SPX cleared and retested Intermediate-term support/resistance now at 2256.83 this morning. It was a pleasant surprise to see it begin a new impulse lower. Although shallow, the new impulse tells us that there is room to decline. It is also a prime candidate for a flash crash as early as today. If the decline remains impulsive and gains momentum, we may see a low as early as Tuesday mid-day. SPX is on a sell signal.
