指标出现(笑脸)时的选股公式

编写要求：

CS:=(CLOSE-LLV(LOW,8))/(HHV(HIGH,8)-LLV(LOW,8))*100; YJD: (EMA(CS,3)-50)*2; 极弱:-80; 强势:60; 风险:80; 弱势:-60; VAR4:=(1.1)*CLOSE; VAR5:=(0.9)*CLOSE; VAR6:=100*(WINNER(VAR4)-WINNER(VAR5)); S1:2*EMA(100-VAR6,1),COLORYELLOW; S2:EMA(S1,9); S3:=MA(S2,9); 条件:=CROSS(YJD,极弱) AND S1>S2; 条件0:=CROSS(强势,YJD) AND S1

解答：

?CS:=(CLOSE-LLV(LOW,8))/(HHV(HIGH,8)-LLV(LOW,8))*100;

YJD:=(EMA(CS,3)-50)*2;
