a minor sign of weakness on the SP500 Pulse Chart

In early September Momentum (PriceOsc) turned positive (arrow). Since that point there has been seventeen days when Aggressive Buying (green) has been marked. There wasn’t a subsequent close below the lows of those Green Bars until yesterday. That pattern, indicating a strong up-trend, was broken when Tuesday’s close was marked below Friday’s green-bar low. Note that no Aggressive Dayframe Selling (red) has yet been marked but yesterday’s price action may indicate a slowing up of the daily trend – note also that the PriceOsc has turned down.
