KDJ编写选股（预警）公式

编写要求：

老师您好： 公式源码如下 100,COLORRED; 80,COLORLIRED; RSV:=(CLOSE-LLV(LOW,5))/(HHV(HIGH,5)-LLV(LOW,5))*100; K0:=SMA(RSV,3,1); K:=K0; D:=SMA(K0,2,1); J1:(3*K0-2*D),COLORYELLOW; J2:MA(J1,2),COLORRED; MAV:=(2*C+H+L)/4; VAR1:=LLV(LOW,21); VAR2:=HHV(HIGH,21); SK: EMA((MAV-VAR1)/(VAR2-VAR1)*100,8),COLORWHITE; SD: EMA(0.667*REF(SK,1)+0.333*SK,3),COLORCYAN; BIAS1:=(CLOSE-MA(CLOSE,6))/MA(CLOSE,6)*100; 短跌选股:IF(BIAS1<=-6,50,0); 求： 当天J1死叉J2; 次日J1又金叉J2。

解答：

?RSV:=(CLOSE-LLV(LOW,5))/(HHV(HIGH,5)-LLV(LOW,5))*100;

K0:=SMA(RSV,3,1);
