There is NO TOPPING PATTERN YET for the S&P. Until something changes, this is still a Bull rally (even if it is over-extended). Price could drop quickly, but sideways & down is the more probable scenario.
The Measured Moves are derived from the Reference Range; each tier is a clone of that range. I tested it going back down, and one can see it fits pretty well.
There is a similar scenario with the small caps (Russell 2000/IWM), which is described in related postings given below.
