Level-2风向标（附图）
网上搜来的原码??请老师作成盘中分时，柱状指标

第一步：创建分笔成交统计的个股数据
{龙虎看盘（源码）:}

DRAWGBKLAST(C>0,STRIP(RGB(0,0,0),RGB(0,0,153),0)),color33ff66;
DRAWTEXTREL(20,30,STKLABEL),LINETHICK4,Colorffff00;
DRAWTEXTREL(120,30,STKNAME),LINETHICK4,Color00ffff;

a:=BUYVOL*DYNAINFO(7)/100;
bz:=SUM(a,0);
b:=SELLVOL*DYNAINFO(7)/100;
sz:=SUM(b,0);
z:=bz sz;
cz:=bz-sz;
当日个股总买:bz,COLOR0000FF,LINETHICK2;{扩展数据12}
当日个股总卖:sz,COLOR00FF00,LINETHICK2;;{扩展数据13}
当日个股总额:bz sz,COLOR0066FF,LINETHICK2;;{扩展数据14}
当日总净买卖:cz,COLOR00FFFF,LINETHICK2;;{扩展数据15}

第二步：创建扩展数据

个股bz:EXTDATA(12);
个股sz:EXTDATA(13);
个股z:EXTDATA(14);
个股总净:EXTDATA(15);

第三步：创建自定义数据并实现输出
