I called for a technical failure if the market broke below 625.00, which it did yesterday. Support right now is around the 611.80 area (50% retracement level of Oct low to Dec high). Also in tandem with the lower daily Bollinger Band. If that is violated, next stop is 602.00. VERY large open interest in the 600 options, so there is a real possibility to test that level if 611.00 is violated.
