模型满足条件问题咨询　[文华财经]

老师，你好！以下指标在豆油2205合约3分钟周期截图中白色垂直线对应的最低价格9872应该是满足条件要出信号，怎么没有出信号？请老师看看是什么情况？ 

DIFF:=(EMA(CLOSE,12)-EMA(CLOSE,26));
DEA:=(EMA(DIFF,9)),COLORYELLOW,NOTEXT;
MACD:=((DIFF-DEA)*2),NODRAW;

A991:=H<HV(H,30)&&MACD>HV(MACD,30);//顶背离&&ISUP
B991:=L<LV(L,30)&&MACD>LV(MACD,30);//底背离&&ISDOWN
B9911:=L<LLV(L,30)&&MACD>LLV(MACD,30);//底背离&&ISDOWN

AX1:=BACKSET(ISLASTBAR,SUMBARS(A991,1));//AX&&
AX2:=BACKSET(ISLASTBAR,SUMBARS(B991,1));//AX1&&TP1

DRAWTEXT(A991&&AX1,16,'要跌→'),COLORWHITE,ALIGN2,VALIGN0;//'该涨不涨就要跌→'
DRAWGBK1(A991&&AX1,RGB(0,64,64)),VALIGN0;//绿色顶背离背景色

//B99:=L<LLV(L,30)&&MACD>LLV(MACD,30);//底背离&&ISDOWN

DRAWTEXT(B991&&AX2,14,'要涨→'),COLORWHITE,ALIGN2,VALIGN2;//'该跌不跌就要涨→'
DRAWGBK1(B991&&AX2,RGB(128,0,128)),VALIGN0;//绿色顶背离背景色//,RGB(128,0,64)//,RGB(0,64,0)

DRAWGBK1(B9911,RGB(128,0,128)),VALIGN0;//绿色顶背离背景色//,RGB(128,0,64)//,RGB(0,64,0)
