老師，你好！以下指標在豆油2205合約3分鐘周期截圖中白色垂直線對應的最低價格9872應該是滿足條件要出信號，怎么沒有出信號？請老師看看是什么情況？?

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);//頂背離&&ISUP
B991:=L<LV(L,30)&&MACD>LV(MACD,30);//底背離&&ISDOWN
B9911:=L<LLV(L,30)&&MACD>LLV(MACD,30);//底背離&&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;//'該漲不漲就要跌→'
DRAWGBK1(A991&&AX1,RGB(0,64,64)),VALIGN0;//綠色頂背離背景色

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

DRAWTEXT(B991&&AX2,14,'要漲→'),COLORWHITE,ALIGN2,VALIGN2;//'該跌不跌就要漲→'
DRAWGBK1(B991&&AX2,RGB(128,0,128)),VALIGN0;//綠色頂背離背景色//,RGB(128,0,64)//,RGB(0,64,0)

DRAWGBK1(B9911,RGB(128,0,128)),VALIGN0;//綠色頂背離背景色//,RGB(128,0,64)//,RGB(0,64,0)
