I am assuming you posted the details of your situation over at FPA. Based on specific information, I would think what the broker did is highly contentious. Whether you have any practical recourse against your broker is another matter given the jurisdictional authority. The fact is your position was stopped out based on a spread of at least 220 pips. relative to where trades were taking place during that session and immediate sessions would suggest something that is highly irregular. Your case is an example of why choice of broker and jurisdictional oversight is important.
