请老师把'铁底出现'写成选股预警公式

Question

ZYX1:="DMI.PDI"(12,6);

0,COLORRED;
STICKLINE(FILTER(ZYXF=1,5) AND 多空<-10,50,0,10,0),COLORRED;

STICKLINE(多空<-10,0,多空,1,0),COLORYELLOW;
STICKLINE(多空>10,0,多空,1,0),COLORYELLOW;

Answer 1

ZYXF:=BARSLAST(CROSS(ZIG(3,15),MA(ZIG(3,15),2)))+1;
铁底出现了:ZYXF=3 AND H>REF(HHV(H,3),1);
-------------------------------------------
注:原指标的所谓铁底是大涨了以后回头来确认其为铁底,
所以公式
ZYXF:=TROUGHBARS(3,15,1)<4;
铁底选股:FILTER(ZYXF=1,3);

是不可能选到股的

Answer 2

ZYXF:=TROUGHBARS(3,15,1)<4;
铁底选股:FILTER(ZYXF=1,3);
