two sessions closing lower, from 355.16 to 343.80
today's jump of 3.50% has undone that fall and put price back above the 353.98 level
Clearing the Sep 29 high of 361.85 would extend the rebound into the 365-375 area; a close below today's low of 347.47 undoes it and puts price back inside the 343-355 area it just left.
