I have a technical question which I hope some of the more technically astute members of Elite trader will be able to answer. Will Interactive Brokers be able to identify your location when you log in and track trades based on your IP Address. The reason I ask is of no malicious agenda but rather a complex tax related matter governing e-commerce transaction with hedge funds whose transactions are executed domestically but operate in a foreign jurisdiction. In Canada for example, an offshore fund may have a de facto management team based in the Bahamas but retain an advisory team in Canada. The advisory team executes trades on behalf of the management. There is some ambiguity as to whether a transaction through a Canadian internet service provider may constitute a "carrying of business in Canada" which would subject the fund to local securities and taxation implication. Again this a grey area and no clear lines have been drawn by Revenue Canada. My line questioning is proactive, If Interative Brokers cannot determine ( which I believe they can) then this issue becomes moot. If they can determine your ISP will countermeasure such as Secure Proxy Servers outside of Canada be effective in eliminating IB's trace to a Canadian Server. Thank you, Any help would be greatly appreciated.
