VAR1:=(2*CLOSE+HIGH+LOW+OPEN)/5;
A1:=(EMA(VAR1,14)+EMA(VAR1,14)+EMA(VAR1,14)+EMA(VAR1,14))/4,COLORRED;
IF(A1>=REF(A1,1),A1,DRAWNULL),COLORRED;
IF(A1<=REF(A1,1),A1,DRAWNULL),COLORGREEN;
A2:EMA(A1,2),COLORRED;
IF(A2>=REF(A2,1),A2,DRAWNULL),COLORRED;
IF(A2<=REF(A2,1),A2,DRAWNULL),COLORGREEN;
A3:EMA(A2,2.5),COLORRED;
IF(A3>=REF(A3,1),A3,DRAWNULL),COLORRED;
IF(A3<=REF(A3,1),A3,DRAWNULL),COLORGREEN;
A4:EMA(A2,3),COLORRED;
IF(A4>=REF(A4,1),A4,DRAWNULL),COLORRED;
IF(A4<=REF(A4,1),A4,DRAWNULL),COLORGREEN;
A5:EMA(A2,4),COLORRED;
IF(A5>=REF(A5,1),A5,DRAWNULL),COLORRED;
IF(A5<=REF(A5,1),A5,DRAWNULL),COLORGREEN;

老师如果我这样写
A4>=REF(A4,1)   A4<=REF(A4,1)
信号会不会闪烁
