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;
