Choppy but still working on a (v)th.
While SPX can certainly force this back to an impulse if it wants, ES fading back from the attempted breakout last night makes it look more like an ED for micro C of a of (v) of the LD (purple sub-waves).
Normal supports for B are, 2733.50, 2729 & 2724.75.
C of (3) could target 2763 rather than 2771 and (4) is likely to fade more too.
