The pattern show in the chart speaks with authority because of the precise delicacy of its ABC coordinates, and because of its labyrinthian obscurity. It projects downside to 717.30 (see correction note below), which would amount to a 6% slide from these levels. The Hidden Pivot midpoint is 755.20, and you could bottom-fish there with a very tight stop-loss, since it is as likely to produce a tradable bounce as the ‘D’ target itself. _______ UPDATE: So far this morning there has been one bounce on the way down, from 757.20, but the midpoint pivot noted above evinced no support at all and would have been a small loser for anyone attempting to bottom-fish there as suggested. The futures subsequently rebounded to play toe-sies with the midpoint, but the damage was already done, hinting of more weakness to at least 717.30. This target has been corrected to reflect my misreading of point B, which is 761.80, not 765.00.
