    Wavelet Discontinuity Watch (4-hour frequency close ) :

    Overall commentary for Jan/21/2011:

    NeuralNetwork Trend is DOWN, but still with weak confidence.

    Filtering Trend is up with decreasing momentum. This usually lags the neural trend model in turning points.

    Markov Regime Switching identifier probability of DOWNTREND / VOLATILE REGIME is still very high at 43.7.  It´s usually a reliable signal. Since last week when it climbed above 20% this model is warning of an imminent regime change, that finally happened this week. How long will it last ? Let´s keep watching.
    SPY-VIX relationship reached the 22% percentile. It has more room to go down. Short term tradable bottoms usually see this indicator around the 10th percentile before a sizeable bounce occurs. So, odds are the bottom has not yet occurred for this down move.

    Wavelets models both intraday and daily are flashing high volatility and increasing risk of a big move. So better trade with caution.

    Good Trading.
