请老师做个四量图的选股公式，谢谢！！

要求：四条成交量带都为红时，xg=1（不分是不是第一天由绿变红，只要四天成交量带都是红色的，xg就等于1），源码如下：

MID:=(3*CLOSE+LOW+OPEN+HIGH)/6;
牛线:=(20*MID+19*REF(MID,1)+18*REF(MID,2)+17*REF(MID,3)+16*REF(MID,4)+15*REF(MID,5)+14*REF(MID,6)+13*REF(MID,7)+12*REF(MID,8)+11*REF(MID,9)+10*REF(MID,10)+9*REF(MID,11)+8*REF(MID,12)+7*REF(MID,13)+6*REF(MID,14)+5*REF(MID,15)+4*REF(MID,16)+3*REF(MID,17)+2*REF(MID,18)+REF(MID,20))/210,COLORGREEN{COLORRED};
马线:=MA(牛线,6),COLORMAGENTA{COLORYELLOW};
STICKLINE(C>牛线,2.5,4,8,0),COLORRED{COLORGREEN},LINETHICK2;
STICKLINE(C<马线,2.5,4,8,0),COLORGREEN{COLORRED},LINETHICK2;
STICKLINE(牛线>=C AND C>=马线,2.5,4,8,0),COLORGREEN{COLORMAGENTA}{COLORYELLOW},LINETHICK2;
A:=MAX(MA(C,60),MA(C,120));
B:=MIN(MA(C,60),MA(C,120));
STICKLINE(C>=A,0.5,2,8,0),COLORRED{COLORGREEN},LINETHICK2;
STICKLINE(C<=B,0.5,2,8,0),COLORGREEN{COLORRED},LINETHICK2;
STICKLINE(A>=C AND C>=B,0.5,2,8,0),COLORGREEN{COLORMAGENTA}{COLORYELLOW},LINETHICK2;

{R:=0;}
E:=MAX(MA(C,45),MA(C,90));
F:=MIN(MA(C,45),MA(C,90));
STICKLINE(C>E,-1.5,0,8,0),COLORRED{COLORGREEN},LINETHICK2;
STICKLINE(C<F,-1.5,0,8,0),COLORGREEN{COLORRED},LINETHICK2;
STICKLINE(E>=C AND C>=F,-1.5,0,8,0),COLORGREEN{COLORMAGENTA}{COLORYELLOW},LINETHICK2;
J:=MAX(MA(C,30),MA(C,60));
K:=MIN(MA(C,30),MA(C,60));
STICKLINE(C>J,-3.5,-2,8,0),COLORRED{COLORGREEN},LINETHICK2;
