将乖离底部出现底部时做成预警公式

编写要求：

DIFF:=EMA(CLOSE,3)-EMA(CLOSE,8); DEA:=EMA(DIFF,5); MACD:=2*(DIFF-DEA); A1:=EMA(DIFF,5)*100; A2:=((EMA(CLOSE,3)-EMA(CLOSE,8)))*100; A3:=IF(A2>0,A2,50),POINTDOT,COLORRED; A4:=IF(A2<0,A2,50),POINTDOT,COLORGREEN; 动能A:=A2,COLOR00FFFF,LINETHICK2; 动能B:=A1,COLORFFFF00,LINETHICK2; DRAWBAND(动能A,RGB(200,0,200),动能B,RGB(200,200,200)); STICKLINE(A2>0,0,A2,0.5,0),COLORRED; STICKLINE(A2<0,0,A2,0.5,1),COLORGREEN; VAR2:=(CLOSE-LLV(LOW,26))/(HHV(HIGH,26)-LLV(LOW,26))*100; VAR3:=SMA(SMA(VAR2,3,1),3,1); VAR4:=EMA(VAR3,5); AA:=VOL>=REF(V,1)*1.91 AND C>REF(C,1)*1.01; BB:=EMA(100*(C-LLV(LOW,34))/(HHV(H,34)-LLV(LOW,34)),3),COLOR1010FF; AA1:=STICKLINE(动能A<动能B,0,-3,2,0); BB1:=STICKLINE(动能A>动能B,0,3,2,0); 持币:AA1,COLOR00FF00; 持股:BB1,COLORRED; 底部:STICKLINE(CROSS(BB,9),0,10,1.7,0),COLORFF00FF; STICKLINE(CROSS(BB,9),10,20,1.5,0),COLOR00FFFF; STICKLINE(CROSS(BB,9),20,30,1,0),COLORRED; DRAWTEXT(CROSS(BB,9),30,'底部'),COLOR00FFFF; BIAS1:=(CLOSE-MA(CLOSE,6))/MA(CLOSE,6)*100; BIAS2:=(CLOSE-MA(CLOSE,12))/MA(CLOSE,12)*100; BIAS3:=(CLOSE-MA(CLOSE,24))/MA(CLOSE,24)*100; BIAS:=(BIAS1+2*BIAS2+3*BIAS3); 综合乖离:MA(BIAS,3),COLORFFFF00,LINETHICK0; BIAS底A:IF(综合乖离<-18,12,0),COLORFF00FF,LINETHICK2; BIAS底B:IF(综合乖离<-12,10,0), COLOR0000CC,LINETHICK2; BIAS底C:IF(综合乖离<-6,8,0),COLORFFFF00,LINETHICK2; BIAS底D:IF(综合乖离<0,6,0),COLOR00FFFF,LINETHICK2;

解答：

?BB:=EMA(100*(C-LLV(LOW,34))/(HHV(H,34)-LLV(LOW,34)),3);

底部:CROSS(BB,9);
