A Hidden Pivot at 892.75still looks compelling as a minimum upside target.  The midpoint sibling of this number  is 857.75, so any pullback to that number should be viewed as a possible buying opportunity. One way to take advantage of this conservatively would be to place a tightly stopped bid  at a minor-retracement ‘d’ target or c-d midpoint, but the tactic is best attempted by someone familiar with Hidden Pivot Method.  As you can see, the swoon in the closing minutes of Friday’ session brought the futures down to within a point of the 857.75midpoint pivot.  _______ UPDATE (11:02 p.m.):The futures are getting demolished Sunday night and look bound for846.00 or worse. That’s a Hidden Pivot support, and if it’s easily breached, the next target in the sequence would be 839.50.
