通达信看图说话左右投机之KDJ死叉后选（思路）

纯粹思路，勿做任何实际操做之依据。

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)
