If you don't sweat the small stuff, there is a potential diagonal in the ES 2-hr futures which roughly squares with a cash count on the SP500 of a fifth wave up in this series. First, here is the chart.
'Potential' Diagonal is the ES 120-Minute Futures
Next, such a diagonal is adhering to it's trend lines well. Third, any new higher high in the futures, whether or not a similar one is made in cash, could end this wave. Fourth, however, the diagonal 'must' form properly in that wave (v) must be shorter than wave (iii). Fifth, and last, there would need to be a complete retrace, below 2144, to call this diagonal an "ending" diagonal, otherwise, it 'could' be leading.
But lots of divergences are building -- so at least exercise care until we know if (v) is shorter than (iii) or not.
