My sell order on UPS has not triggered, I’ve tried to cancel to put on another in order to exit the trade but the old order, despite saying cancelling, is not cancelling, so I am unable to place even a market order. I’ve had a message to say the order being cancelled can not be cancelled but it’s not triggering either. I’m stuck in this trade forever. I am now back in profit since and just want the order to cancel so I can set another before I go into a loss again! Help!
