Some chartists calculate ABCD patterns in the way shown, but I have found the targets of such patterns to be less reliable, and therefore less useful, than the ones we typically use.  Even so, as a way of predicting how far this bear rally might go, the ‘D’ in the chart, 8107.59, is worth considering.  That mutant Hidden Pivot, incidentally, is 20 points above the 0.618 line of the decline from early January’s high.
