RSV:=(CLOSE-LLV(L,9))/(HHV(H,9)-LLV(L,9))*100;
K:=SMA(RSV,3,1);{KDJ的K值}
D:=SMA(K,3,1);{KDJ的D值}
J:=3*K-2*D;{KDJ的J值}
BIAS1:=(C-MA(C,50))/MA(C,50)*100;{50日均线乖离率}
A1:=COUNT(J<0,15)>=2;{最近15个周期有2个周期的J值小于0}
A2:=CROSS(K,D) AND K<50 AND C>REF(C,1);{K、D金叉，金叉时K小于50，当天是上涨}
A3:=BIAS1<-15;{50日均线乖离率小于-15}
A4:=NOT(NAMEINCLUDE('ST'));{名称中不包含ST}
XG:A1 AND A2 AND A3 AND A4;{A1、A2、A3、A4四个条件同时成立};
