请高手将下面公式改为同花顺的分时指标及选股公式

A12:=(DVOL/C)/2,NODRAW;
A22:=SUM(IF(A12>100 AND CLOSE>REF(CLOSE,1),A12,0),0);
A32:=SUM(IF(A12>100 AND CLOSE<REF(CLOSE,1),A12,0),0);
A42:=SUM(IF(A12<100 AND CLOSE>REF(CLOSE,1),A12,0),0);
A52:=SUM(IF(A12<100 AND CLOSE<REF(CLOSE,1),A12,0),0);
A62:=A22+A32+A42+A52;
机买:(A22/A62)*100,LINETHICK2,colorred;
机卖:(A32/A62)*100,LINETHICK2,colorgreen;
散买:(A42/A62)*100,LINETHICK0;
散卖:(A52/A62)*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;

1、改成同花顺能用的分时指标公式
2、改成同花顺能用的选股公式，主力差大于0时为选股条件。
