I made a stupid mistake today: I shorted bonds at 121'285. It is refusing to move down so I can get out. I did the trade just for a quick profit, but the damn thing moved straight up immediately after I made my trade. By the time I prepared the stop loss/take profit orders, it was at 122'05. When will this thing go down if any? Should I take my loss, and move on? If the US credit situation were that bad, how come they are buying the bonds?
