[公式]請問繪製線段問題...

請問版上各位大大...
小弟想繪製圖檔中所說明之線段該如何完成呢??
謝謝^^

{MACD本文公式}
CC:=CLOSE ;
DIFF:=EMA( CC , 12 ) - EMA( CC , 26 ),PRECISION2 ;
DMACD:=EMA( DIFF , 9 ),PRECISION2,COLORYELLOW ;
DIF_MACD:=2 * ( DIFF - DMACD ) ,PRECISION2,LINETHICK0,COLORMAGENTA;
VERTLINE(REF(DIFF,1)>0 AND DIFF<0);

{DIF轉折向下公式}
DIF0:=DIFF>0 AND DIFF>REFX(DIFF,1) AND DIFF>REF(DIFF,1);
DRAWICON(DIF0,LOW*0.95,5);
