The current US paper price attempted to break through this level a number of times around 08 to late 09. It was solud resistance and once broken many shorts did thier pants and let it run up quikly to 1800 or so.
So we find this level is now a support built like an old bluestone footing. It is not going lower.
Oh for Skol, some of your bookselling analysts would be following thier stops and getting out of stocks today, looking grim. One I read in particular on thr,advancing or retreating box on breakouts (Guppy) would be running today.
