网友求助：
各位老师好，麻烦请将下面这个通达信的分时公式改写为飞狐的，并写一个当出现“机构”买点（也就是图中的红线上穿绿线，出现红色实心圆点）时的预警公式，适用周期：1分钟。适用软件：飞狐。谢谢！！

A1:=(DVOL/C)/2,NODRAW;
A2:=SUM(IF(A1>100 AND CLOSE>REF(CLOSE,1),A1,0),0);
A3:=SUM(IF(A1>100 AND CLOSE<REF(CLOSE,1),A1,0),0);
A4:=SUM(IF(A1<100 AND CLOSE>REF(CLOSE,1),A1,0),0);
A5:=SUM(IF(A1<100 AND CLOSE<REF(CLOSE,1),A1,0),0);
A6:=A2+A3+A4+A5;
机买:(A2/A6)*100,LINETHICK2,COLORRED;
机卖:(A3/A6)*100,LINETHICK2,COLORGREEN;
散买:(A4/A6)*100,LINETHICK0;
散卖:(A5/A6)*100,LINETHICK0;
主力差:机买-机卖,LINETHICK2,NODRAW;
散户差:散买-散卖,LINETHICK0,NODRAW;
DRAWTEXT(主力差>0 AND REF(主力差,1)<=0,C*0.85,'●机构'),COLORRED;
DRAWTEXT(主力差<0 AND REF(主力差,1)>=0,-C*0.85,'○机构'),COLORWHITE;
DRAWTEXT(散户差>0 AND REF(散户差,1)<=0,C*0.15,'▲散户'),COLORCYAN;
DRAWTEXT(散户差<0 AND REF(散户差,1)>=0,-C*0.15,'△散户'),COLORWHITE;
解答如下：
A1:=(VOL/C)/2;
A2:=SUM(IF(A1>100 AND CLOSE>REF(CLOSE,1),A1,0),0);
A3:=SUM(IF(A1>100 AND CLOSE<REF(CLOSE,1),A1,0),0);
A4:=SUM(IF(A1<100 AND CLOSE>REF(CLOSE,1),A1,0),0);
A5:=SUM(IF(A1<100 AND CLOSE<REF(CLOSE,1),A1,0),0);
A6:=A2+A3+A4+A5;
机买:(A2/A6)*100,LINETHICK2,COLORRED;
机卖:(A3/A6)*100,LINETHICK2,COLORGREEN;
散买:(A4/A6)*100,LINETHICK0;
散卖:(A5/A6)*100,LINETHICK0;
主力差:机买-机卖,LINETHICK0;
散户差:散买-散卖,LINETHICK0;
DRAWTEXT(主力差>0 AND REF(主力差,1)<=0,C*0.85,'●机构'),COLORRED;
DRAWTEXT(主力差<0 AND REF(主力差,1)>=0,-C*0.85,'○机构'),COLORWHITE;
DRAWTEXT(散户差>0 AND REF(散户差,1)<=0,C*0.15,'▲散户'),COLORCYAN;
DRAWTEXT(散户差<0 AND REF(散户差,1)>=0,-C*0.15,'△散户'),COLORWHITE;
