Two weeks of upward progress, if you could call it that, have failed to produce even a single new, bullish impulse leg on the hourly chart.  The futures therefore remain vulnerable to a fall to the trendline we’ve been monitoring, which comes in today at 17.375. Alternatively, it would take a thrust, merely, to 18.845 to send bears diving for cover. ______ UPDATE (1:16 p.m. EDT): Today’s nasty spill actually projects lower than the trendline — to 16.830. The midpoint support at 17.680 will offer bulls a last-ditch opportunity to turn things around, but if it’s breached on a closing basis, brace for more downside to 16.830.
