请根据这个副图公式给编写一个出现黄色信号的选股公式．通达信用

Var8:=EMA((Var4*1.25+Var5*1.23+Var6*1.2+Var11*0.55+Var2*0.55+Var3*0.65)/6,21);

VarE:=LLV(LOW,30);
VarF:=HHV(VarD,30);
Var10:=IF(MA(CLOSE,58),1,0);
aa3:=( EMA(IF(LOW<=VarE,(VarD+VarF*2)/2,0),3)/618*Var10) ;
bb:=aa3>ref(HHV(aa3,60),1);
cc:=hhv(aa3,60);
大底:=FILTER(aa3>10 ,1) ;
VA1:=VOL/((HIGH-LOW)*2-ABS(CLOSE-OPEN));
主买1:=IF(CLOSE>OPEN,VA1*(HIGH-LOW),IF(CLOSE<OPEN,VA1*((HIGH-OPEN)+(CLOSE-LOW)),VOL/2));
主卖1:=IF(CLOSE>OPEN,0-VA1*((HIGH-CLOSE)+(OPEN-LOW)),IF(CLOSE<OPEN,0-VA1*(HIGH-LOW),0-VOL/2));

aa6:=(主买1-(-主卖1))/主买1;
STICKLINE(大底>0 and c<o ,0,cc,4,0),COLORyellow;
因为这个副图的原理是:发出黄色信号后，第二天收阳线，尾盘买入。如果能给编写成上一个交易日出现黄色信号，当天收阳线的选股公式，就最好了，先谢谢了！

错误句 : XG:REF(大底,1)>0 AND REF(C,1)O
详细信息 : 未知字符串 大底
错误起始位置 : 7 ; 长度: 4

公式审核通不过啊
