不好意思自問自答一下, IB 有回覆告知, 雖然是免費的服務 (not fee liable),
不過還是要線上簽署相關文件.
大概是怕被第三方修改資訊之類的.
Dear Client,
You received the below emails because your request NYSE Order Imbalance data.
While these services are not fee-liable, they do require prior approval from
the NYSE. If you would still like to receive these services,
please complete the agreement.
If not, let me know and I will cancel your request.
Regards,

※ 引述《tipsofwarren (tipsofwarren)》之銘言：
: IB 開戶後, 各種 Data Source 我只選取 "Fees Wavied" 的項目,
: 然後就收到一封 email, 希望我線上數位簽署
: "Agreement for Receipt of Consolidated Network A Data and NYSE Market Data"
: 不知道是否簽下去, 就會被多收取什麼資料服務費之類的?
: (我的帳戶只有看到 NYSE Imbalances 的資料申請還在 Pending 狀態)
: 感謝提點.
