Confirmation of the more immediately bearish dark red wave count on the 30-min chart would be a break below Tuesday's 810.48 high. That would point towards the larger leg down to the 750-760 area before potentially setting up a stronger rally. The pink wave count is looking for a 5th wave for the rally off Monday's low and that's why I'm watching the parallel up-channel. It says we could see another rally leg up to about 857 where the 1st and 5th waves would be equal.
