Silver kept the bull trend robustly alive with a spike yesterday that slightly exceeded a look-to-the-left peak at 18.585 recorded on June 1. The overshoot was just 3.5 cents, but that’s plenty enough to suggest that more upside awaits following tonight’s so-far gentle consolidation.  A more daunting peak at 18.815 will be today’s challenge, but the futures looked to be in good shape to take it on as of around 8:25 p.m. EDT. A surge from here above $19 would provide a psychological boost as well, since it would badly compromise an all-too-clear head-and-shoulders pattern visible on the intraday charts.
