In thin trading Tuesday night, by breaching the 913.90 Hidden Pivot midpoint of the pattern shown in the chart, the April contract has tripped a signal implying a fall to 886.70 is imminent. A bounce from near 907.20 is likely in any case, and if that bounce were to surpass at least two prior peaks on the 15-minute chart, we’d give bulls the temporary benefit of the doubt. However, the rally would need to touch 927.60 today to decisively reverse the now three-day slide.
