双底说明一下 如果在牛市就用下面这个主图选股 幅图，N我设置15天 适个人喜好自己修改20或者13或者N天都可以的。
 

主图

N:=15;

T:=LLVBARS(L,N);

HT:=HHVBARS(H,N);

TT:=BARSLAST(T=0);

XG:=T=0 AND REF(TT,1)<20 AND L>REF(L,REF(TT,1));

XGT:=BARSLAST(XG);

QF:=BACKSET(XG=1,HT+1);

QFT:=BARSLAST(CROSS(QF=1,0.5));

DRAWLINE(QFT=0,H,XG,L,0),COLORYELLOW;

QF1:=BACKSET(QFT=0,TT+1);

QF1T:=BARSLAST(CROSS(QF1=1,0.5));

DRAWLINE(QF1T=0,L,QFT=0,H,0),COLORYELLOW;

STICKLINE(QF1T=0,C,O,1.8,0),COLORWHITE;

STICKLINE(QF1T=0,H,L,0,0),COLORWHITE;

DRAWTEXT(QF1T=0,H*1.02,VARCAT(VARCAT('第一底价',VAR2STR(REF(L,QF1T),2)),'元'))COLORYELLOW;

STICKLINE(XG,C,O,1.8,0),COLORWHITE;

STICKLINE(XG,H,L,0,0),COLORWHITE;

DRAWTEXT(XGT=0,H*1.04,VARCAT(VARCAT('双底价',VAR2STR(REF(L,XGT),2)),'元'))COLORYELLOW;

DRAWICON(XG,L*0.94,1);
