老师 ，请帮助将箭头表示 改成划线标识！

 老师 ，请帮助将箭头表示 改成划线标识：

ICO4 用红色竖线；

ICO5用绿色竖线；

源码：

DIFF : EMA(CLOSE,12) - EMA(CLOSE,26),NODRAW;
DEA  : EMA(DIFF,9),NODRAW;
MACD:2*(DIFF-DEA),NODRAW;

C1:=VALUEWHEN(CROSS(DIFF,DEA),LLVBARS(DIFF,BARSLAST(CROSSDOWN(DIFF,DEA))));
C2:=VALUEWHEN(CROSSDOWN(DIFF,DEA),HHVBARS(DIFF,BARSLAST(CROSS(DIFF,DEA))));
DRAWICON(CROSS(BACKSET(CROSS(DIFF,DEA),C1+1),0.5),2*DIFF,'CO4';
DRAWICON(CROSS(BACKSET(CROSSDOWN(DIFF,DEA),C2+1),0.5),2*DIFF,'CO5';

谢谢！
