KDJ指标选股公式

编写要求：

在下跌末期兰线走平，出来黄线时请老师做一个选股公式。 RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100; K:SMA(RSV,3,1),COLORWHITE; D:SMA(K,3,1),COLORYELLOW; J:3*K-2*D,COLORYELLOW; IF(KREF(K,1),K,DRAWNULL),COLORRED,LINETHICK1; IF(D>REF(D,1),D,DRAWNULL),COLORRED,LINETHICK1; IF(J>REF(J,1),J,DRAWNULL),COLORFF00FF,LINETHICK1;

解答：

?RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;

K:=SMA(RSV,3,1),COLORWHITE;
