I have been trading FX using questrade for a few months now. Have about 200K in there. I had 16 lots longing USD through many pairs. One day I get a call from questrade saying that I have to close $50,000 worth of USD position or else they will close it for me I was told this is nothing to do with my margin as my positions are not good for the company. I went down to their office and I was told the same thing. Later that day, they close some of my USD long positions. My margin was still good. Is this normal?? Can they close a position for me even thought my margin was good and just because it's not good for Questtrade?
