It’s official: The E-Mini S&Ps are about to leap at least 70 points, to 1769.50, catalyzed by the seemingly inevitable choice of Janet Yellin as Ben Bernanke’s replacement. Those of you who are familiar with Hidden Pivot dynamics will be struck by the way tonight’s short-squeeze has gapped effortlessly through a midpoint resistance — one that was all the more daunting because of its close proximity to the old record high. By our runes, this all but guarantees a run-up to the 1769.50 ‘D’ target (see inset) with which the midpoint pivot is associated. That would be equivalent to a Dow rally of about 600 points, so traders should take an aggressively bullish stance between here and the target.  Please note as well that a retracement on Monday to the 1693.90 midpoint or very close to it would strongly imply that the rally will top, at least short-term, at exactly 1769.50, making it short-able. ______ UPDATE (September 17, 12:22 a.m. EDT): Early Tuesday morning, the futures were poised to stairstep lower on ‘D’ pivots that lay, successively, at 1684.75,  1683.00 and 1681.75 (5-min, A=1698.50, with various B-C combinations).  Very precise action at the 1688.00 p midpoint associated with the 1683.00 target suggests it will be the best place to try bottom-fishing with a straight bid — i.e, without ‘camouflage’). Accordingly, I’ll suggest attempting entry with a 1683.25 bid, stop 1682.75 (!) This set-up looks very promising, but because the rally could be fragile, be prepared to take a partial profit on an initial move of as little as 4-5 ticks.
