以大盘MACD为背景条件的公式怎样写正确答案：
这是以大盘MACD为背景的主图
aa:=INDEXC;
DIFF:=EMA(AA,12) - EMA(AA,26);
DEA :=EMA(DIFF,9);
MACD:=2*(DIFF-DEA);
xma1:=MACD;xma2:=0;
xtj1:=CROSS(xma1,xma2) or xma1>xma2;
xtj2:=CROSS(xma2,xma1) or xma1<xma2;
FILLRGN(xtj1,SYSPARAM(5),SYSPARAM(4)),ColorDB3FCA;
FILLRGN(xtj2,SYSPARAM(5),SYSPARAM(4)),Color528608;
ktj:=(CLOSE>OPEN or CLOSE=OPEN and CLOSE>REF(CLOSE,1));
STICKLINE(ktj,HIGH,LOW,0.1,1),colorred;
STICKLINE(ktj,CLOSE,OPEN,7,1),colorred;
STICKLINE(NOT(ktj),HIGH,LOW,0.1,0),colorcyan;
STICKLINE(NOT(ktj),CLOSE,OPEN,7,0),colorcyan;
ma5:MA(CLOSE,5);
ma10:MA(CLOSE,10);
ma20:MA(CLOSE,20);
ma30:MA(CLOSE,30);
aa:=sumbars(vol,capital);
平均成本:sum(v*c,aa)/sum(v,aa),linethick1;
