将文件放到  安装目录\T0002\signals 文件夹下，作用是在通达信主图上显示公司主营业务,免去来回F10的麻烦
 哈，怎么用不用我多说吧，结合下面的公式:
 
{均线}
 MA5:MA(CLOSE,5),COLORWHITE;
 MA10:MA(CLOSE,10),COLORYELLOW;
 MA20:MA(CLOSE,20),COLORMAGENTA;
 MA60:MA(CLOSE,60),COLORCYAN;
 {涨跌停标识}
 C2:=REF(C,1);
 涨停:=IF(C/C2>=1.095,1,0);
 STICKLINE(涨停,OPEN,CLOSE,3,0),COLORYELLOW;
 STICKLINE(涨停,H,L,0.1,0),coloryellow;
 跌停:=IF((C2-C)/C2>=0.09,1,0);
 STICKLINE(跌停,OPEN,CLOSE,3,0),COLORBLUE;
 STICKLINE(跌停,H,L,0.1,0),colorblue;
 {公司信息}
 利润同比:=STRCAT('利润同比：',CON2STR(FINANCE(43),2));
 收入同比:=STRCAT('收入同比：',CON2STR(FINANCE(44),2));
 主营利润率:=STRCAT('主营利润率：',CON2STR(FINANCE(23)/FINANCE(20)*100,2));
 所属地域:=STRCAT('所属地域：',DYBLOCK);
 所属行业:=STRCAT('所属行业：',HYBLOCK);
 所属概念:=STRCAT('所属概念：',GNBLOCK);
 所属风格:=STRCAT('所属风格：',FGBLOCK);
 主营业务:=STRCAT('主营业务：',EXTERNSTR(0,1));
 DRAWTEXT_FIX(1,0.00,0.01,0,利润同比),COLORWHITE;
 DRAWTEXT_FIX(1,0.11,0.01,0,收入同比),COLORMAGENTA;
 DRAWTEXT_FIX(1,0.22,0.01,0,主营利润率),COLOR0080FF;
 DRAWTEXT_FIX(1,0.00,0.05,0,所属地域),COLORYELLOW;
 DRAWTEXT_FIX(1,0.00,0.09,0,所属行业),COLORYELLOW;
 DRAWTEXT_FIX(1,0.00,0.13,0,所属概念),COLORYELLOW;
 DRAWTEXT_FIX(1,0.00,0.17,0,所属风格),COLORCYAN;
 DRAWTEXT_FIX(1,0.00,0.21,0,主营业务),COLORGREEN;
 
然后在 功能-公式系统-自定义数据管理器-新建  
数据号：1
 属性：外部数据  
名称：主营业务
 把以上代码新建公式，在主图叠加就能显示了
