老师,帮忙做个预警公式,图中趋势线在有庄影后第一次上0轴,

VAR2:=REF(LOW,1);VAR3:=SMA(ABS(LOW-VAR2),3,1)/SMA(MAX(LOW-VAR2,0),3,1)*100;
VAR4:=EMA(IF(CLOSE*1.2,VAR3*10,VAR3/10),3);VAR5:=LLV(LOW,38);
VAR6:=HHV(VAR4,38);VAR7:=IF(LLV(LOW,90),1,0);
VAR8:=EMA(IF(LOW0;
趋势线:=(CLOSE-MA(CLOSE,40))/MA(CLOSE,40)*100;
AA:=CROSS(趋势线,0) AND 有庄的影子;
XG:FILTER(AA,10);

(你试试看)
