Update

The indices like SPXEW,DJ,NYSE,DAX declined to MA200 then retraced to MA50 and all this took 2 months or one 10w cycle. Next week the decline should continue. NDX made higher high, was this the top of the pattern or just b-wave - difficult to say. At the end it does not matter this is important top expext decline for 9-12 months to test MA200 weekly.
P.S. as usual the "experts" showed up to nail the top.

I think we should see a few days higher for b/2

According to the short term cycles we should see a bounce for a few days.

If the SPX has the same cycle model like the other indices we have 10w cycle high after 18m high and this is the NDX again with perfect three cycles but 10w cycle difference.
