这个指标来源于MACD论坛，我认为非常好，但是不知如何用他选股，请各位大侠指教，谢谢！！！！！
指标名称：OBVS
N=20; M=4;
指标源码如下：z:=zig(4,n);
dd:=ALL((ref(z,1)ref(z,1)),1);{所有的波段低点}
gg:=ALL(ref(z,1)>ref(z,2) and z
gw:=barslast(gg);{计算高点到低点的天数}
VERTLINE(gw=0,3),Color0000FF;
VERTLINE(dw=0,3),Color00FF00;
a:=if(m=1,c,if(m=2,amount/v/100,if(m=3,ema(c,5),ema(amount/v/100,5))));
Lg:=if(capital,capital,1);
bv:=IF(a>REF(a,1),V/Lg,IF(a
obv:sum(bv,gw)*100,PRECIS2,linethick0,coloryellow;{//obv值}
增仓阶段:sum(obv,gw)/gw,PRECIS2,colorred,linethick0;{//pobv值}
减仓阶段:sum(obv,gw)/gw,PRECIS2,ColorFFF600,linethick0;
VAR1:=VOL/((HIGH-LOW)*2-ABS(CLOSE-OPEN));
当日获利％:WINNER(CLOSE)*100,PRECIS0,LINETHICK0,Color0087DD;
0,ColorFFFFFF,POINTDOT,PRECIS0;
PARTLINE(增仓阶段,gw>1),PRECIS2,colorred;{画POBV}
partline(增仓阶段,gw>1 and 增仓阶段
PARTLINE(obv1,gw>1),coloryellow;{画POBV}
DRAWTEXT(dw=0,0-0.98,'减仓阶段 减:'+obv),PRECIS2,ColorFFFF0F,ALIGN2,VALIGN0;{显示obv}
DRAWTEXT(gw=0,0,'增仓阶段 增:'+(ref(obv,1)+bv)),ColorFF00FF,ALIGN2,VALIGN2,PRECIS2{保留小数位数};{显示obv};
