March Silver should be presumed bound for at least 18.120, a Hidden Pivot support, but any lower would put its ‘D’ sibling in play: 17.890.  Both numbers can be bottom-fished with a stop-loss as tight as three ticks, but because the futures fell so steeply yesterday, I wouldn’t advise getting in front of the move too aggressively. Alternatively, it would take a pop today exceeding 18.495 to turn the 5-minute chart bullish.
