Blog post: 30th day of $QQQ short term up-trend, GMI falls to 4 (of 6), more new lows than highs but weekly chart of QQQ shows strength; I always check weekly chart before selling

I always check the weekly chart before selling anything. This chart shows that the up-trend in QQQ is intact. A weekly close below the 4 wk average (red dotted line) would be first sign of weakening of an up-trend.
