网友求助：
请老师帮忙下把下公式改成预警
A1:=C-REF(C,1);
A2:=100*EMA(EMA(A1,10),10)/EMA(EMA(ABS(A1),10),10);
买进:(LLV(A2,5)=LLV(A2,10) AND COUNT(A2<0,5) AND crOSS(A2,MA(A2,5))),colorred;
DRAWTEXT(买进,0.5,'↖买进'),coloryellow;
A1:=C-REF(C,1);
A2:=100*EMA(EMA(A1,10),10)/EMA(EMA(ABS(A1),10),10);
买进:(LLV(A2,5)=LLV(A2,10) AND COUNT(A2<0,5) AND crOSS(A2,MA(A2,5))),colorred;
DRAWTEXT(买进,0.5,'↖买进'),coloryellow;
解答如下：
A1:=C-REF(C,1);
A2:=100*EMA(EMA(A1,10),10)/EMA(EMA(ABS(A1),10),10);
买进:(LLV(A2,5)=LLV(A2,10) AND COUNT(A2<0,5) AND CROSS(A2,MA(A2,5)));
A2:=100*EMA(EMA(A1,10),10)/EMA(EMA(ABS(A1),10),10);
买进:(LLV(A2,5)=LLV(A2,10) AND COUNT(A2<0,5) AND CROSS(A2,MA(A2,5)));
