這個指標提示有未來函數，如何找到并去除未來函數，還有我一使用就提示“兩個操作數不可以為空，某個變量或函數未返回數據”什么意思，如何解決？？？

文華技術人員：
上述模型中沒有使用到未來函數，提示錯誤是因為劃線函數不能定義變量，為您修改如下：

A1:=BARSLAST(REF(CROSS(DIF,DEA),1));
底背離:=REF(CLOSE,A1+1)>CLOSE AND DIF>REF(DIF,A1+1) AND CROSS(DIF,DEA);

文華客服： 非常感謝，指標可以使用了，但是以前背離會自動畫線的，現在沒了，能加上這個功能嗎

已經麻煩2次了，有點不好意思，但是，指標有點錯亂了，我本想讓指標自動顯示頂底背離，并劃線，現在底背離不畫線，頂背離無論多遠都畫線，麻煩您抬手改下，可以為相鄰頂底背離，并劃線就可以了，再次感謝
