简单精准易明（变态KDJ底部）源码副图

{股海网提供：www.guhai.com.cn}

本公式是普通（KDJ）修改成变态版专为趋势探底用简单易明，请各位高人多多给点意见，使其更加完美，造福广大的股友们赚钱步步高升！

超底:20,COLORLIGREEN;
底线:40,COLORLICYAN;
强弱分界线:80,COLORBLUE;
顶线:120,COLORLIRED;
超顶:140,COLORLIMAGENTA;
VAR1:=(H+L+O+C*2)/5;
VAR2:=EMA(VAR1,21);
VAR3:=STD(VAR1,23);
VAR4:=EMA(VAR1,2);
VARA:=(VAR1-VAR2)*100/VAR3;
RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K:EXPMA(EXPMA(EXPMA(RSV,2),3),3),COLORCYAN;
D:SMA(K,2,1),COLORWHITE;
J:3.5*K-2*D,COLORYELLOW,LINETHICK2;
IF(J>REF(J,1),J,DRAWNULL),COLORRED,LINETHICK2;
IF(J<REF(J,1),J,DRAWNULL)COLORGREEN,LINETHICK2;
DRAWICON(FILTER(J>REF(J,1)AND J<REF(J,3)
AND J<K AND VAR4>REF(VAR4,1)
AND K>=REF(K,1)AND J<40
OR CROSS(J,K)AND CROSS(J,D)
AND J<40 OR J>REF(J,1)AND J<40,7), J*0.8,1);
DRAWICON(FILTER(J<=REF(J,1) AND J>80,8), J*1.2,2);　

下面这个与上面有少少不同，最后一句用到未来（ZIG）作参考趋势，不影响本身公式准确度。
