LT, at this point I am just speculating, but YR1 is going to be around 5200.
OTT, after this current dip is contained above 4398, then we get the move to circa 4950. It could form a double bottom, afterward, then we get the move to 5273. That whole scenario is also speculation. What I am not speculating on is 4398 or higher to contain this leg of the DOWN. The market will have the WS2 at 4471 and the MS2 at 4445 to contend with, At this point they could also contain.
Confirmation that the correction has start will be 4768. You 'll know it, because there will be a very strong move through it. That level is dynamic, and it drops everyday.
