请老师如图解决 (文华财经WH6赢顺V6.7)

 最后一行加上下面代码：

DRAWCOLORKLINE(SARLINE>0,COLORRED,0);
DRAWCOLORKLINE(SARLINE<0,COLORCYAN,0);

参考：

N:=4;
STEP:=2;
MVALUE:=20;
STEP1:=STEP/100;
MVALUE1:=MVALUE/100;
SARLINE:=SAR(N,STEP1,MVALUE1),CIRCLEDOT;
IF(SARLINE>0,SARLINE,NULL),COLORRED,CIRCLEDOT;
IF(SARLINE<0,-SARLINE,NULL),COLORCYAN,CIRCLEDOT;
DRAWCOLORKLINE(SARLINE>0,COLORRED,0);
DRAWCOLORKLINE(SARLINE<0,COLORCYAN,0);
