X1:=2*EMA2(C,ROUND(N1/2,2))-EMA2(C,N1);
HULLMA1:EMA2(X1,ROUND(SQRT(N1),2));
X2:=2*EMA2(C,ROUND(N2/2,2))-EMA2(C,N2);
HULLMA2:EMA2(X2,ROUND(SQRT(N2),2));
X3:=2*EMA2(C,ROUND(N3/2,2))-EMA2(C,N3);
HULLMA3:EMA2(X3,ROUND(SQRT(N3),2));
3条均线同时向下的时候显示向下标志，发出B声音，谢谢

参考：
X1:=2*EMA2(C,ROUND(N1/2,2))-EMA2(C,N1);
HULLMA1:EMA2(X1,ROUND(SQRT(N1),2));
X2:=2*EMA2(C,ROUND(N2/2,2))-EMA2(C,N2);
HULLMA2:EMA2(X2,ROUND(SQRT(N2),2));
X3:=2*EMA2(C,ROUND(N3/2,2))-EMA2(C,N3);
HULLMA3:EMA2(X3,ROUND(SQRT(N3),2));
DRAWICON(CROSS(HULLMA1>REF(HULLMA1,1)&&HULLMA2>REF(HULLMA2,1)&&HULLMA3>REF(HULLMA3,1),0.5),HULLMA3,1);
CROSS(HULLMA1>REF(HULLMA1,1)&&HULLMA2>REF(HULLMA2,1)&&HULLMA3>REF(HULLMA3,1),0.5),SOUND('A');
DRAWICON(CROSS(HULLMA1<REF(HULLMA1,1)&&HULLMA2<REF(HULLMA2,1)&&HULLMA3<REF(HULLMA3,1),0.5),HULLMA3,2);
CROSS(HULLMA1<REF(HULLMA1,1)&&HULLMA2<REF(HULLMA2,1)&&HULLMA3<REF(HULLMA3,1),0.5),SOUND('B');
