比如，畫了了五分均價圖，

{5分鐘圖顯示分時均價線}
A:=CURRBARSCOUNT;
A1:=DAY!=REF(DAY,1);
A2:=BARSLAST(A1)+1;
A4:=SUM(AMO,A2)/SUM(VOL,A2)/100;
BU1:=REF(CROSS(C,A4),1) AND C>A4;
BU2:=A4>REF(A4,1);
BU3:=DYNAINFO(17)>1;
{現價:IF(A<=CONST(A2),CLOSE,DRAWNULL),COLORBLUE,LINETHICK3;}
AA:=IF(INBLOCK('滬深A股'),1,0);
均價:IF(A<=CONST(A2),A4,DRAWNULL),COLORYELLOW,LINETHICK2;
前收盤:IF(A<=CONST(A2),DYNAINFO(3),DRAWNULL),COLORRED,LINETHICK2;
DRAWICON(A<=CONST(A2) AND TIME>0935 AND BU1,C*0.998,1);

如果看指數就成這樣了

如果我加入屏蔽, 結果均價線又看不到了，奇怪了？？為啥？？謝謝

AA:=IF(INBLOCK('滬深A股'),1,0);

均價:IF(A<=CONST(A2) and AA,A4,DRAWNULL),COLORYELLOW,LINETHICK2;

弄太多，是均價線。

AA:=IF(CODELIKE('399') OR CODELIKE('88'),0,1); 好用，inblock不好用
