不选出ST类股

这个公式选出了很多ST股，请教怎样才能不选出ST类股，谢谢！！！！！ VAR1:=3; VAR2:=(3)*(SMA(((CLOSE - LLV(LOW,27))/(HHV(HIGH,27) - LLV(LOW,27)))*(100),5,1)) - (2)*(SMA(SMA(((CLOSE - LLV(LOW,27))/(HHV(HIGH,27) - LLV(LOW,27)))*(100),5,1),3,1)); 准备启爆点:IF(CROSS(VAR2,VAR1),100,0);

爱约股解答：

AA:=IF(NAMELIKE('S'),0,1) AND IF(NAMELIKE('*'),0,1);{去除ST}

BB:=DYNAINFO(17)>0;{去除停牌}

VAR1:=3;

VAR2:=(3)*(SMA(((CLOSE - LLV(LOW,27))/(HHV(HIGH,27) - LLV(LOW,27)))*(100),5,1)) - (2)*(SMA(SMA(((CLOSE - LLV(LOW,27))/(HHV(HIGH,27) - LLV(LOW,27)))*(100),5,1),3,1));

准备启爆点:=IF(CROSS(VAR2,VAR1),100,0);

XG:AA AND BB AND 准备启爆点;
