左右投机之KDJ死叉后选（思路）

CTJ01:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
 KCTJ:=SMA(CTJ01,3,1);
 DCTJ:=SMA(KCTJ,3,1);
 JCTJ:=3*KCTJ-2*DCTJ;

JCC:=IF(CROSS(JCTJ,KCTJ),JCTJ,0);
 SCC:=IF(CROSS(KCTJ,JCTJ),JCTJ,0);

KDJHX1:=DRAWLINE(JCC>0,JCC,SCC>0,SCC,0)COLORYELLOW;
 KDJHX2:=DRAWLINE(SCC>0,SCC,JCC>0,JCC,0)COLORYELLOW;
 KDJHX1=DRAWNULL AND KDJHX2=DRAWNULL AND SUM(C>O,5)>2;
