网友求助：
请老师在抄底指标的‘红箭头’处改写个选股公式，是否可以把‘红箭头’的出现向后移一天？
源码：
VAR1:=AMOUNT/vol/7;
VAR2:=(3*HIGH+LOW+OPEN+2*CLOSE)/7;
VAR3:=SUM(AMOUNT,N)/VAR1/7;
VAR4:=DMA(VAR2,VOL/VAR3);
抄底:(CLOSE-VAR4)/VAR4*100,COLORLIMAGENTA;
DRAWICON(crOSS(-7.0,抄底),抄底,1);
参数： N 1 300 10
解答如下：
VAR1:=AMOUNT/VOL/7;
VAR2:=(3*HIGH+LOW+OPEN+2*CLOSE)/7;
VAR3:=SUM(AMOUNT,10)/VAR1/7;
VAR4:=DMA(VAR2,VOL/VAR3);
抄底:=(CLOSE-VAR4)/VAR4*100A;
REF(CROSS(-7.0,抄底),1);
VAR2:=(3*HIGH+LOW+OPEN+2*CLOSE)/7;
VAR3:=SUM(AMOUNT,10)/VAR1/7;
VAR4:=DMA(VAR2,VOL/VAR3);
抄底:=(CLOSE-VAR4)/VAR4*100A;
REF(CROSS(-7.0,抄底),1);
