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;
