本次更版 XML的輸出 於CHARTDATA的描述部分 有些微調整

原本內容與TYPE屬性相同

<CHARTDATA TYPE='60Min' TIME='2017-12-18 03:37:30.611 GMT'>60Min</CHARTDATA>

新版則改用轉檔所用之主檔名替代

<CHARTDATA TYPE='60Min' TIME='2017-12-18 03:37:30.611 GMT'>TX-201712</CHARTDATA>

老實說,這類資料傳輸格式大同小異,其實JSON不一定會比較省資料量,

主要還是得看資料的編排方式, 就像上面的內容,

JSON裏的O,H,L,C,V,N和內容值如果都使用雙引號的話其實檔案還比XML大...
