VBA抓大盤指數與期貨指數畫圖

前一篇VBA抓大盤指數與漲跌家數畫圖，是否學會將三條曲畫在同一張圖上呢?如果還不會可以再參考這篇，一樣有問題趕快舉手發問，拖到後面可是救不了你。
這篇我們抓取大盤指數與期貨指數，並計算兩者中間價差，有興趣的可以參考以下程式碼。

Option Explicit

Const xlStartYear As Integer = 2014
Const xlStartMonth As Integer = 1
Const xlStartDay As Integer = 1
Const xlFilePath As String = "C:\期貨下載資料\"

        .Cells(1, 3) = "期貨指數"
        .Cells(1, 4) = "指數價差"

    End With
