(A8,2)=LLV(A8,7) AND COUNT(A8<0,2) AND CROSS(A8,MA(A8,2)));
A8:=100*EMA(EMA(A7,6),6)/EMA(EMA(ABS(A7),6),6);
买进:(LLV(A8,2)=LLV(A8,7) AND COUNT(A8<0,2) AND CROSS(A8,MA(A8,2)));
