When the S&P started rolling over in October 2007 I considered, but then laughed at the possibility of a double top of such huge proportions. Now with the February monthly bar closing today it has confirmed itself. And what's worse is it closed on it's lows (daily, weekly & monthly). Next support should come from the 605-681 range. If it trades through that, and it certainly could, it won't find support until 482, the 1994 tops. Of course this is long term analysis for position trading. Daytrading and swing trading will be business as usual.
