今天看到北沙老师在回复KD钝化指标时的指标,如下:RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;K:SMA(RSV,3,1);D:SMA(K,3,1);IF(COUNT(K>80 AND D>80,3)=3,95,DRAWNULL),POINTDOT,COLORGREEN,LINETHICK4;IF(COUNT(K<20 AND D<20,3)=3,5,DRAWNULL),POINTDOT,COLORFF33FF,LINETHICK4;如何将IF(COUNT(K<20 AND D<20,3)=3,5,DRAWNULL),POINTDOT,COLORFF33FF,LINETHICK4;此句写成选股公式? 编写条件：编写方法：every(.k<20 and j.d<20,3);&np;
