网友求助：
在出现 B字和黄星星B字 买点时分别做个选股 谢谢
A:=AMOUNT/V/100;
VARA:=EMA((((A-EMA(A,13))/EMA(A,13))*(0-100)),5);
QQ:=EMA(((VARA/10)+EMA(A,13)),0);
行情线:=MA(A,1);
重心:=(C+0.618*REF(C,1)+0.382*REF(C,1)+0.236*REF(C,3)+0.146*REF(C,4))/2.382;
【操盘线】:EMA(((SLOPE(C,22)*20)+C),55),COLORYELLOW,LINETHICK4;
【黄金线】:IF(重心>=【操盘线】,【操盘线】,DRAWNULL),COLORRED,LINETHICK2;
【空仓线】:IF(重心<【操盘线】,【操盘线】,DRAWNULL),COLORCYAN,LINETHICK2;
{DRAWTEXT(ISLASTBAR,【操盘线】,'【操盘线】'),COLORRED;}
{引:EMA(CLOSE,2),LINETHICK1,COLORMAGENTA;

变:EMA(CLOSE,5),LINETHICK2,COLORYELLOW;
金:IF(变>REF(变,1),变,DRAWNULL),COLORRED,LINETHICK2;
空:IF(变<REF(变,1),变,DRAWNULL),COLORGREEN,LINETHICK2;
{DRAWTEXT(ISLASTBAR,变,'【雷达线】'),COLORRED;}
{顶底信号}
DA:=(EMA(H,1)+EMA(L,1)+EMA(H,1)+EMA(H,1))/4;
DB:=EMA(REF(HHV(H,25),1),2),COLORGREEN,LINETHICK1;
{DRAWTEXT(CROSS(DB,DA),DB,'←险'),COLORGREEN,LINETHICK1;}
DRAWTEXT(CROSS(DA,【操盘线】),【操盘线】-0.5,'★B'),COLORYELLOW,LINETHICK1;
{涨跌停显示}
涨停:=IF((C-REF(C,1))*100/REF(C,1)>=(10-0.01*100/REF(O,1)),1,0);
STICKLINE(涨停,O,C,3,0),COLORYELLOW;
ZDF:=(C-REF(C,1))/REF(C,1)*100;
STICKLINE(ZDF<-9.9,O,C,3,0),COLORGREEN;
DA9:=(EMA(C,1)+EMA(C,2)+EMA(C,3)+EMA(C,4))/4;
DB9:=(EMA(C,10)+EMA(C,20)+EMA(C,40)+EMA(C,80))/4;
DRAWTEXT(CROSS(DA9-DB9,0),L*0.98,'B'),COLORYELLOW;
JH9:=SMA(MAX(C-REF(C,1),0),5,1)/SMA(ABS(C-REF(C,1)),5,1)*100;
DRAWTEXT(CROSS(84,JH9),H*1.02,'☆S'),COLORGREEN;
解答如下：
B字选股
DA9:=(EMA(C,1)+EMA(C,2)+EMA(C,3)+EMA(C,4))/4;
DB9:=(EMA(C,10)+EMA(C,20)+EMA(C,40)+EMA(C,80))/4;
XG:CROSS(DA9-DB9,0);
黄星B字选股
【操盘线】:=EMA(((SLOPE(C,22)*20)+C),55);
DA:=(EMA(H,1)+EMA(L,1)+EMA(H,1)+EMA(H,1))/4;
XG:CROSS(DA,【操盘线】);
