网友求助：

我的意思是只要在白线上 就有预警 不是上穿白线的时候才有预警 谢谢老师.............
VAR2:=CLOSE*VOL;
VAR3:=EMA((EMA(VAR2,3)/EMA(VOL,3)+EMA(VAR2,6)/EMA(VOL,6)
+EMA(VAR2,12)/EMA(VOL,12)+EMA(VAR2,24)/EMA(VOL,24))/4,13);
VAR4:=EMA(CLOSE,9);
SUP:1.06*VAR3,PRECIS2;
SDN:VAR3*0.94,PRECIS2;
LUP:EMA(VAR4*1.14,5),PRECIS2;
LDN:EMA(VAR4*0.86,5),PRECIS2;
买1:=C>O AND REF(C,5)<LDN AND C>LDN;
DRAWICON(买1,LDN,5);
买2:=O<REF(C,1) AND C>REF(O,1) AND REF(C,1)<REF(O,1) AND REF(((CLOSE/REF(CLOSE,1)-1)*100)<(-3),1) AND REF(C,1)<=SDN AND C>SDN;
DRAWICON(买2,SDN,1);
买3:=O>SDN AND LOW<LDN;
DRAWICON(买3,LDN,8);
买4:=C>O AND C<SDN AND REF(count(C<O,3)=3,1) AND (REF(CLOSE,4)-REF(CLOSE,1))>(LUP-SDN );
DRAWICON(买4,C,10);

 

解答如下：

VAR2:=CLOSE*VOL;
VAR3:=EMA((EMA(VAR2,3)/EMA(VOL,3)+EMA(VAR2,6)/EMA(VOL,6)
+EMA(VAR2,12)/EMA(VOL,12)+EMA(VAR2,24)/EMA(VOL,24))/4,13);
VAR4:=EMA(CLOSE,9);
SUP:=1.06*VAR3;
C>=SUP;
