把红牛抬头改成选股公式

编写要求：

主力净买量:(LARGEINTRDVOL-LARGEOUTTRDVOL),NODRAW;{DRAWRECTABS(0,0,920,1,RGB(200,20,50)),COLOR2050CC}; 净额:=主力净买量/VOL*AMOUNT/10000; {流入净额:=净额1*1.25+净额2*1.5}; 能量:=净额/MA(V,5)*100,LINETHICK1; DRAWBAND(能量,RGB(240,240,0),-0.10,RGB(00,200,00))}; NL:IF(能量>=1,1,能量); DRAWBAND(NL,RGB(200,0,0),0,RGB(0,200,0)); 买力:(净额)*0.5/V*100,LINETHICK1,COLOR555555; A:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100; K:=SMA(A,4,1); D:=SMA(K,3,1); J:=(3*K-2*D); 红牛:J/10,COLOR0000EE; 拓虎:K/10,COLORAAAAAA; 红牛抬头:REF(J,2)>REF(J,1) AND J>REF(J,1),LINETHICK0,COLOR0000FF; B:红牛抬头 AND 能量>0.8 AND (净额)>300 AND (J<40 OR (J<80 AND 能量>3))AND CAPITAL/100>6000 AND CAPITAL/100<45000,LINETHICK0; DRAWTEXT(B,0,'B');

解答：

?主力净买量:=(LARGEINTRDVOL-LARGEOUTTRDVOL);

净额:=主力净买量/VOL*AMOUNT/10000;
