 AA:=SETTLE>REF(SETTLE,1);
BB:=SETTLE<REF(SETTLE,1);
AAA:=REF(AA,1)&&BB;//均价线从原来是向上走开始向下转向走
BBB:=REF(BB,1)&&AA;//均价线从原来是向下走开始向上转向走
DRAWTEXT(BBB&&BACKSET(ISLASTBAR,DAYBARPOS),SETTLE,'★'),COLORMAGENTA,VALIGN1,ALIGN1,FONTSIZE18;
DRAWTEXT(AAA&&BACKSET(ISLASTBAR,DAYBARPOS),SETTLE,'★'),COLORGREEN,VALIGN1,ALIGN1,FONTSIZE18;
DRAWCOLORLINE(BB,SETTLE,COLORGREEN,COLORMAGENTA);
老师，以上是1分钟有标注的日内均价SP线，如果我只要画当日的线，前面天数的都不画，公式要如何修改？

参考：

 

NG:=BACKSET(ISLASTBAR,DAYBARPOS);
AA:=SETTLE>REF(SETTLE,1);
BB:=SETTLE<REF(SETTLE,1);
AAA:=REF(AA,1)&&BB;//均价线从原来是向上走开始向下转向走
BBB:=REF(BB,1)&&AA;//均价线从原来是向下走开始向上转向走
DRAWTEXT(BBB&&BACKSET(ISLASTBAR,DAYBARPOS),SETTLE,'★'),COLORMAGENTA,VALIGN1,ALIGN1,FONTSIZE18;
DRAWTEXT(AAA&&BACKSET(ISLASTBAR,DAYBARPOS),SETTLE,'★'),COLORGREEN,VALIGN1,ALIGN1,FONTSIZE18;

DRAWLINE3(NG && DAYBARPOS>=2 && BB,REF(SETTLE,1),1,NG && DAYBARPOS>=2 && BB,SETTLE,0,0),COLORMAGENTA;
DRAWLINE3(NG && DAYBARPOS>=2 && AA,REF(SETTLE,1),1,NG && DAYBARPOS>=2 && AA,SETTLE,0,0),COLORGREEN;
