Near term, both legs of the down-up sequence from 1.5904 are not clear impulses. This makes it likely that a larger correction is underway; either a triangle or a flat. It is possible that waves A through D of a triangle are complete and that wave E is underway towards 1.5600 or just below.
E waves of triangles are usually sharp and have a tendency to penetrate the lower triangle line. The triangle line crosses through 1.5593 tomorrow. It does remain possible that a larger correction is underway.
