請老師編寫壹個通達信資金流入流出的公式

N1:=5;N2:=20;

A:=(VOL-REF(VOL,1)*AMOUNT/1000000000);

{STICKLINE(A>0,0,A,6,0 ),COLORRED;

STICKLINE(A<0,0,A,6,0 ),COLORGREEN;}

當日資金凈流:A,LINETHICK3,LINETHICK0;

M3:=MA(A,N1);

資金累凈流:SUM(A,N2),LINETHICK3,COLORYELLOW;

ZJM:MA(資金累凈流,10);

DRAWICON(資金累凈流>=0 AND CROSS(資金累凈流,ZJM),ZJM,1);

DRAWICON(資金累凈流>=0 AND CROSS(ZJM,資金累凈流),ZJM,2);

引用公式，略有修改。{個人看法，僅供參考。}
